You DO NOT need an oilseal.when you burn gas the car produces almost a gallon of WATER.this sometimes collects in the exhaust box at the back of the car and when you start it up you see CONDENSATION,not smoke,if were oil it would be BLACK.tell the person to hold a white hanky to the tailpipe ......and kiss my a.......sorry, but this kind of "mechanic"makes me see red....

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

When I go to crank my car up white smoke comes out but the only time it do it. How do I fix this?


Sounds like white smoke is antifreeze. It might be leaking all of the time. Does your antifreeze level fall gradually over a week's time?

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.

While starting car little smock come for few mnt why ?


If you get a little puff of white/blue smoke just at start up , it probably means that one or more of your valve guide seals are worn.
While engine not running , a bit of oil gets in the cylinder , when it starts the oil burns off causing smoke. If it was smoking all the time , I would say rings are worn. If it is black smoke at start up , it indicates a fuel mixture problem. The valve guide seal problem may get worse over time.
On your post you say " for few mnt " if that means a few moments , than Valve guide seals , if you mean a few minutes , than more serious piston ring problem. Change your oil , and add a can of RESTORE , it will fill small scratches in cylinder walls , but will not fix badly worn rings.

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.

89 chevy s10 blazer puff smoke out tailpipe when 1st started


A puff of smoke when you start up indicates worn valve seals.That's why all your work didn't fix the problem and it doesn't show a code. It's a pain in the --- job that requires some specialized tools so I guess it depends on how bad it bugs you,if oyu want to fix it.

My 300zx got smoke issue but im not sure.smoke come both sides when i start the car.it got little oil leak from turbos.but once engine got hot the smoke goes away.when driving it doesnt smoke.but it...


It sounds like you may need valve seals.
The oil sits in the head after the engine is cut off and leaks around the seals into the cylinder.
When you start the engine it burns the oil and sends the smoke out of the tailpipes.
It does not hurt anything much if it is not to bad.

Big puff of white smoke at start up after sitting for several hours.


white smoke is water
blue smoke is oil.
nest time try and smell the white smoke see if it smells sweet?
if it does its antifreeze.
and also black smoke is fuel (like a leaky injector )
hope this helps
