Grinding noise from engine.

I was hoping maybe you guys could steer me in the right direction on what may be wrong with my car. I have a 97 civic hx(automatic) and noticed the other day that when the car is in park and the engine is revved that you will hear a slight grinding noise from the engine when you let off the gas. It sounds fine when you increase the rpm's its only when you let off the gas that you get this sound. I have not noticed this while driving and the car has been driving well. Any ideas on what may cause this?

Could be the lashing of a timing belt. They should replaced about every 80,000. If it's overdue I would either check or get it checked out.

Hope this helps,

Bob

Thanks for the reply. Hopefully its not the timeing belt since Honda had me replace it at 60,000.

You might check the bearings on the front accessories (alternator,power steering,etc.). Also check your distributor near the base.

Use a long shank screwdriver or length of stiff hose (heater or something similar).

With engine running use the hose or screwdriver as a stethoscope to go around to each of the devices while you rev the engine. You can usually pinpoint noises in that way.

Hope this helps,

Bob
