Im to assume you have high mileage on this vehicle also. the blue smoke in the morning would be oil that leaks down past the valve guide seals overnight. the only way to permantely cure this is to replace these seals by removing the head. is overheating an issue? if not i would go to the autoparts store and i know they sell an additive that you can add during an oil change. this stuff may help. if not, its a $10 loss and nothing hurt or made worse. if youre looking to invest in your vehicle and spend some money, it would be wise to have the headgaskets replaced and while the head is off, have it machined and the valve guide seals replaced. the headset will come with all the seals the machine shop and you will need to seal the engine properly.

Don't worry about the smoke when your car starts it will mostly happen in cold mornings but as car heats up it should be gone its just cause the car has to heat up to a certain tempeture. Hope it helps.

2006 toyota avalon blowing white smoke in the morning

This sounds like coolant is leaking into the combustion chamber so when it is cool remove the radiator cap and see if the coolant level is low which will indicate that the engine is consuming coolant. Pressure testing the cooling system would be the next test to check for such a lek.

White smoke belching out but will not start

white smoke is usually water, grey=oil dark grey=other fluids. with the belching and other symptoms i would be inclined to believe you have a blown head gasket.

Just bought a 2002 toyota avalon with 100000 miles. it blows blue smoke from tailpipes during a cold start. when it it warmed up and i try to start it, it's fine. the toyota dealership told me they are...

Hi There,, with regards to the blue smoke when starting the engine from cold but none when warmed up, it could be the valve stem guide oil seals. you may need to remove the cylinder head and lap the valves in again but it should last you another 100,000 miles.

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.

White smoke from the exhaust when I start the car


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.
