Hi all,
About 6 months ago I bought a 2006 e92 335i Auto with 165,000km. Been driving it with no issues, albeit with a misfire every now and then at idle - suspect an intake valve clean is needed. I drove it from Wellington to Auckland with no issues.
The issue is that I've noticed it drops a bit of oil which I'm trying to fix. It leaks about a drop or 2 every time it's parked. I've taken all the covers off (multiple times now ?) and given everything a good clean. With everything mostly cleaned, I left it running (idling) for a couple of minutes while on jack stands to see if I could spot any visible sources of the leak. Judging from what I've seen (photos) it looks like it's leaking between the engine and the transmission, which could point to the rear main seal? Doesn't look like the oil pan gasket as I can't see any oil travelling along the pan towards the transmission. The oil pan gasket as well as the valve cover gasket (including the valve cover) was replaced at 150,000km. Oil filter housing gasket was done at 157,000km. All work was done at a BMW dealership. I'll add that to my knowledge, the PCV hasn't been upgraded either.
Can't see any oil around the valve cover nor the oil filter housing either
Any thoughts? I was hoping it would be something easy to DIY but if it is indeed the RMS, I would have to get someone else to do it
Cheers
