BMW m2 oil filter housing / thermostat flow direction

F87source · 12-19-2018, 04:42 PM

Hey guys, just curious if anyone had schematics or BMW official diagrams showing oil flow direction through the oil cooler loop and which lines were the inlet and outlets on the stock oil filter housing.

I wanted to integrate this high flow 75L per min thermostat to better get oil flow to the oil cooler, plus it'll allow me to choose a specific oil temp before it opens up.

Let me know if you guys find anything, I checked newtis, realoem and nothing. I found someone who did it for the E series n55, but I would like verification for the m2 before I mess something up doing this.

Thanks guys!

I'm guessing no one?

I guess if worse comes to worse I could always buy a short piece of clear tubing and zip tie it to an AN fitting and observe oil flow.

I'm going to assume either no, or very minimal flow will come from the out port of the housing when the oil is cold, and nothing should come from the inlet side. But when it warms up I should hopefully have a clear indication of flow.

Please correct me if my assumption sounds off, thanks again guys.
