Ok just to get this over with there is NO rod nock or nocking of the motor internaly ok anyways as im driving down the road just crusing not getting on it it runs fine but when i start giving it more than half throttle i hear like a vibrating noise coming from the passenger side on the back side of the motor it sorta sounds like an exhaust leak but theres nothing there until i get on it im kinda woundering if a vacum line came off or what but once you get up to around 7,500 rpms you can hear this "vibrating" noise pretty clearly but needless to say im back home but i limped it home affraid of what may happen if i push the motor more (ie driving slower shifting at 3,000 rpms) but does anyone have a clue what this problem may be tomorrow im going to be spending all day trying to fix the problem!

 

Broken motor mount maybe ? I'm not sure exactly what you are trying to describe.

 

A/C idler pulley can go bad on this motor, and it sounds like that sometimes. who knows, there are many things it could be.

 

well i fixed the problem i put the car up on some ramps this morning and fixed it it was a exhaust leak at the end of the header i have dc ceramic headers but i beleave at the acura dealer ship when they put a new motor in my car i beleave they striped out the threads in the header because i was able to back the bolt out with my hands but thanks anyways though for your alls help
