Question about 1999 Saab 9-5

1 Answer

Burning oil i have a saab 95 econ thats eleven years old. when i pull away from the drive in the mornings it puff's out white/blue smoke till i put my foot down and blow it out, after thet it's not a problem. some day's it's worse then other's mainly if it's got oil in it. if i go over half way on the dip stick marker then it poors out more smoke then normal. i know the colour of the smoke means it's burning oil and the more smoke the more oil it has burned, thats y i have to leave it so low. the car is not using water and it not the head gasket. i just wounder would anyone know what the problem is with it and would it be worth fixing on such an old car

I believe what you have going on with the car is your Valve seals have gotten brittle and have cracked. now the reason it smokes on startup is because when you shut it off. the oil is bypassing the valve seals and is collectiing in your combustion area. this is very normal with older cars. or cars with high milage. and as far as the price factor goes it is hard for me to tell you if it is worth fixing or not. because you will be looking at taking the heads off and puting in new head gaskets. but i have a 1976 dodge pickup and i replaced my seals because that was the only problem with it. now all i can tell you is take the car into a shop and get a compression test done to the motor this will give you an idea if the motor is worth it or not. if the compression is up to par i would replace the seals if this was my car.

I have a Z24 Cavalier and theres white smoke coming out the exhaust and timing chain makes a lil rattle noise when I first start it in the morning and tends to stall until it reaches the temp of 165ish...


So if it's not consuming oil and you are SURE to fill the radiator to PROVE it's not burning coolant ... then the other suspects are head gasket and .... A puff of smoke upon start-up could be caused by valve guide seals allowing some oil to leak down into the cylinders while the car is parked and not running. This would be pretty common on a nine year old car and should not, in most cases, be cause for concern - See more at: http://community.cartalk.com/discussion/2280708/white-smoke-from-exhaust-upon-cold-start#sthash.05fuptIx.dpuf

If it's blue-white then What you might be seeing is oil burn-off from leaking valve guide seals. The next time you have the oil/filter changed, have a high mileage oil installed. - See more at: http://community.cartalk.com/discussion/2294478/white-smoke-coming-from-the-tail-pipe#sthash.jVo0zDhw.dpuf

Some smoke is normal in high milage vehicles. As long as there isn't smoke coming from the pipe all the time you will be ok. Mostly what happens is the valve seals will deteriorate and leak some oil into the piston chamber which will burn when the vehicle is started.

My 2004 audi A4 consumes oil at a rate of 1 1/2 quarts every 3 months. There are no apparent leaks and it is not burning it. It idles and runs smooth. Any suggestions?


How many miles/km's you drive in those 3 month's ? oil consumption is normal ! Check when you first start the engine in the morning wetter or not you see a puff of blue smoke, if you see smoke , your valve seals are leaking.
1 liter oil each 2000km is normal.

Morning White Smoke At Start-up (2003 4cyl Camry)


This problem is common but often over looked. Moisture vapor is a grayish white color but it dissipates very quickly. Smoke that is grayish white is caused specifically from burning oil. The problem you have is a small seal called a valve seal. It is very common in cars that sit a fair amount of the time. The seal gradually starts to leak and allow tiny drops of oil to drip into the combustion chamber. When the engine is started then it smokes until the oil is burned. Due to the amount of time that your car smokes after start tells me that the leak is very small. That is why there is no oil consumption. This is not going to harm the car unless it becomes very bad and then the only thing that would happen is more smoke and fouled plugs. You can start using a heavier weight oil and add an oil treatment to the oil when you have it changed. This may evin stop it all together. Hope this answered your question. Please rate this solution if you think it has helped. Good luck and thanks cj2176.

My car smoke in the morning when I spark it. When I drive for a few miles it stops


possibly just condensation (steam) white-clear worse in colder enviroments
possible valve stem seals worn or gone hard
if its manual it may give small puff of (blue-grey) smoke out of exhaust in between gear changes at higher revs or on deceleration from hard rev while stationary it will also smell like burning oil

CLOUD OF SMOKE ON COLD START WHAT COUD BE THE PROBLEM AND IS THERE AN INEXPENSIVE SOLUTION


Your issue would be bad "valve stem seals". They are hard rubber seals that wrap around the valve to seal out oil, and prevent it from going into you cylinders. When they get old and worn out, they will allow oil to seep into the cylinders.

When I start my 1998 plymouth grand voyager I get 1 big puff of white smoke. What could the problem be?


It sounds like oil is seeping into the cylinders while the car is stationary and then being burnt off in one big puff of smoke when you start the engine. You're probably also burning oil when the car is running. You may notice that you have to constantly add oil to keep the level up. It's not uncommon for old engines to burn oil. The proper fix would involve either a ring job or a valve job both of which involve quite a bit of labor. If you had to pay a mechanic to fix it, it may cost more than the car is worth. It not a great solution from the air pollution standpoint but you could probably continue driving the car for years by just adding oil as needed. You may have to replace the spark plugs more often because the burning oil will tend to foul them.

Puffs blue smoke


Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles.

This could mean a cracked head or bad gasket....It costly
