Dorman - Autograde Engine Camshaft Plug P/N:555-055
Seal the rear camshaft bore and keep engine oil contained with the Dorman - Autograde Engine Camshaft Plug 555-081. This steel cup expansion plug drives into the camshaft bore to close off the passage and hold back engine oil, and it drops in as a direct-fit replacement across a wide range of classic and heavy-duty Chevrolet and GMC applications — including the 1988-1998 Chevrolet C1500, 1988-1998 Chevrolet K1500 and 1995-1999 Chevrolet Tahoe. See the Buyer's Guide tab for the full list of applications.
The plug seats by press-fit into the bore — it is driven in, not threaded. If a worn or leaking original camshaft plug is the source of oil seepage at the rear of the engine, this replaces it. Diagnose the cause of any leak before installing.
