MAHLE Engine Piston Set P/N:224-3503WR.040
MAHLE 224-3442 engine piston for the 1991-1993 Ford CF8000 6-cylinder 7.8L and other vehicles carries combustion pressure down to the connecting rod. The piston rides in the cylinder bore and holds the rings that seal that pressure and control oil.
Engine knock, blue exhaust smoke, rising oil use or low compression can mean worn pistons. Worn rings, scored cylinder walls and leaking valve seals can be behind the same signs, so find the cause before you buy pistons.
This piston fits the 1991-1993 Ford CF8000 6-cylinder 7.8L, the 1991-1993 Ford F-800 6-cylinder 7.8L and the 1991 Ford F-700 6-cylinder 7.8L. That 7.8L six-cylinder takes six pistons.
