If you have a head gasket leaking, and your engine is blowing a white smoke from the exhaust pipe, then you're taking coolant/water into your piston/s.

After a heavy acceleration your pressure is forcing more coolant/water into your cylinders..but don't be fooled..water/coolant is also getting into your cylinder/s when you're driving slow too.

You should get the head gasket repaired as soon as you can, or the head gasket may very well let loose and then you get to deal with having the heads shaved if they warp from the heat.

Either way..you really should get the gasket replaced soon.

It is possible that the higher rpm is creating more pressure in the cooling system and forcing the antifreeze into the cylinder, if you know how, do a compression test on the engine and observe the plugs as you pull them for moisture..............however i am thinking that you may have to wait until the problem with the smoke gets worse in order to determine which cylinder is leaking

My 2005 PT cruiser turbo has just started heavy white smoke when idling. Does not happen all the time and appears to run rough when it does


Hi Barbra:
1) I'd be suspicious of a bad head gasket with a possible leak between a cylinder and the water jacket.
If fumes smell like coolant that would be a confirming hint.
Check the oil (dipstick) and see if it has a milky colour or if there is any water visible. If the head gasket problem is only as in 1) above, it should be just oil.
- Temporary fix attempt????? - add aluminum sealant to coolant.
- Permanaent fix (expensive) - Off to the repair shop for a new head gasket.
Hope this helps.

99 Grand Am Smoke Exhaust


I'm sorry to say your engine may be cooked.
Since you are adding both oil and coolant, and the color of the smoke is gray or white, you have the signs of the engine burning coolant.
The common cause is a leaking head gasket.

My car start smoking very heavy white smoke an stop running


You've blown a head gasket. the white smoke is from the coolant getting into the
cylinders thru the faulty head gasket. The fact that it won't run tells you that so much
coolant is getting into the cylinder(s) that the engine can't function properly.
Fix: buy a new head gasket, take the head off the engine, and replace the gasket.

By changing gears I've got smoke coming from my exchaust: what can I do to prevent it. What Oil is best for my TDI. Can I use fuel injector oil with the diesel.


Identifing the smoke color tells you where it is coming from. Black smoke comes from fuel, so it is running rich or not fully igniting the mixture. White smoke comes from oil and often happens under very heavy engine load. On acceleration this could be the piston rings allowing blow-by, on deceleration this could be the valve seals leaking. Blueish smoke is often coolant, indicating a head gasket leak.

You didn't state iof this happens during a moving gear change, or if it has happened since you physically changed some of the gears in the car. On a TDi, I would follow the factory recommendations for all engine lubricants and additives.

Blowing white smoke when reved up.... boggs a little when accelerating, idles a little rough also.. its a 93 civic dx with a 1.5l


White smoke is usually caused by a cracked head gasket or cracked head, but some times it is caused by your brake booster sucking brake fluid into the intake through the vacuum hose. If your brakes are constantly going soft, or your brake reservoir constantly needs refilling then that will be your problem. Replacement will include both the brake booster and the master cylinder.

If the cause is a leaking head, you can fix it with sodium silicate (liquid Glass) which can be purchased in most pharmacies. You will need to remove your thermostat to keep it from sticking shut before doing this. Replace it after the smoke is gone.

Remember that the sodium silicate trick is more of a bandaid than a permanent fix. Also remember that sodium silicate is not a good fix for steel heads, and since yours is aluminum it should work.

BUT since your problem only occurs as you accelerate, I would suspect the brake booster and master cylinder.

My car started smelling funny...pulled over lifted hood and it was steaming...white smoke came from under hood and tail pipe, car would not start again. Some say it may be a head gasket? How would I know?


You can tell by looking at dip stick if the oil has a creamy white substance there is antifreeze getting in oil (blown head gasket) or if ther is excessive white smoke coming from exhaust pipe upon acceleration. steam from under hood may be a coolant leak from a rubber hose or it may be leaking from the cylinder head onto the exhaust manifold also the car will be using up antifreeze.

White smoke coming from exhaust when accelerating


This is usually an indication of a bad head gasket.I gasket. The white smoke is the coolant leaking out of the engine and winding up in the oil passages, due to a bad head gasket. To confirm this,
1. check oil. Is level increased, or milky appearance?
2. Is coolant level dropping, but u don't see any signs of leaks?
The above indicates a bad head gasket, causing the white smoke u describe. Let me know how u make out.

Saab 9-5 blowing white smoke from exhaust


One way to check for a blown head gasket, is to simply smell the coolant reservoir. Pop the cap, and see if it smells like raw gas. Every headgasket, I've diagnosed has had this smell, even if the oil is not contaminated. Another way is to hook up a coolant pressure tester, and run the vehicle for 15-20 mins or so. If the head gasket is blown, the pressure will exceed 15 psi. sometimes as high as 25 psi. If there is oil in the coolant overflow tank, the head is cracked, about 90% of the time.
I'm working on a 03 Saab 95 2.3l t. This vehicle smokes on initial start up, then the smoke disapates, and the vehicle is fine. Another mechanic diagnosed it as bad valve seals. I disconnected the pcv system, and the vehicle no longer smokes. If the valve seals have gone bad, the vehicle will smoke on acceleration. Also if the turbo seals are leaking it will smoke more heavily on acceleration.

White smoke from exhaust


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.
