Damn, and when I did a compression test on my 2003 Type-S with 40,000 miles on her I got:

125
120
125
130

But the car runs fine....makes me think I might have done something wrong.

Sounds to me like you didnt disable your fuel pump. I Just pulled the ECU fuse.
What? I wasn't aware that you had to disable the fuel pump and/or pull the fuse to the computer when doing a compression test. I never heard this from anyone else when I was asking about the test.

Why would not disabling my fuel pump or pulling the ecu fuse cause my numbers to be so low?

take care of ur engine and ye shall reap the rewards.


exactly.. The only reason I can think that I have such perfect compression is I baby the motor. It never gets ran cold. Its always wamred up to full operating temp before its driven. 75% of ring wear is done before the rings get a chance to fully expand.

and the 2500 mile old changes.

:thumbsup: for taking care of k20's
