OFHG Leak Path

Bimmer_Engineer · 04-03-2020, 01:10 PM

So I know my OFHG is leaking...I'm wondering if anyone can speak to the leak path. Would it leak down the front of the block in the vicinity of the VANOS? I cleaned that part off the other day and I checked this morning and I can see some wet oil in that area...

If its not the OFHG then I suppose my VCG is leaking again...

Depending how bad the leak is it will leak down the front of the engine along the head gasket and can make its way down to the oil pan gasket. OFH is the highest component on the engine that will leak oil. Best to start with that and then clean it up again.

Mine leaked down the front and reached my water pump on the opposite side.
