ok so i have a B16a2 and did a valve adjustment, set the stock spec.

intake to .006
exhaust to .007

at idle is seems ok, but when i drive or rev the motor a little i hear a tapping
did a compression test and and got
c1 - 200 psi
c2 - 195 psi
c3 - 191
c4 - 198

could some help me find what the problem could be

thanks

 

recheck the adjustment nuts because u might have forgot to tighten them. Usually that is the issue - well for me that is.
