Key features
- OE replacement style
- Black plastic cover
- Designed for the 2.5L 4-cylinder engine
- Grommets sold separately
Grommets and cover installation
Grommets are the rubber seals that sit in the cover and hold the bolts or fasteners in position, and they are usually the first part to show age. A cracked or flattened grommet can let oil pass around the fastener even when the gasket is sound. Since they are sold separately, buy them before starting the job so the cover is not left off the engine.
Before installing, check the cover for warping, cracks at the mounting points and an intact sealing surface. Wipe the cylinder head clean and make sure no old gasket material remains. After the first few drives, look for seepage around the bolt holes, as heat can settle the seals a little.
- Replace grommets that are cracked or flattened
- Check the cover for warping
- Clean the head surface before fitting
- Recheck for seepage after the first few drives
