11421713838 / 11421722513 Oil Filter Housing Check Valve for BMW M50, M52 and M54
This reinforced oil filter housing check valve is designed for BMW engines using original part numbers 11421713838 and 11421722513. It replaces the worn internal valve inside the oil filter housing and helps prevent oil from draining back into the sump while the engine is off.
When the original plastic valve wears out, the oil filter housing may empty overnight. This can cause delayed oil pressure after startup, metallic clatter during cold starts and temporary oil starvation during the first critical seconds of engine operation.

What This Part Does
The oil filter housing check valve keeps oil inside the filter housing after the engine is switched off. This helps maintain oil availability for the next startup and reduces the risk of dry-start conditions.
In many BMW M50, M52 and M54 applications, BMW supplies this valve only as part of the complete oil filter housing assembly. This standalone reinforced valve allows targeted repair of the failed internal component without replacing the full housing.
