6G Celicas Forums

On boost my celica is smoking, its a white / grey smoke, and after a hard boost my car has a nice sweet smell ? I'm guessing my turbo seals have gone, but wouldn't the smoke be blue ?
My car is consuming abit of oil too which pushes me to believe the turbo seals have gone.
Any opinions ?

The smoke most likely has a blue tint you dont notice, def turbo seals.

A slight sweet smell is usually coolant. Also light colour smoke is often coolant too.

Oil smoke colour varies slightly depending on where its burning, I.E. if its a turbo seal will be a bit more blue then if it gets burned in the engine.

Mine smokes too on boost (according to a friend)
and thats with a brand new disco potato GT28RS.

you'll have blown turbo seals when this happens http://www.youtube.com/watch?v=61f2oO_rrfc

till then its probably nothing, you can get a compression check if you like, i had 180,170,170,180. and you'll know when you got a blown head gasket as everything will be a mess, mixed coolant and oil, no power, oil light on, etc

If you're worried, get that check that tests the radiator coolant for exhaust carbon

When your vehicle smokes White cloudy exhaust, it's usually from Coolant. If you say it's a sweet smell, you bet your ass it's coolant. Rats fall for that smell all the time, always fine dead rats on my coolant drain bucket at the shop. I'm assuming you slapped on your turbo without rebuilding your engine huh? When you add turbo it increases the compression, when your gaskets are already worn from normal driving then challenged with boost, it could be that you have a leak in your head gasket, more comenly dents or grooves in your head. That requires machining. But the deadliest on is a crack in your block or head that is leaking coolant into the combustion chamber.

If you want to test out if you really have a coolant leak, get a radiator funnel add coolant till half way. Let the car run until it reaches operation temperature. when it reaches that temperature the thermostat will release the coolant allowing it to circulate. If you see bubbles coming out the funnel there are air gaps in your radiator caused by leaks.

If you're cheap and don't want to buy a funnel, there is a messy way to do it. When car is cold open the radiator cap, fill the radiator till it's topped off run it, it will bubble because you added fluid for only 5 minutes. If it keeps going, there is a leak. When you are done with the test, the over flow will get rid of the access fluids.

I have the same problem...But i'm thinking that its the blow by from changing oil to synthetic. I added an additive to make my oil thicker to see If that helps the smoke...its a light blue/white smoke that smells a bit sweet it doesnt sting.



My smoke comes from my breather lines tho
