I have a 2000 Civic DX with a D16Y7. It has this wierd tapping sound at steady throttle in the 1700rpm to 2300rpm with a steady engine load. If the the rpms are higher or lower the sound goes away. If throttle input changes, the sound goes away. I thought I might need my valves adjusted so I had that done and the sound is still there. Does anyone know what might be causing this? I hope it is just the head and not some other part of the engine.

 

just blow it up, then itll stop making noises

 

haha, that would be fun, but then how do i get to work

 

maybe its your tranny

 

thats exactly what i was thinking...

does your car make the sound at idle? If it does, put your car into gear and see if it still makes the noise. Also put the car into a gear and listen for a noise during deceleration(don't neutral break just let off the throttle).

 

I get no noise at idle, even when it is idling at 1500rpm in the morning. I will try to listen for it during decel next time I take a drive. What part of the tranny could cause it make that noise? Syncros, clutch, flywheel, gears themeselves? I have been getting a few unwarrented grinds lately going from first to second at random rpms.

 

any honda techs on here that have had people come in with the same prob?

 

ok, lets get this thread goin again because i have the same problem and cant find shit about it. Except i have a y8

 

rod knock, kill it.
