That's an expensive piece of rubberized plastic... My BMW service manager said that the gasket doesn't typically need to be replaced as suggested at the 6k mile service interval; depending on your miles, perhaps it's time for new...Valve cover gasket...
Inspect, clean and replace if needed.
Its $350.00

I second this.I haven't experienced any leaking; perhaps, maybe check that the valve cover is properly torqued and the gasket is in good shape.
I agree with Scott has anyone been in at the tappets recentlyHello everyone ,Has anyone ever had a cylinder head leak ,it is located below the cylinder,and What's the solution?
Thankyou!

I recently adjusted my valve clearance and practiced what I preached here.I second this.
I would also take the gasket off and do a thorough cleaning with some dishwashing soap (the degreasing type) to ensure that ZERO oil residue remains. Even use some brake cleaner on a shop towel and clean up the cylinder head surface to remove any oily residue there as well. The gasket should not be slippery to the touch after degreasing, it should "grab" your finger like a tire tread if you drag your finger across the surface.
Then, with both surfaces 100% oil-free, tighten the gasket back down to factory tolerances...maybe a "little" bit more snug but not excessive.
Take care of the problem now and you'll save yourself a headache later

This has been my experience.Did you just do a valve service? ... mine drool just a bit after a valve service .. I think it is oil that 'hides' a bit around the gaskets after and then eventually gravity makes it collect down there ... I wipe it off and it doesn't come back ... just my 2¢
