1993 Oldsmobile Eighty-Eight Piston slap
I have one more concern about my 3800. Whenever the temperature gauge reads 200 degrees, my engine begins to make a slapping noise from cylinder 1 or 2. When I drive it cold this doesn't happen, but after a long drive it makes that noise at idle. Is this piston slap or a serious problem? I'll post a video with sound so you can understand my situation.
