I've got an '88 Trans Am, 305 TBI. The heads belong to the engine and there have been no mods to the block, cam, crank, or heads.

At idle my car has a fast, rythmic clicking sound on the passenger side head. The click continues, though faster, as the engine revs. Could this be valve / piston slap? It only happens on the passenger side head, and it is NOT an exhaust leak (as I checked for this as the car ran). I'm going to get video / audio tomorrow after work.

If it is piston slap, how do you fix it? What causes it? It's definately a clicking sound, which made me think of the valve train instead of the pistons themselves.

Thanks!
