Oil Leak - Oil Filter Housing/Oil Cooler Gasket Replacement - BMW 330D E90 2009 N57 + Coolant Change

In this video I fix a major oil leak on this 2009 BMW 330D E90 fitted with the N57 3.0 straight six diesel engine. This oil leak had been an MOT advisory for several years. The engine under tray had become saturated with oil and this was dripping onto the driveway and leaving oil patches.
I replaced the engine oil filter housing/oil cooler gasket and o-ring, also carrying out a coolant change in the process, using genuine BMW antifreeze concentrate and de-ionised water.
The battery was disconnected as the live (positive) connection to the alternator was removed. This job also involved removal of an intercooler pipe.
The cooling system was bled and the oil level reinstated, using 0.5 litre of 5W30 Quantum oil.
Parts were genuine BMW from the dealership. Prices plus VAT (TAX)

Wonderful! Gonna do the same work next week. But is it needed to empty the coolant when I change the Oil filter housing?

[@autoknight747]

Removing the housing opens up coolant and oil galleries so it is optimal to drain the fluid level below that point. It is important not to allow oil to enter coolant passages and vice versa.

Was there oil in coolent tank

[@autoknight747]

@@markfarrier1711 No. Oil and coolant had not mixed, it just had the bad external oil leak.
