2002 5251: oil leak or oil burning?

Greetings fellas,
I have a 2002 525i that has about 180K on it. I have been adding oil at least 1 qt every month. There is some oil spots in the parking lot but I park on a public parking lot and its hard to tell if that oil come from my car or not. But there is a big possibility it did since I usually see oil spots when I pull out in the morning.
Any ideas will help? and what can I do if its an oil leak ?
Thanks

IF your on a stupid poor budget,get some gasket sealer,drain the oil,take the 14 bolts out,dry it clean both sides with a razor,out gasket sealer on install bolts wait 12 hours,put oil back in and drive

3$ and and about 2hours work

OR buy the real gasket. if the pan is leaking,could be a loose drain bolt.

Put a piece of cardboard under the engine to determine the general location of the drips. You can either fix the leaks or not, those are the only options so I don't know why you're asking what to do if you plan on keeping the car

My 530 was leaking and burning, mine a valve cover leak, which was hard to see, except when smoke was coming up out of the cowling when it was turned off. It is normal to burn a minor amount of oil with the inline 6 motors, mine w/ 200kmi at about a quart every 3000 mi (one month for me~)

M54 engines love oil. Failing CCV or other vacuum issues only make the problem worse. How many miles are on that 1qt loss? 1,000/qt is acceptable.
