View Full Version : GrimJack's rebuild
GrimJack

Or vent, if you prefer. ;)
Last night I finished assembling the bottom end - with the exception of the rear main oil seal & assembly and the oilpan, I'll do those pretty much dead last - but before I remount the tranny, of course. I had already re-assembled the head previously, so now it's just a matter of bolting parts back onto the engine and dropping it back into the car.
Injectors are currently in getting cleaned and tested. Engine will be silver and black with occasional highlights in red when I am done.
After having the block, crank, and rods checked at my machine shop, I had the crank polished, the cylinders rehoned, and added in new hastings rings and clevite bearings. Add in a nice finish on the head and block deck and a good cleaning all around, some new valve seals, and an HKS MHG, and I should be good to go.
For anyone not familiar with the history, I blew a stock headgasket, destroyed the rings and turned the ringland on piston #2 into sharp bits of sand in the oilpan, plus I had a mild rod knock on #5. There is an entry in the carnage thread with pics. This proves that 20psi on an upgraded turbo is enough to eat a stock headgasket eventually - it did run for over a month before blowing up, which IMO is testament to the fact that the 7M is actually a damn tough engine.
PS: Many thanks to the folks that have helped with info over the last 6 weeks, especially Adjuster. :D And more thanks to those that have helped with labor, especially VanSupra. I owe you both a nice dinner soon!

You going to Vegas this Year?
I'll be there, and they have some great restaurants.... LOL.
Seriously happy to see your engine is coming together well. Hope that the assembly and minor mods you've done add up to a very nice reliable motor that will handle the 20psi + that your shooting for.
GrimJack
09-28-2005, 05:28 PM
I'd have to be very lucky to get it all together, running, and broken in with enough time to spare to make it to Vegas. But I just might... :) I honestly think I'll be happy with 20psi or less, I not as greedy as some of us. :D
Picked up the injectors today, they came out nicely. I had no idea that injectors have a built in filter! I think I need one more hose from Toyota, and a bunch of cleaning, painting, and install time.
Don't forget some pics Grim ;)!

I'm assuming you used stock pistons for the rebuild then?
GrimJack
09-29-2005, 01:42 AM
Not just stock - but my original pistons for this block, as a matter of fact, just cleaned up.
Here are some pics as she sits at the moment.

And a few more pics... including what the REST of the garage looks like 6 weeks into this rebuild!

Nice garage Dave..Your wife must love you alot..Are you still getting any?
:icon_surp
Glad you two made it back from your cruise in one piece. lmk when it's hoist time.
SupraMario
09-29-2005, 11:49 AM
did you have the block dipped?
or did you scrub it down/
GrimJack

Actually, the machine shop cleaned it manually. The fellow there didn't want to hot tank it, as that would trash the oil pump driveshaft bearings, and they were still in perfect condition. It would have killed the frost plugs as well, but that didn't turn out to be an issue because I had them all replaced anyhow.

If he would of hot tanked it in the aluminum cleaner the frost plugs and bearings would have been fine. Just had mine done like that and the plugs came out fine...it is a bit more expensive though.
I can't wait till my garage looks like that, soon :D
Looks like the motor is coming along nicely Dave, keep up the good work :bigthumb:

Grim, you've come this far and a new oil pump is only around $150. Get a new one.
GrimJack
09-30-2005, 12:50 AM
No new oil pump! I considered it very seriously, however, my machinist checked the one that I have and tells me that it has literally zero wear on it. Not really surprising considering that I still have well under 100k on this engine.
Oddly enough, I had to drill out one of the rivets on my HKS MHG, or it would have been crushed when I torqued the head down - on the very back on the exhaust side. I'd suggest that everyone check all the rivets on their gasket, whatever the brand happens to be, before bolting down the head, ESPECIALLY if you've had the block machined more than once.
More pics... the blue headgasket is what it looks like after you spray it with permatex brake quiet!

Tell your machinist he/she can pay for the next rebuild.

Believe me, if my next rebuild is any time soon and related to oil starvation, we'll be having a conversation that he will not enjoy. :D

Beautiful! Good luck with the rebuild GrimJack! :)

What have you all done so far to it? I'm getting ready to start my rebuild and trying to figure everything out.
SupraMario
09-30-2005, 08:25 PM
Video? What kind of video are you looking for?
engine video so i can do like a before after thing of your car, for the video im going to make, if you dont want your car to be in it then you dont have to post up a video, but that would make me cry.:cry: <--- see like that guy.
GrimJack
10-01-2005, 02:45 AM
Just a video of the engine running? Or something as it is going into the engine bay? Or as it's being built up? I've got no problems donating footage (tho getting longer than 30 second clips into the computer is tough for me at the moment, I don't have a video input device) I just need to know what kind of footage.
Loki, I've done a fair bit.
- Baked the head flat
- New valve seals
- Surface the head
- Cleaned the head
- Cleaned the block and crank
- Honed the cylinders
- Polished the crank
- Surfaced the block
- New Rings
- New Main and Rod bearings
- New frost plugs
- New gaskets
- New crank keyways
- Several new molded rubber hoses
- Green truck shifter gasket & shifter bushing
- HKS MHG
Had to junk the cams that were in the engine, they are scored badly from debris in the oil. Luckily I had 2 full spare sets. The crank that was in the engine was dead as well, the keyway slot was destroyed. Luckily I had a spare crank, too. :)

anything you think would depict a rebuild of your engine, say the camera panning for like 5 secs over all the parts and tools all over the place, and then another 5 secs going like the opposite direction, over where the parts and tools used to be, and it pans right to the engine bay,
kinda like a before, pan this way ------> and the after <------pan that way and end with the engine complete.
thats just an example you could do what ever you want, i just want to get some engine footage into the video and you IJ, shaeff, suze, and grp A are all doing rebuilds, im still looking for other peoples rebuilds if the have a thread, but anything that you think would be worth describing your supra and the work you put into it. Know what i mean?
GrimJack
10-01-2005, 03:44 AM
Ok, I'll see what I can do for you.
GrimJack
10-02-2005, 02:00 AM
Steam cleaned the tranny today. What a difference!
GrimJack
10-02-2005, 02:03 AM
And then did a whole shitload more assembly. Right now I am SO sore and tired it's not funny - 14 hours of work on it today. Some of which, admittedly, was driving around to get bits and pieces, or taking the tranny to the shop to steam clean 15 years of muck off of it.

Took some pics of the engine bay as it sits - I'll clean it and take another picture or two after it's done.
GrimJack
10-06-2005, 02:16 AM
And then I did a bunch more work. Picked up 4 sizes of wiring loom and replaced all the loom on the engine wiring harness, and after finishing that, plugged it into the motor, bolted on the upper intake manifold, and spent another 6 hours on assembly.
Then I took some more pics for my dedicated fans, of course. ;)
GrimJack
10-06-2005, 02:18 AM
And a few more pics, even.

grimjack changing your wires on the engine loom was a great decision in my opinion well done for being sesible and spending time on the important issues that get overlooked
:icon_bigg
Dirgle
10-06-2005, 04:02 PM
I think he means just the plastic loom covering the wiring harness. I know how fun that can be, I remember doing mine.
GrimJack
10-06-2005, 04:36 PM
dirgle is correct - though I found some issues with my knock sensor wiring, so I pulled off the plugs, fixed that up, covered it in heat shrink tubing, and put the plugs back on.
At the very least, it lets you put in some time inspecting the harness, so you'll know where faults may be and how hard they will be to replace later.
Dirgle
10-06-2005, 04:53 PM
When I did mine the entire harness was covered in electrical tape, which was a pain to remove all of it, clean the sticky gunk off it, and then rewrap it. I was wondering if you removed and replaced the tape or just stuck the wires back in to the new loom?
GrimJack
10-06-2005, 05:57 PM
Oh, I did most of the tape. Anything that was old and brittle was replaced.

Another relatively long night assembling the engine... with some NICE results. It is ready to go into the car, and hopefully this will happen tomorrow morning. A few things to hook up, a few things to bolt up, and I'm done.
Some more pics, of course...
GrimJack
10-08-2005, 01:44 AM
Oh, and then I couldn't leave well enough alone, so I installed some silcone hose. :D

wow.... ur block is like soooooooo clean, it looks fake lol
like the mk3 models that come with engines... the engine parts are grey... and toys... hehee
but looking awesome!!!! ;)
GrimJack
10-08-2005, 08:42 PM
Engine is in the car!
Still have to hook up a bunch of wiring, fill the tranny & engine with fluids, and then she's good to go.
I'll post some more pics of the engine going in later tonight - as long as I can still type by then, of course! ;)
CTsupra
10-08-2005, 09:06 PM
kick ass!
GrimJack
10-09-2005, 01:28 AM
Ok, now I am stinking tired. The car is close to running, but not quite. I still have to:
- mount the radiator
- mount and connect the fans
- run the rad hoses
- connect the heater hoses to the block
- connect the speedo cable to the tranny
- fix the clutch slave
- pull the wiring harness through the firewall
- hook up the ECU
- put the glovebox back together
- finish the shifter installation
- put the dash back together
- fill the engine with oil and coolant
- install the upper IC pipe
I'm tired enough that I started making silly mistakes, so it's time to call it quits for the day. Shouldn't take all that too long to get it up and running tomorrow, however.
Here's the promised pictures for the day.
GrimJack
10-09-2005, 01:30 AM
Here is what it looked like immediately after dropping it down onto the engine mounts and removing the hoist.
GrimJack
10-09-2005, 01:32 AM
And last but not least, a few pictures showing how far it's come from there today. This is what she looks like in the driveway right now - except that the hood is closed, of course. ;) I'm done for the night, I'll likely finish up tomorrow.
PS: Anyone care to sell me a spare set of skin for my fingers? I think mine is done for.
shaeff
10-09-2005, 03:02 AM
lookin' damn good, Grim! (sends spare finger waves via the intraweb)

Looking great Dave, it's hard to stop working on the car when it's so close to running again.
GrimJack
10-09-2005, 07:52 PM
Doh! Stalled for the moment. Seems my water pump didn't survive the pressure in the cooling system induced by the BHG. :( It was almost all together - everything but the upper IC pipe and the accordian hose, and I decided to put coolant in... well, the water pump leaks, rather badly, out of the holes top and bottom.

clean is one thing, but that. holy crap, it is totally spotless i dont think i could find a single droplet of oil on it.
just dont knock a quart of oil over with your elbow when you go to fill it up
never have i seen a block and oil pan that didnt have oil, thats just weird.

No chance of that, I already filled it with oil, and not only was I careful, I also used a funnel for the first time in over 10 years. :D
The engine is very clean, however, you can still find grime under the hood ... I think the pictures make it look better than it really is. Then again, maybe I'm just picky because I'm the one that put it together!

WOW.......Clean is an understatement. Its just like new. You do any 1JZ swaps GRIM?? I know that if my garage looked like that i would be sleeping in it. My supra already monoplizes half of the garage.

Thanks guys!
spipedong, no worries, I got the info from Adjuster, and we now have a very nice thread about it in the FAQ. You could likely post your text in the same thread!
turbo4toy, no 1JZ swaps for me - you're right, if my garage looked like this for more than 3 months out of the year, it would be my bedroom as well. The little lady gets growly when I decide to take the car apart.

Ok, finally took some pics of the finished product. It's been running now for almost three weeks, and I've finally got everything cleaned up - all the extra wires back into wiring loom, built a mounting bracket for the MAFT, and put in my new windshield washer nozzle to replace the one I snapped taking the engine out.
Anyhow, without any further mucking about, here's the pics!

Congrats again.
GrimJack
10-31-2005, 12:36 PM
The front of the car does look high - or at least the fender gap looks bigger. Combination of my ST springs and the fact that my tires are smaller in the front. :D
The only lightweight component I have in there is the flywheel, and it's pretty much in the center of the car.
Next time I take photos I'll do so on an empty tank of gas! ;)

I am back at this thread once again to use these pictures as a reference.
Grim, that is a hell of a job you did. I would not have imagined a new engine to be that...new looking.
As I already told you in AIM, those pics are quite helpful!
I once even used an attachment to verify with a buyer that we were talking about the same part. Well he complimented me, and of course I told him that it wasn't mine, but yours. heheh
With all those pics--and one can never have enough as a reference while building--this thread should be either in or somehow linked in the MK3 Supra Information/Reference section.
Well for my future searches, I will create a word that will bring me back here quick:
