oil in exhaust
I have had some issues with what appears to be oil or soot shooting out of my exhaust in my 240D and took a video a few weeks ago and finally got around to uploading it. Any idea what could be causing this? This has been going on for at least 4-5 years.

If fuel milage is fairly normal and base oil use is less than 1000 miles to a quart. I would think it could be considered normal. Others with more experience may disagree.
Or to put it another way. If my car met the above paremeters I would just consider it so. Suspecting that the liquid is perhaps condensate in the exhaust being expelled. Last edited by barry12345; 01-16-2013 at 03:00 PM. |

If your injectors are wearing out they can be shooting more of a stream of fuel out of them rather than more mist like.
My VW TD would shoot out a black fart of oil from the exhaust onto the ground as it started. New injectors have decreased it.

I have new to me injectors on the way so we will see what happens with those.

If your issue presists Valve Stem Seals and or worn Guides and Valve stems.
When you remove the Injectors look inside the Prechambers and see if all or a few are Oily looking. Normal they should have a dried flat black colored Carbon

When did you last put in a new air filter?
How much oil does the engine use (carrying on from Barry's post)? When did you last check the IP timing? Ever done a timing chain elongation measurement?

The engine uses about 1 quart every oil change which is every 6 months... usually around 3k miles Never checked the IP or timing chain. I did send off oil from the last oil change to Blackstone Labs so we will see how it looks. I have a bad feeling that the head gasket may be leaking since I have been having temperature control issues lately. Here is another video of the car at idle. I already know I need a new power steering pump. 240D at idle - YouTube And a 0-60 run... not sure what that noise is right at the start of the video but its not the car. I find it funny that after I uploaded this video youtube had it in the comedy category 240D 0-60 - YouTube All that being said the car runs fairly well. As i already mentioned I have new injectors on the way as well as upgraded glow plugs since I'm finally ready to ditch the old loop plugs. The car is a royal pain to get started in the morning even in the garage. I did forget to bring it in a few weeks back and it had to sit outside for a few days until it warmed up. I just preformed a valve adjustment right before these videos were taken and that did not help the cold starting issue. If this car didn't have such a personal history with me and my family I would most likely sell it. |

I vote for condensation. If you actually had oil that far back in the exhaust system, it would be accompanied with great clouds of smoke.

Definitely sooty condensation. Mine does the same thing when it's humid out or lots of snow on the ground, and I don't burn any oil.

Is that acceleration video at full throttle?
I have never driven one.

Pretty close to it. You have not lived until you have tried to merge into traffic on I-95 in a 240D

Cringe....Makes me glad that I have that extra cylinder and 14 pounds of boost. Makes it run almost like 6 liter NA.

Is it just me or is the idle a tad (just a tad mind you!) high?
I wouldn't recommend lowering it if you have cold starting trouble though. Is the swishing sound on the idle video coming from your suspect power steering pump or from the cooling fan or the airconditioning? As for your 0-60 time I reckon that that took you a generous 45 seconds. According to chapter 00-10 you should be capable of doing 27.4 seconds on a two up! I got the impression that it started off quite well but then it kind of couldn't be bothered anymore. The transmission seems to shift well though doesn't it. Oh and the whole the smoke is this the smoke is that thing is something I certainly haven't got to grips with yet - but if it is water moisture then a good long run with a few of those 0-60 starts should get it warm enough to see if there's still the same kind of smoke at idle or not.

It is the power steering pump making the noise in the idle video. My car has the old idle control knob which I always lower down once the car is warmed up. The transmission has been shifting great ever since I figured out the adjustments on it. Mine had the old style control rod and no vacuum to worry about. I think 45 seconds is rather generous on the 0-60 time on this car. Once it is at cruising speed however it runs like a dream. I am not going to have the time or energy to do anything else on the car until the weekend if even then. I am out from work with the flu right now so while I am somewhat free I feel terrible. Hopefully my parts will be here by the weekend though since I am off Monday for the holiday... one of the perks of working for a bank. |

Well get well soon!
But re-e-e-e-wind - 1 US quart = 0.95 litres in new money right? I would be pretty unhappy to be using that much in 3000 miles. (I know there was a chat about oil usage on BW recently and that usage is within specifications in the FSM etc etc but the FSM specs are in my opinion nuts! Back to chapter 00-10 for the OM616 you've got a maximum of 0.15 - 0.25 litres for 100 km!!!!) Does your car mark its territory?
