I have a 2000 Grand Am with a 2.4l twin cam engine. It was making a loud tapping sound all the time. So I replaced all the gaskets, the head, the cams, timing gears, timing chain, and rod bearings, but it's still making the loud tapping sound. The only thing left I could possibly think might be wrong is the crankshaft. Could you please give me some advice? Thanks.

It may be the cam followers have this looked at professionally so you dont' waste your money it could be piston slap which doesn't hurt anything just makes noise.
