Oil Filter Housing

The oil filter housing is pretty self explanitory; It holds the oil filter assembly. Not only does this provide a small amount of cooling but it makes the filter much easier to service.

If your M50, M52, or M54 engine takes a few seconds to build oil pressure after sitting, there's a good chance that your factory oil filter housing drain back valve has failed. Over time, the factory plastic check valve degrades, allowing oil to drain completely out of the housing and back into the oil pan while sitting. Every cold start essentially becomes a dry start, resulting in a loud ticking noise and causing unnecessary wear on your engine's internals.

Unfortunately, BMW does not offer this check valve as a standalone part, forcing you to purchase a costly, complete oil filter housing assembly just to fix one failed plastic component. Thankfully, our team of BMW enthusiasts took note of this common failure mode and designed a permanent, cost-effective fix.

Our Billet Oil Filter Housing Drain-Back Valve is designed as a direct-fit upgrade for your factory oil filter housing. CNC-machined from high-strength billet aluminum, this upgraded valve restores positive sealing to keep the oil filter housing fully primed. Maintaining this hydraulic prime ensures rapid oil pressure stabilization upon startup, directly mitigating dry-start bearing wear and top-end lifter starvation without requiring the purchase of a complete OEM housing assembly.

Includes gaskets and hardware to replace both oil filter housing gaskets. Over time gaskets become dry and brittle allowing oil to leak in your engine compartment. Replace this gasket and stop having to top off your oil every month. A common source of leaks on the N54/55 is the gaskets between the the thermostat plate and filter housing, and also the filter housing to engine block.
