Does it happen usually after idling for a bit? What oil weight are you running? You said you're going for an oil change today... does the dealership do your changes? Are they putting in 5w20?

Sounds to me like its a turbo issue. Pull your intake and check for shaftplay. Then pull an intercooler pipe and see if there is any oil coated in the piping. Just an idea though.

For further investigation, to see if its a turbo issue or motor issue. Pull your exhaust manifold and see if there is any oil coating in the exhaust ports in the head or in the manifold. If not then check the O2 housing after the turbo.

Good luck.

Ford Festiva '93 Smoky on startup


Well it has fuel injection instead of a carb, so there is no choke.
You are right in thinking the black smoke is fuel and the blue smoke is oil.
It could be a leaking fuel injector, or a problem with the engine temp sensor. The temp sensor could be telling the computer the engine is much colder than it really is.
It may have an air temp sensor too.
I don't know if you can hook up a scanner to see what the sensors are reading since the car was made in Korea by Kia Motors.

Have excessive blue or white smoke from exhaust when truck is started after sitting for a few hours 2005 f250 6.0 ehgine


Hi,
is it a diesel or gas engine?
Usually excessive blue smoke on start up indicates oil is getting into the combustion chamber. It could be piston rings or valve seals.
Quick check, drive it within operating range and speed. Either use the rear view mirror or get someone to drive it and you follow in another vehicle. Accelerate, then take your foot of the accelerator. Blue smoke under acceleration indicates piston rings / pistons. Blue smoke on deceleration or the "over-run" indicates worn valve guides / seals.

White smoke can indicate coolant in the combustion chambers / leaking cyl head gskt, or incorrect fueling. If brake fluid gets into the combustion chamber it will generate a lot of white smoke from the exhaust. However, that would entail a leaking brake master cyl and a leaking brake booster.

Good luck.

Lots of exhaust coming from my car?


You mean lots of smoke? White, blue, black? Or just smelly stuff? Rotten eggs or shotgun shells, usually an oxygen sensor. I will give you the rundown, white smoke when first starts up is gas, should clear up in a minute.No big deal, normal. Black smoke, carbon, burning rich, settings are way off, computer is not right, oxygen sensors or air flow sensors are bad. Blue smoke is oil, you have lost comp and oil is getting into the cyclinders. Steam, comes out after it warms up and is a blown head gasket. You can look for oil in the radiator. A radiator shop can tell you if it is blown or not. Hope this helps.

Blue smoke


sorry to say blue smoke is oil and with what you've described sounds like the oil rings on the pistons have given up the ghost, time for a new engine or a rebuild sorry for the bad news. valve stem seals are the only other thing that will cause exhaust smoke but only when you first start the car never while running. hope i have been of some assistance.
