alright. i know lots of people know this already and lots of people dont so i'm writing of how i did my cams. please give remarks as to do something better or if i did something incorrect. this was my first time working on a jz motor.

must have items (imo, unless recently replaced)
1. cams (duh)- i personally bough the 272 small cores
2. cam seals x2- 90311-38041
3. cam cover seals x 2- same as 2jzgte

recommended tools and materials
1. flat head/ mini mini flat head.
2. phillips long and a shorty
3. 3/8ths ratchet with 10/12/13/14/17/19mm socket. 6" extension/ 15ft lbs torque wrench or something that can read that
4. 1/2" breaker bar/ratchet/ 22mm socket/ 3" extension/ 250ft lbs torque wrench/
5. toyota fipg is a must!
6. same oil you have in your engine..buy 1 quart.
7. coolant 1 gallon
8. 1/2" or 3/8th cordless impact is VERY helpful. i used a 14volt one and they are so cheap now and days its always good to have one anyway.
9. FEELER GAUGES
10. micrometer that reads in detail .001 increments.
11. plastic or soft face hammer
12. lots of cloth/rags unless you want to be messy
13. 5mm allen socket and 10mm allen socket
14. crank pulley puller...cheap. like $18.00 from schucks/auto zone
15. black sharpie OR white out

note: i do not have a 1jz tensioner/i just pivot my p/s pump up and down for tension and i do not have a upper timing cover, but i'm sure you are smart enough to take off the belt and the upper cover by yourself.

start out with a vehicle equipped 1j. my example

make sure the vehicle is cool and drain the coolant. using a 5mm allen socket...remove the coil cover bolts.

remove your radiator and upper radiator hose. remove upper timing belt cover exposing the belt. take your 22mm socket and put it on the crank pulley bolt. turn CLOCK WISE until your timing marks are lined up..like this. you can see that in the backing plate of the cam gears there is a verticle line dead center. align with that line.


on each cam gear there is a little notch as you can see in the picture. right on top of the notch...use white out or a black sharpie and mark the belt. be very VERY accurate. this is vital. i took this picture a little late..after i already turned the crank again..but you can see the marking on the belt.

take off your serpentine belt
take off your water pump/hydro pump pulley. this is where the cordless $40.00 impact gun came in MUCH handy. i tried w/o it and i was lifting the whole front end sleightly up...it needs something to hit it constantly..fast and hard. i guess you can call it the pamela anderson nut. this is how it looked. i jammed a screw driver in one of the wholes of the pulley to prevent it from spinning and took a 17mm with the impact and knocked it loose.

after that you can now proceed to undo the crank pulley bolt. get a breaker bar. you MUST use a breaker bar. if you use a ratchet you can possibly break the head components of the ratchet. it should be a 22mm socket..put the breaker bar resting against the DRIVERS SIDE frame or ground like this.

now pull your efi fuse out in the fuse box engine compartment..and give it a very quick .5 second click. that SHOULD be enough to break the bolt loose. it did on my engine. if not try it again...if it still doesnt i feel sorry for you. you might have to find someone with a very strong impact. you should not proceed the starter method because you can damage the starter teeth if its that tight.
now that you have your pita crank bolt off...grab your crank pulley puller. it looks similar to a steering wheel puller. some has have success using long bars/ flat heads going from underneath but i do not advise this. you can damage the the pulley or other vital things. there is 2 bolt holes on the crank pulley that you can put bolts in. this is why i love toyota and this is where you are going to insert the bolts from the pulley. my pulley came with the bolts needed. looks like this. you can rent tools like this too for dirt cheap.

a ratcheting wrench is very helpful for this part.
after you successfully loosen the crank pulley and the dampner together...undo the 10mm bolts for the lower timing belt cover. to loosen the tension from the timing belt there is a hydraulic looking thing holding tension against the device which holds the timing belt pulley. looks like this.

the allen is a 10mm for the idler...crack that loose, and you can see where the bolt is for the tensioner. there is two...one on each side of it. you will need like a 6" extension to get to the left side bolt. take those two out 12mm bolts. and you will lose the tension on the timing belt. take off the belt and set it somewhere dry and away from fluid. now take off the cam gear bolt. i believe its 17mm. after taking the gears off take off the back black plate behind the cam gears with a few 10mm bolts.
now undo the wiring for the coils.

move those wire aside and take out the coils. after that undo the stupid phillip screws for the cam covers. it would not be a bad idea to switch over to regular 10mm bolts to replace those stupid phillip head at this time also. the phillip head tends to strip..esp the far back ones.
because of the center cam cover connector..move both of the covers as one and set it aside.
this is the order in how to install the caps...so i also use this order to remove them. from the furthest cap to the main cap housing the cam seal is:
2
5
3
4
1
6
7
write that on a paper next to the engine and just look at the paper. w/in 2 times of doing it you should remember the sequence...trust me.
okay so now you have the caps off and KEEP THEM IN ORDER..caps should go exactly where they came from. put them aside on a cloth and move those puiny little cams out. i will miss the mpg though :(
now the fun mathmatical part. on a paper mark it something like this:
I1- E1-
I2- E2-
All the way down to I12 and E12. if you want the last shim to be 1 thats fine..thats what i did..if you want the first one to be..thats fine to..as long as you remember. this is how to take the shim out. on each bucket there is 2 notches..use your super mini flat head and or magnet..something like this:

just pop it out of there. wipe it off nice and clean....take them all off and keep them IN ORDER. after they are all off..measure the thickness with the micrometer and record them. example for me...i take off the shim from the last bucket on the exhaust side..measure it. it came out to be .113" so on my chart i will write.......E1-.113. as soon as you measure it..put it back in the bucket it belongs to so you dont mix them up.
after they are all measured and put back...open your black crower boxs and do not get blinded from the light escaping.
this step is option but i recommend it. there are 2 half moons..as i call it..in the back valve covers. they can be knocked out with a flat head. just pry on them....cleaned..and put fipg on the bottom surface. just a thing layer across the whole bottom. clean all your surfaces very well. this is the half moon thing.

put your cams in. they ARE MARKED. it'll say 2jz e...2jz i..e for exhaust side. exhaust side is on your left hand. i for intake...right side..duh. anywho..put them in..it might seem like it doesnt want to go in right but it will once you tighten it down. do not install the new cam seals at this time. put the caps on in the sequence i told you earlier.front to back 7614352. put them on using three stages. first stage a little tight...second stage tighter..and then torque then in that same order. i went 15ft lbs. you might need a different torque wrench as much 250ft lbs torque wrench does not go as low as 15.
now for where most people get confused. throw your cam gears on and put the cam bolts in. remember this is temporary only. which ever side you do first, turn the cam until the first set of lobes are facing up. pointy side up like so:

now the specs that are used are

intake .006-.010 and exhaust is .010-.014"

remember...that spec is in inches. so for example you turned the cam, lobe you're doing is facing up, its on the intake side. so it should not fit any gauges HIGHER then .010 BUT should fit at least a .006. and same deal for the exhaust side. it SHOULD NOT fit any guages higher then .014 but SHOULD fit at least a .010. just stick your gauge in there but be careful because if you force you might bend the gauges. now what i did on the sheet of paper is next to where i did the readings for each shim..i will scribble it out completely if its good..IF NOT...this is an example of what i'd do:
shim/cam lobe 1 intake side measured earlier w/ micrometer at .114. you just put the feeler gauge in and you could fit a .014 in between the lobe and shim. you should not be over .010 according to specs. so that means that there is too much slack. which means you need to find a shim at least .004 bigger. .114-.004 equals .110. write that next to the spec/cam number to indicate that this is what you need in that bucket. measure all of them...when you are done..find out which ones need to come out...find out if you can swap some out. when you order them make sure to bring the micrometer with you to measure them infront of the persons face unless you order phone/online.

be smart about switching them out. i honestly cheated because stupid toyota parts person (shoulda dealt with champion) ordered wrong shim. it was for the intake side and i could only clear a .005(too tight). it was .006 to be within spec. but i said "what the hell"..i coudlnt wait a few more days and went for it. i'm not saying its write, but i am saying i got away with it. was using fiance's parents garage so had to get it out of there.

now. after you swap them around and what not...call toyota (champion for best price) i think its $6.60 each. thats the price jeff quoted me. tell them what you need. take the caps off...replace the shim...now that all the caps are on you can proceed to finally finish this all up because everything is w/in spec. with all the caps properly torque..take off the cam gear bolt/cam gears/ and the cap which houses the cam seal (very first caps). clean the caps real nice like so :

and put fipg on the little cannels on the bottom surface..thin layer like so:

that stuff dries up pretty quick so be fast about it. put those caps on with fipg/ and but the bolts loosely on. why loose? because you have to put the cam seals in. take the cam seals..put some oil around the cam seals. some say this isnt nec because it comes prelubed..but i still like to. now put them on CAREFULLY!..the reason why i wanted youto put the caps on loose is because the spring in and behind the seal will pop out of place if you do it wrong. sleighly put the seal on and look behind it...spin the seal around gently so you can make sure the spring is w/in place ALL around. slide the seal all the way in...tighten and torque your caps.
now put the new cam cover seals on. you might notice it looks like this:

its okay because it will straighten out as you rest it in place. put the covers on as one and be careful that the seals do not fall out of place. it can and you probably wont even notice..so after they are resting on the head i take a flash light and small flat head and poke the seals to make sure they are still there and in place.
like i said, not a bad idea to replace these phillip bolt with regular bolts. it will be a lot easier to tighten down.
after they are tighten put in your pcv thing on the intake side or however you have it hooked up.
install the black back plate that goes behind your cam gears. install the cam gears and bolt. i didnt torque these..i just went at it sleightly with my cordless impact.
with that in place put in your coils and put the wires back in them. its pretty much impossible to screw up which plugs goes where. put the coil cover on with the allen 5mm and its allen bolt.
now proceed to the timing belt. place the cam gear marks directly UP to line with the back marks. put the BOTTOM cover in place and just hold it there with the center bolt. this is temporary. with the cover in place, put your crank pulley back on and then the bolt. do not tighten the bolt down..just put it in place till the crank starts turning. turn the crank till the notch on it lines up with the 0 mark on the cover like:
http://i118.photobucket.com/albums/o96/yuepeng05/cams install/Picture037.jpg
take the bolt and the crank back off so you can put the belt on. now find the timing marks you marked earlier and match them to the notch on the cams. hold the belt down with your left hand and with your right hand tighten it down from the right and around the crank shaft. there should be NO SLACK ON THE RIGHT SIDE. put it over the pulley and let it rest there...tighten the bolts on the tensioner and it should slowly create tension. now that the tension is on it tighten the 10mm allen...put the lower timing cover on. if you removed the weird washer thing remember to put that on before putting the cover on. now the crank and bolt. tighten it enough to turn it around 2 times. reason is to make sure the the belt doesnt loosen up.
check the tension to make sure it didnt loosen up. now throw the trans in 5th gear. i put the torque at 235ft lbs because even at 240ft lbs the whole vehicle started moving. make sure you use are either sleightly strong, have a friend, use a long ass bar on top of the torque wrench, or know the hulk, magneto (x-men), or rose (x-men...women)
put the water pump pulley back on/ upper timing cover back (i'm cool so i dont have upper cover)/ and the belt tensioner and the belt. now radiator goes back and coolant. make sure everything is in place and start her up.

on my part, it was VERY hard to start up and DID NOT want to idle at all. i had to drive around for awhile for it to want to idle and then i had to adjust the fuel. it might be because i had a cold start up issue at first anyways.

i had to remove a bit of fuel on low throttle

VIDEO COMING SOON! the aftermath is AWESOME. It is so different. sounds like a v8 and the power is undescribable. i swear i was laughing and smiling the whole test drive. i think i shed a tear.

please chime in for experienced people and tell what you would do different or could do different or shouldnt do or do. thanks! enjoy the cams.

NOTES: i did not and do not advise using the toyota sst tool or buying it from matco. it was a waste of my money and if its your first time using it, you will prob spend 10minutes on 1 shim with that stupid tool. i think its easier and faster taking the caps off. i just dont have the skills like some.

Re: the official "how to install cams" guide (pics)

Are you going to degree them or are you leaving them like they are?

I see you have stock cam gears so I don't think you can degree them. I'm wanting to have mine degreed when I install them again.

Re: the official "how to install cams" guide (pics)

i'm not going to because i didnt want and i thought about writing about that, but wanted to keep this as straight forward as possible. i figure if someone is curious enough they can look that up, but thanks for mentioning that.

it runs excellent non degreed so i'll stick with it for now. the power is almost unbareable. 80+mph breakin loose

Re: the official "how to install cams" guide (pics)

Once you install the new cams, their is an easy way to shim the cams without taking them out. I will post pics of the tool that I use to compress the spring and another tool to hold the edge of the bucket to keep it down while you pop the shim out with a screw driver, magnet or compressed air. It takes patients and the two rear buckets by the firewall are tricky but I got them in when I installed my 272 small cores. You can get the tool from any major tool company mac, matco, snap-on and its like 25$. Also make sure after you shim your cams, that you rotate the engine a couple of times to seat the shims because the tolerances will slightly change once they seat.

Re: the official "how to install cams" guide (pics)

man you are good then, lol i bought the tool from matco...the little plier pincher looking thing with the flat metal piece. i sucked at it so bad. please show your trick. i could get the shim to hold down but where ever i held it down..the shim would pop up but have no where to go cuz of the tool holding it down.


i'm selling the tool for anyone who wants to try it. its brand new. i also have a few shims left over:
.100 x2
.113 x2
.114 for 1

Re: the official "how to install cams" guide (pics)

y:biglaugh::biglaugh: yah sometimes you have use brute force to knock the shim in and out, but it doesn't mess up the shim. I work for nissan and I have done a bunch of ka24de's which are the same style and also my 1jz, so I have a lot of practice. Yah, a bunch of times the holder will pop out when the shim is only half way out making it a complete bitch to get it out , but then I just take a flat blade screw driver and just put it against the shim and hit it with a hammer to pop it out. Not by the book, but it works, and it doesn't mess up the shim. Sometimes a perfect screwdriver works better than the holder to hold the bucket down.

Re: the official "how to install cams" guide (pics)

good write up.

Make sure to wipe away all oil between the bucket seat and the shim.

Threw my measurements off once measuring with the shim.

EDIT* I just verified my clearances after 1 year of daily driving, putting at least 30-50 miles on the car per day.

ALL of the intake and exhaust shims are where I left them on the tighest specs called for by Crower with their cams. I am on dual ferrea springs, OS valves, and 10.3mm lift Crower large cores. Thought I would share after 1 year of use with the large cores.

Re: the official "how to install cams" guide (pics)

wanna hook a brother up with that damn tool, I knew it exsist but I didn't have it so.. yes I took the cams out every time.

I did buy the keeper removal tool though. btw if you change springs and retainers, best way to get the keepers out (my little secret) use a 13Mm socket with a ext, and tap it fairly hard with a hammer they will shoot out and stay inside the socket for easy collection. putting them back i recommend the speical tool.

Re: the official "how to install cams" guide (pics)

i just push on the bucket with a flat head screwdriver and suck the shim out with a magnet.this is the tool i used to pull the retainer and keeper's.it's magnetic and all you do is puch down on the spring.

it come's with another piece for installing them too

i also used a spark plug boot tool to pull the valve seals out

Re: the official "how to install cams" guide (pics)

tsuper92 has the BEST tool for removal and installation.

when you buy the tool (any matco/snapon should have it...even auto parts store should...as i think i bought mines at sears) it'll come with instructions.

as you guys can see in his pics, one end you put on top of the retainer, give it a good wack, the retainers pop out and the magnet catches the retainer.

when you install it just put the retainer back on top neatly...use the other part of the tool and give it a nice hard push and it should nicely seat on the valve.

to install the valve seals, i found out from a master tech that using a 12point 1/4" 10mm deep socket fits PERFECTLY over pretty much all toyota valve seals. remember to give it a sleight lube when installing.

simple as that.

Re: the official "how to install cams" guide (pics)

i have that same tool tsupra, however mine was bulepoint or something sanpon's cheap line or some garbage? cost me 70 bucks, but man does it save time...

I still find it easier to do the hammer and socket to pull the keepers out.. one bang and both fly out and you juse use a mag to pick em up from inside the socket.

if your head was just reshimed, would you have to reshim it again if you install cams?

Re: the official "how to install cams" guide (pics)

yes you do! every cam is sleightly different. there is none that is EXACTLY the same.

by the way i'm jealous of your cressida with that sickass turbo. i'd love to have one of those but too pricey.

this thread would be great also if everyone gave shim numbers they arent using so it might benefit other people.

Re: the official "how to install cams" guide (pics)

thanks :) yeh part #'s would be awsome! or what shims fit the 1jz lifter bucket? like other engine ect or will a 2jz shims work (if they take shims.......) with 272's would you have to beef up your springs/retainers? im not surei want to go that big more like 264's?

Re: the official "how to install cams" guide (pics)

dude, go big! you wont regret it. i have 272 small cores and stock springs/retainers...doing just fine. pulls HARD all the way till redline. i only lost 3-5 mpg.

2jzs will work.

honestly when i worked for toyota everyone had a bucket of shims and we would always just mix and matched..from camrys, supras, 4runner, etc... but a few people here have said that only 2jz and mr2 shims work so i'll stick with that statement if i were you.

Re: the official "how to install cams" guide (pics)

What is the estimated time to install the cams? Just curious since I'll be doing it soon with 2J cams.

Re: the official "how to install cams" guide (pics)

panchira- 2jz shims are the same. so are mr2 turbo shims.

honestabe- time can not really be said because you wont really know what shims you'll need yet, if you need them, if the dealer stocks them, if you buy from out of state sources, etc...

if this is your first time tearing apart a 1jz and you get lucky and need no new shim..i'd say give yourself a good 6-8 hours. at least for me because i get really picky of doing things and i'm really self caustious. i check, recheck, and tripple check everything.

to call it safe i'd say give the down time at least 2 days. one day tear everything apart early in the morning, order new shims... wait for local dealer to order them and it arrives next day. you're in oregon so it shouldnt really be a problem for you. lots of toyota dealers to share parts.

hi all sorry for pulling this old thread out, i just have a few questions.
i have purchased 2jz valve springs for my car will my 1jz retainer + buckets fit these spring or do i need to order new retainers and buckets??
whilst im doing the springs im also going to do the stem seals, any advice for ease of removal/installation and also will 2jz stem seals fit the 1jz??
and are the clearances provided (0.006-0.010 + 0.010-0.014) are these factory specs??

Make sure they sit flush before tightening them down. Front of the cam where the seal goes over needs to be over the journal on the front of the head. Make sure it is or you can snap a cam.....

Re: the official "how to install cams" guide (pics)

Changing a camshaft is simple if you have some help in the confusing corners. We did our cam swap in about an hour on a chassis dyno, using air tools; an in-car installation with hand tools takes a bit more time. The first step requires removing and labeling anything in front of the timing-chain cover and on top of the intake manifold. Once the coolant is drained and the accessories are out of the way, remove the intake-manifold bolts. A small hammer and chisel or flat-head screwdriver may be needed to pry the intake manifold from the engine block. The cork or silicone gasket material in this area will be replaced so damage is not a concern. After removing the intake manifold, scrape the front and rear block rails clean of cork, silicone, oil, or any other foreign substance. Line the lifter valley with paper towels to capture the debris.

Remove the valve covers to access the rockers, pushrods, and lifters. Keep the rockers and pushrods in order. While you remove the rocker nuts, the engine may have to be turned over a few times in order to take valvespring pressure away from certain rocker-to-valve stem contact points.
I searched it from google....

Remove the valve covers to access the rockers, pushrods, and lifters. Keep the rockers and pushrods in order. While you remove the rocker nuts, the engine may have to be turned over a few times in order to take valvespring pressure away from certain rocker-to-valve stem contact points.
I searched it from google....
No offense, but get that shit out of here. First we don't have chain, rockers, push rods, or lifters. Secondly the manifold does not have to be removed. third, you should just delete your post.

Newb question im sure but im going to be installing bc 264's and Ive never dealt with cams. Do I have to rotate the motor as I rotate the cam to measure shim clearance to avoid interferance or can i just rotate cam by hand/rachet to get measurements? do 264s even make it a interference setup? Do you guys go through the whole process of installing the tbelt to rotate cams? The guide kinda goes off track after the first measurement

Hi,

No sir. You do not have to rotate the whole engine or put the t-belt back on. Just make sure you tighten the cam caps properly and put the cam bolt back in. Put a socket to that bolt and turn the cam. These are non interference engines so you're safe. sorry for the confusion. even the 272 are non interference if you have the small cores. Key word, small core.

Thanks for the fast reply, i've followed the guide and tsrm exactly and i'm at the point where i'm checking shims... I check the first 2, but when i try and turn the cam it turns and I can see the shims compressing with ease, then it just stops and will not turn period.. any thoughts?

EDIT: Never mind i'm retarded, we were using the new bc cam gears and it was hitting on the damn timing cover bolt.. problem sovled!
