Product Details

Features

  • Rubber-with-steel construction seals Oldsmobile V8 valve cover mating surfaces

Description

The Oldsmobile V8 Rubber Valve Cover Gaskets seal the mating surface between Oldsmobile V8 valve covers and the cylinder head to help prevent oil leaks. Rubber-with-steel construction at 3/16" thickness is built to match the Oldsmobile V8 gasket rail pattern, so bolt pattern and sealing surface must match your specific application for proper installation.

This gasket set fits the Oldsmobile V8 engine family across 5.4L/330, 5.7L/350, 6.6L/400, 7.0L/425, and 7.5L/455 CID. Sold as a pair, covering both valve covers in a typical installation.

Verify bolt pattern, sealing surface, and gasket material before installation, and replace worn gaskets during valve cover service or a fresh installation.
