Seal the rear camshaft bore and keep engine oil contained with the Dorman - Autograde Engine Camshaft Plug 550-027.

See the Buyer's Guide tab for the full list.

  • Concave steel cup: a steel expansion plug engineered to match the fit and function of the original piece on the listed applications.

  • Press-fit install: driven into the camshaft bore opening — not threaded or bolted.
