Compression Test Results 2

blageo23 · 06-08-2005

I did a compression test on my car yesterday and it came out:
#1-145
#2-147
#3-148
#4-145
I just did a 6Bolt swap with topline rebuild kit,i forget what compression pistons they are.(8:1) Is that a normal results? There is about 200 miles on the rebuild. and the car was warm but maybe not running temp. I know that they are sapose to be what 10% of eachother or something, but I would like to know if this is normal.

If the motor was just rebuilt with 8:1 pistons, that is low. Did you do the valves as well?

I did nothing to the head. when i bought it the guy told me it was rebuilt like 3000 mile before i bought it. I dont know if that is true but it looked clean and good from what i could tell. but im a narnar with that stuff so im not 100% sure.

Maybe the rings aren't broken in yet. That is pretty low though.

Put a few thousand more miles on it and check it again at full operation temp. Make sure to keep using conventional oil during break-in.
