i just ran a compression test on my friends 01 k20a2 and the numbers where

cyl#1- 190 cyl#2-165 cyl#3-190 cyl#4-190

what gives?? rev limiter is at 8500. mis shifted a couple of times. but i think that would have hurt more than 1 cylinder. any ideas?

 

possibly bent valves

 

thats what i was thinking of

 

for sure a valve probalby the exhaust side i had the same problem on one of my prelude's a while back
