BMW valve cover gasket cost by engine
On most modern BMWs the plastic valve cover is replaced as a whole, because the gasket and the built-in PCV valve fail together. The price depends mostly on the engine.

B48 and other engines
We do not have enough owner reports yet for a B48 (330i, X3 30i, X1) valve cover range, so prices are still being collected. The B48 shares the B58 design (plastic cover with integrated PCV), so the B58 page is the closest guide to symptoms. For all leak points by engine see BMW oil leaks by engine.
FAQ
Is a valve cover gasket leak urgent?
A small seep is not urgent, but oil dripping onto the exhaust manifold can smoke and become a fire risk, and on some engines oil can reach the spark plug wells and cause misfires. Fix it when you see smoke, smell burning oil, or get a misfire.
Why do BMW shops replace the whole valve cover?
On the N55, B58 and B48 the cover is plastic and the PCV valve is built in. Covers crack and warp with heat, so shops usually replace the cover and gasket together.
Can I replace a BMW valve cover gasket myself?
The M54 and N55 are common DIY jobs with basic tools and a torque wrench. The B58 and V8 jobs take more time because more parts come off.
