Valve Cover Gaskets: the seal that keeps oil off your engine and out of your driveway

Valve cover gaskets sit between the valve cover and the cylinder head, sealing the top of the engine where oil splashes around the cams, rockers and springs. When the old one hardens or cracks you get oil weeping down the block, oil pooling in spark plug wells, and that burning smell off the exhaust manifold. Fitting a fresh gasket during a valve adjustment, a cam job, or any time the cover comes off is cheap insurance against a mess and a misfire. It is a straightforward job with the right part in hand.

What ThreePiece stocks

This category holds 9 in-stock products across 3 brands: Cometic Gasket (6 of the sample), QuadBoss (2) and Athena (1). Current prices run from $33 to $70, which is the live range for what is on the shelf now rather than a fixed quote. Every listing carries fitment data, and coverage spans model years from 1988 to 2023.

The mix covers cars, ATVs and UTVs. Named makes include Dodge, Honda, Nissan, Ford, Polaris, Can-Am and Lincoln, with specific vehicles like the Dodge Viper, Nissan RB20/RB25/RB26, Dodge Hemi, Polaris ATP 500 and Can-Am Commander 1000. As examples, the Cometic 92-02 Dodge Viper .125in gasket sits near the top of the range, the Cometic Mustang, Focus and MKZ valve cover set covers a shared 2.3L/2.0L platform, and the Athena Honda CRF 110 F gasket serves the small-bike side. For powersports, the QuadBoss Polaris ATP 500 gasket and the QuadBoss Can-Am Commander 1000 gasket are the lower-priced end.

How to choose

Start with exact fitment - engine and year, not just the make. A gasket cut for an RB26 will not seal an RB20 cover, and a Honda B16 part is not a CRF 110 part. From there the trade-off is mostly about what you are working on: single-application powersports gaskets from QuadBoss come in at the low end for one machine, while a Cometic multi-fit set can cover a whole platform. If you want the cover off once and sealed for the long haul, buy the correct application the first time rather than reusing a tired gasket.

What else you need with it

Since the cover is already off, it is worth looking at related seals and service parts in the same Engine Components section. Consider head gaskets and full gasket kits if you are going deeper, plus oil filters for the fresh oil that follows the job. If you are rebuilding, pistons, bearings and fittings live nearby too.
