Thread cleaned up. Keep this thread on topic from here on out. If you aren't giving sleepydsm opinions on his results then shut up and start your own thread. If you want to know how to compression test your own car then start another thread addressing that issue on your own and we will be glad to help.

Wasn't that motor just rebuilt when Blake owned it. (by shindley)

Blake didn't mention it to me? I probably screwed it up though.

It isn't *that* bad except for #1. The engine has to be at full operating temp to get accurate results. Drive the car around for 20 mins and try it again.

yah we def didnt do that. we'll try it again and post up new ones.

Glad someone said something about that, it should'd do anything to even out the cylinders though which is actually the bigger issue. Like Shane mentioned, the wet test is somewhat tricky with any dish to the pistons. there is typically .300 above the ring to the crown that oil can ride in without going into the center, but it is a bit tricky to get it in there accurately. I have a few tricks to do it, stop by the shop and I can tell you how if you like.

I will let you know what kind of difference lower compression makes. I will be testing on a car with (4-1) 140-140-130-90.

[sleepydsm]

Sounds good. I am redoing the compression test tomorrow, at operating temp just for shits.

SLEEPYDSM's new test numbers:
1-120
2-130
3-150
4-150
Rings? Headgasket? Is his next step a leakdown test?

Run 'er til she blows! It is probably valve seals or rings though.

[Kracka]

Ehh, I've seen much worse. I'd leave it and continue driving it as it sits unless you want to be super picky. Boost makes up for compression loss...

ASS (inside joke)
