Newbie Help



I just bought a 2002 BMW 540i. The person I bought it from had bought it last year from a another person. The car was sitting for 5 years by the previous owner. The car has 90,000 km but the problem is the burning of the oil. I removed the plugs and found one plug that was covered in black caked on crud. I replaced the plug with a new one but the blue oil smoke continues to come out the exhaust. Please give me some advise this is my first BMW and is a joy to drive. Thank you

thanks for replying back. I did not notice any oil. All of the other plugs were fine but the one in #7 cylinder was black,full off crud and looked burnt. I was going to do an engine flush to see if it helps. I will also look into the oil well. I just hope its not bottom end work $$$$$$$$$

Let me first say that I'm no expert.
I initially thought vavle cover gaskets but even if they were bad that should not cause oil to burn. After a quick search I found this:

Have you changed the oil?

I changed the oil today and pulled the #7 plug. The plug was only 2 days old and was black and covered in oil. Today I put seafoam in the motor, idles and reved for 15 min. then changed oil and filter. When I started the engine it was smoking constantly then it would dissipate. Once I took it for a ride I noticed blue smoke coming out the back. After 10 minutes of hard driving I could not see any smoke. I am hoping that I have sticky rings that will unstick or dried up valve seals that will reseat. I know additives are not always the answer but at this point I will try anything to fix this problem. Any more input greatly appreciated

I recently read some articles about the M54 6cyl with similar issues - stick rings, high oil consumption. Additives seem to help.

Thank you for the help. I was thinking of putting some acetone into the spark plug hole and let it sit. Do not want to hydrolock. Any methods/suggestions of additives or procedure greatly appreciated. On a side note: This is my first BMW and can actually confess as to how people get addicted to this car. Handling,power,looks best car I have ever driven.....smoking car! Pardon the pun

Italian tune up????

I think acetone would evaporate too quickly to be effective. Lucky for me, I haven't experienced this problem so I'd be of little help. But there are tons of other people on the web that have.... I suggest googling...

Hey Thanks, Today I did a compression test and got an average of 180 psi all cylinders except the one the has oil on the plug. that one read around 160 psi. I just dont know if I should get someone to do the valves and risk the rings being bad or rebuild the whole engine BIG$$$$$$$. I poured some diesel fuel in the bad spark hole and let it sit for an hour. When I stated up the car it was smoking but disappeared after a few minutes of spirited driving. I notice that the smoke is more intense when I park it for a couple of hours or overnight and then start up

I would think the valve seals would fail after only 90k... So how long have you had this car? If it's just a few days, I would recommend driving it some more to see what happens. After all, 5 years is a long time!

I've only had the car for a couple of weeks but have put about 600 highway kilometers and a couple of hundred city. Have driven WOT. The blue smoke and the #7 spark plug saturated in oil is annoying. I love the car though. Want to get over the smoke issue so I can pass emissions. Any emission tricks?
