After driving the car for short distance, oil starts smelling strongly. I haven't noticed any obvious leaks in the garage, just the smell of oil more from the passenger side than the driver side.

burning smell from engine compartment. starting to show visible leakage from rt side of engine onto exhaust, hence the burning. Was quoted $250.00 for "valve cover gasket service" from local BMW house. Doing it myself for $30.00.

not yet fixed...........cheaper to add oil every 3000 miles
2004 BMW 330i 116,000 mi,
Oil burning smell and smoke coming from engine compartment near windshield by driver side. The valve cover gasket was found to be the problem; it was leaking on the hot manifold. Had the valve cover casket replaced ($265). Problem fixed.

Oil smell inside car, was result of oil gasket leak due to two broken bolts. Mechanic indicated that this is a common problem and there is a service bulletin that adjusts the torque specs when installing new bolts. Cost was $800.

I have a 2006 BMW 330i with valve cover leak that is flooding the 3rd spark plug tube. I discovered it when I changed the spark plugs and ignition coils for the 100,000 mile tune up. It has not been fixed yet.

Oil drips and creates smell of burning oil.Looks like Casket needs replacement. Also I think my struts are in need of replacment.

Noticed strong oil burning smell, and found leak during spark plug replacement. Quoted $575 from local foreign shop. Service manual evidently says 5 hours, which seems steep since I was just a couple steps away from removing the cover when I did the spark plugs.
