I've had a pretty nasty oil leak for some time now, at least a quart a month and I don't drive much. I figured out it was the oil filter housing/gasket, which apparently is pretty common, per my local BMW shop. I'm putting in a new radiator this weekend (which hopefully won't be too bad...), so I figured what better time to tear into the oil filter housing leak issue, than when I'll have a ton of room to do it! Has anyone done this repair before? The housing itself is ~$200+, but I don't think I actually need the whole housing, only the small inner gasket...which is $4.85. My BMW shop said something about the flange that butts against the block possibly warping, so it's best to replace the housing as well. However, their job is also to make $$$, so I don't see that being the case. Any tips on the job itself or the housing vs gasket replacement would be great
