PISTON SLAP IN 98 2.5L ENGINES

 

I don't have official wording on this, but the problem and solution are as follows:

 

A redesign of the piston "skirt" (the metal ring that sits above the piston head and surrounds the piston shaft) to lighten weight and improve performance has left the skirt too short and the piston may travel excessively from side to side, especially when cold. The symptoms include a ringing/tapping sound that doesn't go away completely when the engine is warmed up, and gets worse with age. The solution is to replace the entire short block (most of the engine) and pistons with redesigned ones. If you can convince the dealer that this is your problem, they're usually pretty easy about doing the work.
