White smoke its blowing white smoke when cold smells like over heating but is showing normal ongage

White smoke is oil burning off. Try manually cleaning the filter with compressed air or at least tap it on the floor or bench to knock down the amount of dirt in it. Back to your question, not likely. Try to smell the smoke, if it smells like oil or if it smells like antifreeze.

If the temp gauge is at normal, then what makes you think it is overheating? Are you experiencing water being forced out of the cooling under pressure? That is what makes some think the car is overheating. White smoke from the pipe can be normal, but only for a short time after start-up. If you smell the exhaust and can smell an anti-freeze odor in it, then you probably have a blown head gasket, cracked head, or cracked block. This can cause over-pressurization of the cooling system and coolant overflow. Usually, overheating accompanies this issue and is normally the original cause of it as well.

smoke is white or black.?
black is flooding and misfire.
White 1, is oil, smell like burnt oil, and take bloody for ever to clear.
White 2, is steam and is normal, but not so if smells like Antifreeze sick sweet smell and dissipates fast like moms tea pot steam.

how to you like MY smoke answers. good?

1: check all fuses in both boxes.
2: Scan the PCM. with any OBD2 scan tools , they rent for free. ask.
see DTC errors?, post em.

White SWEET smelling smoke, or white OILY smelling smoke? If it's white thick SWEET smelling smoke, you have a blown head gasket - that's the smell of antifreeze burning in the engine, which it should NEVER do. If it's white OILY smelling smoke (smells a lot like diesel), then you're getting too much fuel into the cylinders.

If it's sweet-smelling smoke (antifreeze), pull the oil dipstick & check the oil level. If the oil level is HIGH and the oil looks like a mocha milkshake, that's absolutely conclusive - that's what happens when antifreeze gets into your oil, and it's nasty corrosive to engine parts.

I'm not at all surprised that the oil light is on if it won't start - you won't get much oil pressure until the engine is running.

mine does the same thing.. it is a sign that you are burning oil kiddo..either that or antifreeze is finding its way into the engine through a crack or bad gasket.. check for oil smell and moist soot at the tailpipe, or a sweet smell if antifreeze..now if its a steam like smoke..thats normal byproduct of the burning fuel and goes away once the exhaust pipes and muffler heat up enough to blow out all the condensate water...

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...

Valve seal leaks will cause an engine to smoke on start until the oil burns off. If a head gasket were leaking it would be smoking constantly.

White smoke (sweet smelling, too) means antifreeze is leaking into the combustion chamber, blowing out the tail end of your truck. the boiling water in your reservoir means the pressure from the combustion chamber is pushing air into your cooling system which will eventually surface in your reservoircontainer

black smoke: it can be unburned fuel damaged turbo charger etc. light amount of smoke can be normal large amounts = problem.

White smoke means your buring oil

White smoke usually occurs when there is not enough heat to burn the fuel. The unburned fuel particles go out the tailpipe and typically produce a rich fuel smell. It's not unusual to see white smoke in the exhaust during cold weather until the engine warms up.

Faulty glow plugs or control module can cause white smoke on engine start up.

Low engine cranking speed may also produce white smoke.

If white smoke is still visible after the engine has warmed up, the engine may have one or more bad injectors, retarded injection timing or a worn injection pump.

Low compression or air in the fuel system can also be a source of white smoke.
