BMW Serpentine Belt Crankcase Seal Cover Plate (Red) | N52 N54 N55 Engine | E90 E91 E92 E93 E60 E82 E87

Protect Your Engine From Catastrophic Failure Caused by Serpentine Belt Slippage

Protect your engine from costly damage with our upgraded BMW Serpentine Belt Crankcase Seal Cover Plate. This simple yet essential part blocks the front crankcase access port — a common failure point that can allow serpentine belt fragments to get sucked into the engine during belt failure.

If your belt snaps and enters through this port, it can destroy the timing components and require a full engine teardown. Our cover plate is designed to seal off that opening completely, offering peace of mind and long-term reliability.
