for some reason no 3 piston goes fooked on the late 90's cars - dont know whether its a fault in the block causing it to knacker the piston or what, the earlier ones are ok, as are the later 2001 onwards models, around 96 to 2000 through are the ones u need to watch for, they dont even need the boost turning up to do them in, they just seem to loose compression and die on no 3
