Question about 1999 Saab 9-5

White smoke from exhaust

I'm also experiencing with my saab, some white smoke coming out of the exhaust almost like white/blueish smoke. When I turn on the AC it comes out like crazy, but when i turn it off it will stop however after some time driving, when I accelerate under 70 km/hr or stop at a stop light it will smoke again, however when I let go of the gas pedal, the smoke will stop. I've changed my oil a few months ago and I've added engine oil. I have no idea what this could be, does anyone have any suggestions?

    I bought my 1999 Saab 95 about four months ago for 3000 and thought it was thebest car I have ever had until today. It started losing power then all the sudden started smoking a white blueish smoke out the exaust. I blieve this is a Turbo poblem but I really am not sure. I am really not very techno savvy when it comes to this kind of stuff. I usually do all my own mechcanic work on my cars but this is all new territory for me.

Could also be a warped cylinder head, especially if you've been driving it that way for a while.
If you are noticing a higher than normal temperature indication, this is also indicative of a blown head gasket, warped cylinder head, or both. If your coolant levels seem to be dropping faster than normal it can mean that you're leaking it into the engine. Or, it can be that you have a coolant leak which caused you to overheat, and then blew the head gasket. It's something of a "chicken or the egg" situation.
The best way to determine if this is the case is to change your oil again and inspect it. If it looks like "milkshake," you have coolant mixing with the oil.

I've had this happen on two occasions, the first when I bought the car and now a second time within the last two months. The mechanic told me it was in relation to a failing turbo. The first turbo failed at around 70k miles, but now im about to have a second fail currently at 140k miles. It costs about $1300-$1500 to replace parts and labor but sometimes you can get a "rebuilt turbo" for les.

Good Luck

White smoke from exhaust = water into the cylinders, when this happens it usually means head gasket gone or starting to go.
Check the water level, and take the car to the garage for a check up , if it is the head gasket, as I think, you risk to blow the engine at any time.

1996 Saturn sl2 smoke problem not head gasket no antifreeze seeping in valve cover gasket leaks and losing about a quart and a half of oil no blue smoke kinda white but heavy a little stops driving

White coming out the tail pipes is coolant/water. Doesn't mean the head gasket is blown, but you'll wish it was. Could be a cracked head. They can crack inside the intake or exhaust port. This would still give you a good compression reading. If in the intake, you would have a misfire. Exhaust you wouldn't. As far as the blue goes. It is mostly white in color, with a hint of blue color. Loosing that much oil would be a major leak or the rings are shot. Rings being shot, you would see that blueish tint in the smoke.

Blueish white smoke comeing from exhaust

Hello There

White smoke when first started is normal. If white smoke continues you have an internal coolant leak, i.e., cracked head/blown head gasket.
Black smoke is caused by a rich fuel condition.
Blue smoke is caused by oil consumption.

You need to check your oil cap for yellow/white gunk on the cap if you have this then this is a sign your head gasket is cracked. Check to see if your radiator coolant level is down this is also another sign.

Hope this helps. Please don't forget to rate me.

Many Thanks

White smoke indicates usually a bad head gasket or worse a cracked head. The gasket is allowing water from the radiator to seep into a combustion chamber and be turned into steam as it exits the exhaust. Check your radiator levels to see if they are dropping and check oil to see if there is a milky substance. If you recently overheated your vehicle, you most likely damaged the head gasket and it will need to be replaced as soon as possible. If this is the problem, the head should be checked for warping by a machinist and re-shaved if it has warped.
Do a compression check to locate the cylinders taking in water.
White exhaust=water in combustion chamber
Blueish exhaust=oil burning
Black exhaust=rich fuel mixture

Firstly, i am experiencing a lot of top ups on oil (1 pint/week). My car smokes a lot and the smoke is white and blueish like. My exhaust is so black and oil greasy residue and some oil is leaking through...

your idle problem is because your carb is missing somelines such as vacuum etc.
the reason your top up is increasing is because your car is burning oil hence the white/blue smoke.
you need your head gaskets changed and also get your mechanic to take a look at your O-rings (piston rings)

White smoke coming from exhaust when accelerating

Is the white smoke steam or water? If so it is a blown head-gasket. Fix ASAP or you will ruin the engine. Or is exhaust blueish/gray or gray and smells like gas or oil. If this is the case then it could be a fuel injector, spark-plug (or no spark to plug), valve seals, piston ring/s, or clogged air filter.

You will need to check head gasket. Please check the oil for coolant (milky deposition or presipitation). Also check if you loosing coolant and if coolant has oil in it.
