I have a 2009 BMW 328i and I've noticed some oil leaks. Does anyone know what the problem could be?


Also, my car idle when it's not in motion but it doesn't do it all the time just here and there.

looks like it's coming from the OFHG (oil filter housing gasket)

Common oil leaks on the BMW E9x series: Oil filter housing gasket (you got that), valve cover gasket, and oil pan gasket. Either the valve cover gasket or oil pan gasket is the likely source of oil on the belly pan.

Note that oil from the oil filter housing gasket leak can get on your serpentine belt and cause it to fail catastrophically. In some cases, the belt has shredded and been pulled into the engine via the crankshaft pulley and seal. In some cases, the shredded belt has plugged the oil pump suction screen which can cause low oil pressure and wiped crankshaft bearings. The point here is that you don't need to delay fixing that oil leak and replacing the belt.

Not hard to DIY

If you have the tools, neither the Oil Filter Housing Gasket, or the Valve Cover Gasket are hard to replace, it just takes some time.

Make sure if any oil got on your coils that you clean them thoroughly.

Make sure the O ring around the filter housing is properly seated. The part you can see in the first pic looks fine but it's easy to get it nipped out a little bit and when the oil is under pressure it will pour out.

My valve cover gasket is leaking slowly. Not too concerned. Just add oil when you need to. Itís like an oil change 😁
