MITZONE N55 Engine Valve Cover Kit for BMW 3.0L (2010–2019) — Includes Gasket, Spark Plug Seals & Oil Cap

MITZONE N55 engine valve cover kit is a complete replacement assembly — valve cover, gasket, spark plug seals, bolts and oil filler cap — built to match the fit and sealing needs of many BMW N55 3.0L and related engines.

This MITZONE kit is designed as a full-service replacement for worn or leaking valve cover components on numerous BMW models that used the N55 and related engine families between 2010 and 2019. The package includes the valve cover itself plus a new gasket, three spark plug tube seals, a set of mounting bolts and a fresh oil filler cap so you can restore a proper seal and simplify installation in a single purchase. Materials and dimensions are manufactured to meet or exceed typical OE standards for strength and sealing performance.

Will this valve cover fit my BMW model?

The kit lists compatibility with a broad range of BMW models that used N55 and similar engines across model years roughly 2010–2019. Confirm fit by matching your vehicle’s engine code and part reference (Part# 11127570292) against your VIN or current valve cover before ordering. When in doubt, consult a parts specialist or provide your VIN to verify match.

• Compatible with many 3.0L N55-equipped BMWs including 335i, 535i, X3, X5, X6, 740i and others
• Includes the listed part number to cross-check with dealer or vehicle records
• Intended as a direct replacement for vehicles using the referenced valve cover design

How does this kit improve engine sealing and maintenance?

Replacing a worn valve cover and its sealing components stops oil seepage that can foul coils, spark plugs and nearby sensors. New gaskets and spark plug tube seals restore tight sealing surfaces, while fresh bolts and the oil cap ensure even pressure and prevent leaks under normal operating conditions.

• New cover and gasket reduce oil leaks and protect ignition components
• Spark plug tube seals prevent oil intrusion around plug wells
• Supplied bolts and oil cap simplify installation and restore factory clamping

What’s included in the MITZONE N55 valve cover kit?

The kit is delivered as a complete bundle so you don’t need to source small parts separately during installation. Everything required to replace the valve cover sealing assembly is included, saving time and reducing compatibility guesswork during a repair or service interval.

• One new engine valve cover molded for the N55-style cylinder head
• One valve cover gasket, three spark plug tube seals, new bolts, and an oil filler cap
• Parts intended to match OE form and function for a straightforward swap

Is installation difficult and what should I inspect during replacement?

Installation typically requires moderate mechanical skill and basic tools; it’s commonly performed during routine service or by a professional technician. Clean mating surfaces, torque bolts to manufacturer specifications and inspect surrounding components like ignition coils, PCV connections and nearby wiring for heat or oil damage.

• Recommended: clean mating surface and replace seals in a clean workspace
• Torque bolts to OEM specs and check for proper oil cap seating
• Inspect coils, wiring, PCV hose and nearby sensors for oil contamination

Who is this for: This MITZONE kit is aimed at BMW owners, independent shops and DIY mechanics dealing with oil leaks or preparing for routine engine maintenance on N55 and related engines. Choose this kit if you need a full valve cover replacement package with seals, bolts and an oil cap included to restore proper sealing and reduce future maintenance downtime.
