A Permanent Fix for a Known S65 Engine Weak Point

The MMX S65 VANOS Aluminium Covers are a precision-engineered solution to one of the most well-documented issues on BMW’s legendary S65 V8 engine. The original BMW plastic VANOS covers are notorious for cracking, loosening, or even falling off completely — an issue that can lead to catastrophic internal engine damage if debris enters the oil system.

MMX has developed a true replacement cover, machined from aerospace-grade 6062-T6 aluminium, that eliminates this risk entirely. Designed as a direct-fit replacement for the OEM plastic components, these covers provide lasting reliability and peace of mind for all E9X M3 owners.

Why Replace the OEM Plastic VANOS Covers?

The S65 engine’s plastic VANOS covers deteriorate over time from heat and vibration. Once compromised, small plastic fragments can enter the oil pickup, causing oil starvation and serious internal damage.
BMW’s only official fix is a complete VANOS unit replacement — a costly and unnecessary repair when a durable replacement cover can solve the issue permanently.

The MMX Solution – Engineered for Strength and Longevity

MMX’s upgraded VANOS covers are CNC-machined from high-grade 6062-T6 aluminium and finished in hard black anodising for long-term durability and a clean OEM-like appearance.
Unlike other aftermarket alternatives, the MMX design keeps the internal VANOS springs fully enclosed, maintaining proper function and preventing contamination while delivering a perfect fit.
