Detailed Description

This Apex valve cover gasket set is intended for service work on compatible Cadillac and Oldsmobile engines where the valve cover seal has hardened, leaked, or been disturbed during maintenance. The listed fitment covers 1993-1999 Cadillac Allante, DeVille, Eldorado, and Seville applications, plus 1995-1999 Oldsmobile Aurora applications, all noted with grommets and spark plug tube seals. Use AVC368S when replacing the valve cover sealing components on these vehicles and when restoring proper sealing around the top end of the engine. AVC368S is a practical replacement choice for Cadillac DeVille, Cadillac Eldorado, and Cadillac Seville service jobs where oil control at the valve cover is needed.

What It Is Used For

  • Stopping oil seepage from the valve cover sealing surface.
  • Replacing brittle or flattened gasket material.
  • Addressing leaks around spark plug tube openings.
  • Renewing worn grommets during valve cover service.

Installation Notes and Tips

Clean the sealing surfaces thoroughly before installation and inspect the valve cover for warpage, cracks, or residue that can affect sealing. Follow the vehicle service procedure for torque sequence and recheck for leaks after the engine reaches operating temperature. Confirm the application by year, make, model, and the listed grommet and spark plug tube seal notes before ordering AVC368S.
