Question about 2003 Toyota Camry

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

Ok folks, I have found 2 posts listing this same problem on FixYa and have found other references to this problem elsewhere on the net. The smoke is whitish, it occurs only after sitting several hours overnight winter and summer, it lasts 3-10 seconds only, the dip stick shows no oil use. It began a year ago and hasn't changed. I've heard/read every solution for the problem but it is always "maybe this and maybe that", water, oil, seals, condensation, whatever. I don't believe my Toyota dealer service mgr who says it is caused by "leftover unused fuel vapor and condensation" and "that there is nothing wrong with it"! I asked him, if that's true, why didn't it do it when it was new!! (It began just before my 50k warranty was out.) I wrote the Toyota regional service manager, Jimmy Seabaugh, and did not get a reply. Something Specific Is Causing This and Someone Somewhere Has Got It Figured Out! Where do I go to find that person?

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.

Many people are misguided with the smoke coming from exaust pipe in morning. Sometimes my camry sends a puff of white colored smoke at the time of start up in morning. Based on suggestions available on internet I thought of seeing mechanic about this problem. Most of the suggestions on internet were related to mixing of coolant with oil causing white smoke. My mechanic then inspected my car and then asked me question 'do you see white smoke during whole day or just at the time of start up in morning?'. I answered only in morning. He said it is quite common for a car producing white smoke in morning because of internal combustion of remaining fuel in engine. And I should not worry about it. If there is a problem of oil and coolant mixing then car will continuously produce white smoke. And that gave me a sensible answer and relief. I suggest those whoever get panic of white smoke should keep cheching their cars based on below points for a week- 1. Check coolant level every morning if it is reducing drastically day by day 2. Check oil if it has turned chocolate brown. Obseve it every morning 3. Check if car sends white smoke continuously If you see any of the above condition being satisfied then immediatly see a good mechanic. Dont get panic

If your drive your car less than 20 minutes before parking it overnight, there will be water condensation in the exhaust that will produce white smoke in the morning. There should be a small hole in the shell of the muffler to allow this to drain out. Perhaps it's plugged. If there is no hole, drill one but only through 1 layer of metal. Hope you know the difference between the converter and the muffler.

If you drive longer than 20 minutes, the condensation should be evaporated and there must be a coolant leak into the exhaust. That means a problem with the head gasket needing a pressure test of the coolant system.

Blue smoke is a whole other story involving oil.

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.

I found this on the internet. I've used the product for years re performance and fuel reduction purposes. It may help others.
From Toyota forum post:
"I have an 07 Camry Le with the 2.4 L oil burner. I added this oil treatment called Eco-Tek and it stopped burning oil! My gas mileage also improved from an average of approx 9.0L per 100k to 8.3L per 100k with a mix of city and highway also noticed a pick up in power that even my wife noticed clip_image001.png. The website is listed below with more info."

It sounds like your valve seals are getting old and are leaking oil into your pistons.As long as it is not using a lot of oil or fouling your spark plugs drive the heck out of it and look the other way when you first crank it up in the morning.
One other problem that will cause this is a cracked head or a leaking head gasket which is getting water on your pistons overnight. Watch for #1 low antifreeze in your radiator #2 higher than normal engine temperatures. This could be a serious problem that could cause expensive damage to your engine if not corrected.
