Common problem for the age of Bmw. It's the OSV. Oil separator valve. Unless you have 300k miles it's not the Piston rings.

I HATE TO TELL YOU THIS, BUT A WHITISH LIGHT BLUE SMOKE IS NOT YOUR VALVE SEALS....IT IS YOUR PISTON RINGS. IF YOU REV YOUR ENGINE, AND MAKES MORE SMOKE, IT IS DEFINITELY YOUR RINGS.

SOURCE: white smoke from the exhaust when I start the car

Hi!

What type of smoke can you see---

white smoke-
If you see a wispy, lingering white smoke that has a bittersweet smell, this is an indication that your car's engine coolant is leaking into the combustion chambers. This may be due to a leaky head gasket, or in a worst case scenario, a cracked cylinder head.

Make sure to take your car to the shop right away to get it fixed.
Thick white smoke---
If your vehicle is belching white smoke upon start-up, it is a sign that transmission fluid is entering the combustion chambers, possibly though a vacuum tube that connects the engine to the transmission.
This type of smoke can be confused with the normal puff of steam during start-up. If you are not sure, have your car inspected at the shop.

Blue/White Smoke--
A blue/white smoke is an indication that oil is being sucked into the combustion chambers through the valve guides. A quick fix for this problem is by replacing the valve seals. Valve seals are small, umbrella shaped pieces of rubber.

Do rate the solution.

Thanks
Rylee.

SOURCE: 2002 525I Just after recent

I had a similar problem with my 2003 325iT w/59K miles last week, right after an oil change. It did it more often when starting the car, and once or twice when accelerating. Then it stopped smoking and hasn't in several days. My mechanic neighbor suggested that it may have been too much oil, that has corrected itself by burning off. I hope he's right. I figure the smoke stopping is either a good thing or a really bad thing. No engine warning lights or anything, so I guess all is well.

You are smelling burning antifreeze. likely a head gasket but only testing will determine that for sure...Do not drive it. get it to a shop or more damage is likely.

SOURCE: can the vacuum pump cause white smoke

white smoke is caused by coolant leaking into the cylinders. This comes from either a cracked head, or blown head gasket. You're probably also experiencing a slow, steady loss in coolant as well, and in some cases, you may find oil in the coolant, though BMWs don't always do so. It will often happen after it's overheated for some reason, but is not always the case. You need to get your car checked out right away, as this can damage your engine significantly in a short amount of time.

I have a 2005 jeep liberty that has white smoke coming from the exhaust when idling and it smells like burnt firecrackers after driving it when I turn the engine off. Any ideas?


If it is the v8, the most common cause for greyish, white smoke is bad valve stem seals. True white smoke smells very sweet and is caused from coolant being buring in the combustion chamber.

Thick white smoke on start-up. After engine warms up very little smoke or no smoke at all noticable. could it be the PCV valve?


white smoke indicates a coolant burning problem. most likely a head gasket and when it gets warmed up the expansion of the mating components seals off most of the leak. have a head gasket check done. burning of oil is a bluish colour not white.

White smoke coming from tale pipe


Be sure that smoke isn't steam . It makes a difference. If it smokes all the time the piston rings are worn out. If it smokes only after idling then stops soon after accelerating then the valve stem seals are worn out. If it turns out that that white smoke is really steam then the engine is burning water. A bad head gasket is usually the culprit.

I havea daewoo nubira and we replaced the valve cover gasket yesterday , did an oik change and now the engine is smoking white smoke. Try to check to hoses, could not see a leak. Where is the cylinder...


Hello and welcome to FixYa!

The cylinder head is located on the center of the engine. Yes it can be a worn out head gasket or piston rings. If the piston rings are worn out the oil is burnt that's why it emits white smoke. You will need to replace the head gasket and piston rings.

Hope this helps and thank you for using FixYa! Have a good one!

Hi I have Ford Focus 2.0 trend 2000 modle and it smokes heaverly on start up but once it is warm no smoke at all. I have recond the head complete and sent it back for a check, they there is nothing wrong...


I would need to know what color this smoke is because of it is white then I would say that you are probably witnessing normal operation. Modern Cat. Converters are designed to reduce emissions to carbon dioxide and water. This water condenses in the exhaust as it cools while shut off and produces white smoke when restarted until the exhaust is warm enough to evaporate the moisture. If the smoke is blue then you are getting oil leaking into the cylinder and it is probably coming from the valve seals but without a visual inspection that is impossible to be sure.

My x5 4.8 smokes some when in idle


White smoke- head gasget, dark or bluish smoke-piston rings or valve seals. A good indicator of it being valve seals is: after being parked a while and restarted the smoke will be more intense for a short time.
