I have a d16y8 and I adjusted the valves some of thrm were loose. Someone accidently put 20-50w synthetic oil in my civic. I did the motor flush ran the car for 5 mins as instructed. Still getting a valve tap it put a screw driver up to the head of the motor and then to my ear and it sounds like clyinder 4 exhaust side is still noisy and suggestions?O yea its a boosted y8

 

bump

 

bump, been curious about tapping valves too

 

Are you sure it's not your injectors? Honda's are noisy in the head, we gotta live with it.

 

Ill try to get a video tapped its definetly bad vavles i think I got 450 dsm injectors in it. Sounds like clyinder 4 exhaust side.
