7M's have a bad habit of cracking the block between the Headbolt Holes and the steam holes after being surfaced if the holes aren't chased and then chamfered during a rebuild.
The idea of a chaser is it doesn't remove material just the crap in the hole, a Tap will do the same thing if you're...
LMAO that it does!
I remember forgetting to plug it back in after working on the car and driving around on LPG till it ran dry switching to Gas and NOTHING other than a nice idle ;)!
Very frustrating till I figured it out!
Probably find that they're the exact same thing as "Keenserts" it's just a brand name thing like "Helicoil" and "Recoil"
Why don't the Dak Dak guys like them?
(The noise VW's make ;) )
It sounds like your mate is talking about "KeenSerts" they have locking pins to hold them in once in place, HeliCoils achieve this with the cut off end preventing them unscrewing.
Never had a problem with HeliCoils if they've been installed correctly.
Jimi: Throw a new Filter on it after 100 miles top up the Oil then run that for 500 and change it then.
Damn good news that it's right this time! :D
(I'll just about bet the old crank was 20/20 or greater on the undersize!)
All motors have some blowby it's just the way they are as you need an end gap on the rings.
You should run a hose from the can to the stock PCV fitting.
I'm really not getting this facination with running just a can or those little filters on the cam covers.....
Unless the motor is...
Thanks JJ!
I usually don't post unless I'm sure of my info and as I've made remote filter adaptors in the past I was 99% certain this time but went out and checked just in case!
While 18x1.5 is close in TPI the Thread form is different between the 2.
The Toyota Adaptor thread is 3/4-16.
od on the fitting is .749 where as 18mm = .708.
(measured by me 5 minutes ago)
It's 3/4-16 there are quite a few Imperial thread sizes used by Toyota.
The Pressure sender and various plugs in the block are 1/8 th BSP I think this came about after WW2 as a lot of English designs were licence built in Japan which were then evolved into the motors we have today.
