Hello.

I have a 86.5 with automatic transmission that has this strange noise that only happens at the following situation:

When the car is at low speed and low RPM and on the 4th gear (automatic transmission) and I press on the gas hard but not as much for the kick-down to engage, the engine has this loud clak, clak, clack... noise on the passenger side that does not seem to be RPM dependent. As the RPM increases it disappears and the engine sounds great. If I accelerate slowly, no noise. When the car idles I can hear some clicking on the engine, but nothing too loud. Car runs great and accelerates fine at high RPM and WOT.

Stick lifter? Or injector? Any help is appreciated.

Thanks.

Are you sure it is in the engine? Could it be an engine mount problem that is allowing the engine to move under high torque reaction conditions resulting in exhaust or an engine part to hit the body?

Some clicking at idle could be related or not. Try and identify where the idle clicking noise is coming from using a stehascope or a hose held to your ear on one end and various locations on the engine with the other end.

Another possiblity is an exhaust leak at one of the exhaust ports. That can sound partially RPM-dependent, but can seem to go away as RPM goes up.
