Default White smoke billowing

I have developed a sputter at throttle, small amount of white smoke coming from the rear upper passenger side of the engine. LOTS of billowing white smoke out of the exhaust. Had a little bit of sputter a few days ago, and the car got up to about 225 or so. Shut it down, added coolant to the overflow tank, and it'* been running without miss or overheating since. Today this new problem started. I'm almost afraid to drive it now. Can anyone assist?

White smoke is normally coolant (right smart people).

Possible intake failure?

It appears to be coming from right around the "corner" of the valve cover area on the back side.

As for the maroon, it'* a really faded color, therefore the comment in the sig.

How many miles are on it? Sounds like your lower intake gaskets have failed. Not uncommon on an engine with high mileage.

C'mon Mos, you're just jealous cause you didn't think of it first!

Seriously, and this is pretty serious car trouble - don't drive the car anymore! Check the oil for evidence of coolant - if the oil is milky or full of bubbles of coolant, drain the oil right away.

White smoke out the tailpipe means you are running coolant through a combustion chamber. If the leak is bad enough - and it sounds like yours is- you could destroy your engine the next time you try to start it.

Vital is probably right, you probably have an intake manifold failure of one sort or another.

You can pull all the spark plugs out and look for evidence of coolant. With the plugs out, turn the motor over by hand and see if any coolant comes out.

Lots of threads here on manifold failures for you to search and read.

Sorry it ain't better news!
