well as most of you know my dad bought a 95 cmaaro v6 3.4 and there was some white smoke comming out the exhaust when you first start it up. Well i thought it was burning oil but it does not smell like oil, almost smells rich. I just replaced the fuel filter,s-belt. and all 6 plugs and wires and cleaned the throttle body out. Well when i pulled the plugs out they were original with 99,000 miles on them. But they were not oil fouled at all. They were real clean except they had a little of a white color to them what does that mean? It runs better now but it still smokes a little when you first start it still.

white plugs means there running hot, ie lean. Or as stated, white smoke out of the pipes = antifreeze. Know waht an old school trick used to be for cleaning cylinders of carbon deposits? A couple drops of antifreeze in the plug hole, and crank her up, viola! cleaner cylinder.

if you have a high compression motor liquid in the cylenders is a very bad idea. it dosnt compress and you got huge problems. plus when water mixes with a lubricant its not a lubricant anymore

I know, that's why I said old school, so don't anybody go and start filling your motor up with the stuff now.

Dont bother with the old school tricks like wright said, or pouring water into the engine while its running.

Just run sea foam through it.

People,

I said it because he said the plugs had white resude, IE, possible intake manifold gasket leak!!!

Never once did say go dump a gallon of anti-freeze in motor. I said that' s what we

used to do
