Very smokey (smelly) exhaust

Hi - I recently bought a 51,000 mile (yes) 2-litre petrol 940. It's blowing out a lot of grey-ish smoke on pretty much every drive, even at idle. A garage told me that it could a worn turbo or it just needs a long drive to clear out the system if it's been sitting around unused (which it must have been). Any ideas? Thanks very much

Grey-ish smoke sounds like rich mixture,not oil burning.Grey-to black is usually excess fuel.Whitish smoke is coolant being burned-bad news! If rich mixture,check for air intake leaks (air intake hoses/manifiold gasket),MAF,fuel pressure regulator.

It sounds like either you have leaky piston rings or partially blown seals in the turbo. the seals kit shouldn't be very much but depending on where the turbo is, it could cost a lot in labor. piston rings are a whole different story.

3.0 litre V6 turbo diesel Mercedes. 115,000 miles. When it is left on tickover for 10 to 15 mins starts to smoke white/grey smoke from exhausts. After a few minutes of normal driving the smoke stops.


Possible cause is several drops of oil are leaking past the valve guide seals when the vehicle just sits. When it is started the oil begins to burn off in the cylinders and after awhile the smoke disappears. I have always recommended cha going the oil to a synthetic and adding an oil additive called Restore. It comes in a cylindrical can in 4, 6 or 8 cylinder size. Put 1 can in with the new oil. Drive the vehicle on the highway for 45 - 60 minutes. I recommend putting on a few hundred Mrs. The additive restores the valve seals preventing the oil from dripping into the cylinders. Have used it on my customers vehicles for 20 years. Saved them a lot of money from replacing the seals.

My mazda 626 has a strong potent smell coming from the exhaust


You don't mention what that smell is reminiscent of?

You don't mention the colour of the "smoke" and you didn't say whether the engine is petrol or diesel?

You don't mention whether the road behaviour/performance is normal?

White smoke is almost always steam or in the case of a diesel it could be an unburned fuel mist, grey/black is excess fuel and blue or grey/blue is burning oil.

Some steam is fairly normal until the engine and exhaust system is hot but excessive amounts could be one symptom of head gasket trouble. If the engine is drinking coolant and sending it through the exhaust as steam it will sometimes smell spicy.

Burning oil smells a bit like burned eggs in the frying pan.

If the car hasn't ultra-low sulphur oil and fuel the catalytic converter will convert sulphur traces into hydrogen sulphide - the bad egg gas...

All the oil gone after a 20 mile round trip - has it burnt off or did it leak - that's the question - it's a 1.4 y reg golf - petrol...


I can't imagine that your car is "burning" all that oil in 20 miles. To be sure, remove the spark plugs and look for a lot of ash or really black/oily plugs. I would say more than likely you have an oil leak. Check under your car for a lot of oil streaking. At that rate it should be everywhere underneath.

Black smoke points to unburnt fuel. I would start by replacing the spark plugs and wires if you have not done so in the last couple of years.

Blue smoke out of exhaust, replaced turbo, still smokes a lot when engine revs


have you driven it at least 100 miles since repair?, the oil residue builds up inside the exhaust and burns off very slowly from the previous failed turbo seal.
