I just got all those fixed..
Valve Cover Gasket:
Got this fixed couple weeks ago..Shouldn't be more than $450 the smoke is from that because the oil is dripping onto your headers. Get that fixed asap.
Oil Filter Housing Gasket:
Just fixed it last night. Its a $15 part and shouldn't be more than $200 including the part to fix.
I also have a leaky oil pan but I'm going to wait that out for a while longer til I hit 100k miles in about 10k more.
These 3 are the main problems with our cars everyone runs into them sooner or later so its very common. Just get them fixed make sure you don't get ripped off and they use Genuine BMW parts.
