DING! How recently? How hard have you been driving it? You did have a bad thermostat at some point not all that long ago didn't you? I seem to remember that.
I'd guess your carboned up rings are starting to let go of the carbon resulting in them seating badly as the carbon comes off unevenly. In which case the solution is to drive it like you stole it and keep shorter oil change intervals until it clears up. -Curt Date: Wed, 3 Jun 2009 02:40:16 -0700 From: Zoltan Finks <mmmmmsuchpo...@gmail.com> Subject: Re: [MBZ] our 190D starts to burn oil To: Mercedes Discussion List <mercedes@okiebenz.com> Message-ID: <65200d420906030240i1714e42mc3ca08d40dc7d...@mail.gmail.com> Content-Type: text/plain; charset="iso-8859-1" It's the 2.5 non-turbo. I recently switched to Mobil 1 15/50. Haven't checked the crankcase breather. Could that being clogged cause this? For some time, it has made a ticking at idle and at cruising. Lately, I have suspected it has been more noticeable at cruising. Odometer stopped at 279k mi. I reckon it's up around 300k now.
