Why This Valve Cover Kit Solves the N55 Problem
Because the factory plastic cover ages worse than a sun-exposed dashboard.
This Kit Fixes:
-
Valve cover oil leaks
-
Oil in spark plug tubes
-
Burning oil smell from valve cover cracks
-
Rough idle from PCV failures
-
Misfires caused by vacuum leaks
-
Oil seepage onto turbos/manifolds
If your N55 is marking its territory everywhere you go, this is the cure.

Why Replace the Whole Cover (Not Just the Gasket)?
Because your N55 valve cover is already warped.
Replacing just the gasket is like putting a Band-Aid on a cracked oil pan.
A full replacement ensures:
-
Proper PCV function
-
Correct crankcase pressure
-
No more oil vapor leaks
-
Smooth idle
-
Better long-term reliability
Who This Upgrade Is Perfect For
-
BMW owners tired of the oil smell
-
DIY mechanics doing preventative maintenance
-
Anyone with N55 misfires caused by oil intrusion
-
High-mile turbo BMWs
-
Drivers who prefer reliable boosting, not leaking

I usually don’t leave product reviews, but this product was so bad I had to so.I ordered the aluminum version for my E70. Inspected it before installation and everything seemed fine despite the poor packaging it came in. Went ahead and professionally installed it. One day later and the car started throwing various air plausibility related error codes after a scan. A quick inspection of the valve cover showed that it had developed a hairline crack that was leaking oil all over my engine bay.Instantly uninstalled it and went with a OEM valve cover. Avoid this product, terrible quality & packaging. It’s cheap for a reason.
