Sealed Power Engine Piston Set P/N:H1546CPALR (Pack of 8)
Sealed Power H858CP engine piston for the 1997-2000 Ford F-150 V8 4.6L and other vehicles carries combustion pressure to the connecting rod through the piston pin.
Oil burning, blow-by or a ticking noise on a cold engine can point to worn pistons or rings. These signs alone do not prove the pistons are at fault; worn valve stem seals can burn oil too.
It is listed for a wide range of Ford, Lincoln and Mercury models, including the 1997-1999 Ford F-250 V8 4.6L and the 1996-1998 Ford Mustang V8 4.6L, and a V8 4.6L takes eight.
