## 🔌 Function

Seals valve cover 20725338 to the cylinder head, retaining lubricating oil and excluding water, dust and other contamination.

## ⚠️ Common Signs of Failure

-   Oil leakage around the valve-cover joint
-   Gasket hardening, flattening, cracking or tearing
-   Oil mist and dirt build-up on the cylinder head
-   Leakage after installation with the incorrect cover or production version
-   Oil contamination of nearby electrical or intake components

## 🛠️ Service Notes

-   Fit a new gasket every time the joint is disturbed — a gasket takes a permanent set once it has been torqued and will not seal reliably a second time
-   Scrape both faces back to clean bare metal, keeping the blade at a shallow angle so it lifts the old material without gouging the surface, and use a plastic scraper on aluminium castings
-   Check the faces for flatness, cracks and corrosion pitting, and make sure no old gasket, carbon or hardened sealant is left in the corners or around the bolt holes
-   Fit the gasket dry unless the workshop manual for your engine calls for a sealant, and then only the type it specifies — surplus sealant squeezes out into oil, coolant and fuel passages
-   Draw the fasteners down progressively in the sequence and to the torque given in the manual for your engine, and recheck after the first heat cycle where the manual asks for it
