I NEED HELP FROM SOME E39 MOTORHEADS! I have 2003 530i with 76k miles, I bought the car knowing about an infrequent (a couple of drops a week) oil leak, supposedly where the canister oil filter mounts to the engine. I have noticed the leak becoming more frequent. Other notes, there was a weird plastic cracking sound when started (from cold) a couple of months back, and it infrequently has a sound when starting it. I also almost ran the car out of gas and when I filled it up the SERVICE ENGINE SOON light came on and the car ran horribly for about 20 minutes, when the car sat for awhile it started and ran just fine and the SES light went off. Then a couple of weeks later I sometimes noticed white smoke from exhaust immediately when started (and maybe the smell of burned oil). Other times no smoke was noticed (whether warm or cold). I pulled the spark plugs and they all appear moderately oil fouled. The car appears to idle fine and it has the proper amount of oil in it. I hope it is not the head gaskets, but rather the valve cover gasket(s)???? But what would cause moderate oil fouling ...and lots of white smoke when started...and smoking now when it is running...man I really don't need an expensive repair in this economy!
