White smoke!!!!!!

Ricks65fastback · 03-31-2009

I have a 65 289 automatic, its not over heating and the white smoke is comeing out of both exhaust. IDoes anyone know what it might be??

White is usually coolant, or very very rich (raw fuel). Does it have an odor? Sweet maybe?

it is mote than likely your head gasket, it doesnt have to be a huge break in the gasket to make the hite smoke ( raw fuel would have a bluish tint to the smoke) check your oil after it sits for a bit you might see the chocolate milk effect

Straight up raw fuel is white.

If you ever have an injector stick open, you will see that it is very white.

But I agree its probably coolant related.

I know its mainly coolent.

Head gasket(s), don't run it anymore. These aren't terribly hard to do, but you'll need a bit of parts and a whole day. Keep organized i.e. bolts screws etc, and don't rush if you decide to do it.

Even if its coming out of both exhaust pipes?

Pull the vacuum hose off the modulator (passenger side at the rear of the main transmission case). If there is ATF in it you need a new modulator. ATF burns with a white smoke. It is easy to check and a lot easier to repair than a head gasket.

If your exhaust system is a true dual system without a crossover between the pipes, either it's the trans modulator leaking through (into the intake, therefore "feeding" cylinders on both banks), or there's a coolant leak into cylinders on both sides (both heads/gaskets leaking).

If there is any connection between the exhaust pipes from each side of the engine, a coolant leak into any cylinder could emit smoke from both pipes.

Well I just checked under my valve covers and a milk shake on the bottom.

head gaskets its not a really that hard to do just time consuming, i would get all your fluids drained asap to keep from fubaring anything else
