Compression test time.

mufflerbearing · « **Reply #17 on:** April 25, 2008, 02:59:13 pm »

clearance on 2 of the intake valves is a little big... just out of spec, but that wont effect compression. ill change them, but not yet.

i got # 3 and 4 done but couldnt fit the adapter between the pump and #1 and 2 so ill have to figure something else out. looks like i might have an adapter for the injector that im gonna have to try out and see if it works.

so far i have about 540psi at 3 and just a hair under that in 4.

so, half of the motor is good, anyway...

im getting ~500psi across all 4 cylinders.

when i pulled the 2nd injector, its tip was covered in oil...

any ideas? valve stem seal?

try bumping the timing down to 0.90

Did you replace the heatsheilds after the compression tests?

ordered a set.

also have valve stem seals on the way and the special tool to press them in without removing the valve/head.

we'll see how it all goes next chance i get to work on it
