What was your compression after a rebuild?

[Batty200]

Okay, heres the update> I did the leakdown test, by the way the engine was at operating temperature. It apears that the head is not leaking at all or too little to detect which Im kinda glad about as Ive paid...... damn ... alot for the work done to it. Its losing compression past the piston rings because it was blowing alot of air out of the crankcase when I presurized the cylinders. The headgasket is fine, no air was lost into the cooling system. I did discover my oil cap leaks though . Oh I redid a compression test with a different tester and it read a little bit higher it was 137 137 127 137. And the vaccum was -20psi at idle, according to my boost gauge.

Could you please PM me instructions on how to build a leak down tester? I would like one for myself.

If all you are doing is pushing air into the cylinders then I know how to do that but if it actually has guages and tells percent I am interested.


Thanks

I finish to built my stroker engine and now after 50 miles i got 180 psi on my 4 cylinders on my 4g63 turbo
