Usually this is an indication of water in the oil, pull your oil level dipstick and see if you see water bubbles on the stick.
If so it is probably a blown head gasket.

SOURCE: diagram for 1998 buick lasabre serpentine belt

I found the diagram in my owner's manual.
I replaced the belt on mine just 2 days ago. All you need to do is remove one bolt from the lower motor mount and remove the spacer. After you relieve the belt tensioner, the belt will slip right through the gap. Don't forget to support the engine before removing the bolt. As a backup I took a photo of the belt with my digital camera beforehand... just in case.

Smoke from inside the engine


A little bit of smoke (or vapor) is normal. When the oil lubricates the cylinders some of the smoke from the detonation mixes with the oil, when you open the cap it's released. You could also be seeing a bit of water vapor coming out. If you see A LOT of smoke then you probably have worn cylinders (check with a pressure test) or a bad head gasket, or a cracked block. The latter two will cause your coolant level to be low and your engine to over heat. Let us know if you have any of those symptoms.

check your oil dip stick and under the oil cap to see if there is a milky brown foam. If so there is water in the oil. This can cause white smoke.

Could be oil dripping from the valve cover onto the exhaust pipe.
One drip can cause alot of smoke when it hits the pipe.
Could be power steering fluid too.

the one thing in your statment is the knockes/knocking this what is known as the big ends and indicates the engine is under pressure and needs a lot of repair.If when you start the engine when cold if you stand at the back of the car and if the smoke coming out of the exhaust has a blue tint/ie like a old ladys hair tint ,as im sure you will see.[bottom line] the engine needs replaced.adrian,,,,

Would a defective fuel pump cause white smoke from exhaust?


probably not. White smoke in the exhaust is a sign of either coolant or oil entering the cumbustion chambers (cylinders). Faulty fuel pumps usualy stop delivering fuel to the engine and it won't run at all.

Engine smokes when cold.but runs great,all gauges show engine is running normal, engine only has 39,000miles on it


White smoke is the result of burning coolant and the blue is a sign of burning oil. A common cause of this is a blown head gasket.

This could also be caused by bad valve guide/valve seal that allows oil to seep into the cylinder while the vehicle is off. When started the smoke will come from the xhaust as that oil is burned. Within a minute or so the smoke stops because no oil is seeping intot he cylinder.

Check the plugs for signs of coolant, oil, or burning.

I have a 1999 Mitsubshi Galant that blowes white/purple smoke after it has idled. Lets say at a stop light, or for the morning crank up. I am also having to add oil in between oil changes. Is there any...


If you're sure it's "smoke", then it's probably burning oil. But most likley it's water vapor. When an engine is first started and the air is cold, the water vapor in the exhaust will create visible steam. Automotible exhaust primarily consists of carbon dioxide and water vapor. If the engine and exhaust system are cold, the exhaust will be cooler when it comes out and it can create a cloud of water vapor.
However, if it's not water vapor, as I mentioned above, it could be oil smoke. If that's the case you need an engine rebuild since you probably have bad rings.

Changed spark plugs in 97 buick lasabre and now it cranks and runs, but white smoke coming out. Is that blown head gaskets? Does it have anything to do with the fuel pump my mechanic put on 3 weeks ago???


You need to check the oil with the dipstick (wipe in down a few times) to see if it looks like a chockalate milk shake. If coolent has made its way into the oil you have blown head gasket. The fuel pump which is usually in the gas tank in most gm vehicles would not cause white smoke, if it failed you car would not start because your engine would not get any gas to the injectors
