My compression test

[alundra]

So, how do you guys run on >200bhp, any "cooling advice"?

Yes turbo area create an hot spot between 3rd and 4th cylinder.

but when i got hold of a good head from the silviagod and had it sorted at AMT engines , it never blew again, it had the mig wired bock and ran 32psi with no probs.

mig wired bock

mig is welding right? Any pics?

yes 3 is the hottest
You need to drive it a bit more incase it is just fluids in the exhaust. If not i would say its fuct



Check that residue out and determine if it is definately water or oil. If it doesnt clear and you say the turbo is fine then that head is going to have to come back off.
180 degrees out
You should fit a 13 row oil cooler if you want to use it on the track, Also foam fill the fuel tank or never let it go below 1/4 of a tank

I forgot to say fitted some exhaust band on manifold.
Ok guys, i'll check and tell you.
I thought that stock oil cooler was enough and don't run under 1/2 tank.
Take care of your car

Yeah I've noticed on the ET and DET that number 3 gets buggered the most, not sure if its heat, difference in compression or fueling or whatever that causes this if I'm honest

Why will 3 run any hotter due to the firing order?

Sorry i cant teach you anything as it doesnt make any sence.mwahaha I was using the quick reply as a notepad template and did not delete all the text.


Nearly all headgaskets on the et engine either go between cylinder 3&4 or they go on the water ways as they have gone rotten.3 and 4 exhaust ports and manifold sections definately get the worst of the heat and possibly backpressure turbulance from the turbo.

I holed a piston on the et once and that was number 3

Only other reasons could be that the coolant is at its highest temperature at the further end of the block. its all speculation.


Im sure that an air to oil cooler is the way to go.
