Product Overview
A cracked plastic cover, failed integrated crankcase ventilation system, oil in the spark-plug wells, smoke from oil on the exhaust, or persistent gasket leakage can bring an N54 owner to this repair. The aluminum cover replaces the complete upper cover rather than only resealing a warped or damaged original.
N54 and N55 covers are not interchangeable. Confirm engine code, breather layout, bolt pattern, sensor openings, and part number before disassembly.
Key Features & Performance
- Aluminum replacement for the N54 valve-cover application
- Provides a rigid sealing surface for the included-style gasket system
- Addresses cracks, PCV-related cover faults, and oil leakage
- Covers multiple N54-powered BMW chassis

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Production date, engine type, transmission, trim, serial number, and previous repairs can change fitment. Compare the original part, mounting points, dimensions, connections, and listed reference numbers before purchase.
Frequently Asked Questions
Q: Will this fit an N55 engine? A: No. This listing is for the N54 cover layout.
Q: Can a cracked cover cause a vacuum leak? A: Yes. The cover and its PCV system can create unmetered-air and crankcase-pressure problems.
Q: Should I reuse the old gasket? A: No. Use a new compatible gasket and seals.
Q: What number should I match? A: Cross-check 11127565284 and the complete N54 cover configuration.
