Question about 1994 Volvo 940

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.

1995 izuze rodeo its losing power and is blowing smoke out my exhaust what's problem help


is it smoke or is it steam , if upon having noticing that it is steam a possibal head gasket issue or corrosion of the head. if it is smoke check oil not over full . if smokey all the time and oil smoke (blue or white ish colour more inspection of compression test and other diagnosis needed but could be worn oil rings and some times still may have equal compression on all pots the oil ring is there to prevent oil getting into the combustion chamber while at the same time allowing lubrication of bore , when they weaken the oil that gets past burns in chamber and that's the smoke . there are other components like valve stem seals that can allow oil to escape into the combustion chamber buy from your descrition that's a good place to start

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.

Daewoo Nubeira ...black smoke from exhaust + keeps overheating, do you think it is head gasket or could it be something else??


i pretty sure thats a head gasket. black smoke comes from burining oil. white smoke comes from burning antifreeze.
