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.

  • Steel cup expansion design: a press-in plug built from quality materials for dependable, long-lasting sealing.
  • Engineered to match the original: designed to install like the factory plug on the listed years, makes, and models.
  • Replaces a worn plug: a sound choice when the original plug is missing or has fatigued and started to seep oil.
  • Trusted support: backed by a U.S.-based team of product experts and over a century of automotive experience.

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.
