After replacing all aluminum oil filter housing, there was a leak coming from the new part’s mating surface. Need to remove and install a Genuine BMW part.
_________________________
Once the Genuine BMW oil cooler and oil filter housing was replaced. We filled with coolant and two more leaks revealed themselves. The coolant hose fitting on the thermostat houing is leaking. The hose is brand new, not leaking from hose. Also, we found a second leak directly on the water pump plastic pressure relief fitting. Needs a new water pump and thermostat.
