My son sent me an instant message yesterday saying the 240D was trailing some blue smoke and smelled like it was burning oil.
When I got home last night I started it up and popped the hood. Engine is running a lot louder than it had been. It was night, so it's hard to be definitive but it did seem to be spewing a little more smoke than normal and it did smell of burning oil. The oil level (I checked it before I started after the car sat on the flat for 7 hours) was down a bit from where it was when I brought the level back up a few days back. We checked under the air filter and there wasn't much oil sitting there, so I don't think that's the culprit. I did notice pretty significant blow-by when I pulled the oil fill cap while the engine was running at fast idle. So I have more smoke, some oil smell in the exhaust, lower oil level on the dipstick, more noise - almost like a loud rap, and lots of cam oil pressure. Any thoughts? Could it be as simple as a valve nut that wasn't tightened up enough and now has moved? The sound I'm hearing seems to be coming from a single piston - that is, it's regular but I don't think it happens every time a piston fires. ...Kevin (who'll be checking valve clearances tonight) _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
