White smoke

Howdy All! My 94 Caprice Wagon LT1 is running like a top, great power all good. its getting warmer finally here in Chicago and I noticed heavy exhaust smoke( tolerable not horrific) especially out of the passenger side. I thought it was from cold weather. Now that it is nicer out I am noticing it. Looking Online I see a range of issues from fuel filter to bad head gasket. The car runs great and wondering if i should just deal with it or get it checked out. Any experience out there.

This is going to sound stupid, but go out back and smell the exhaust. Does it smell like coolant, oil, fuel, or just exhaust?

Smells like exhaust.. I have read if its smells like coolant it would be a head gasket, it just smells like exhaust. and you have to get real close to smell it.

At this time of year it could just be condensation boiling off in the exhaust system, but that usually fades after a good run. White smoke usually means moisture (including coolant), blue is oil, black is fuel/misfire.

One sure sign is coolant consumption -- if coolant is mysteriously disappearing without leaving puddles under the car, then maybe it's going out the tailpipe. A check of the plugs may reveal which cylinder is involved. A significant leak into a cylinder will usually cause misfire issues, and may cause hydro-locking, especially when attempting a restart when hot.

I agree that it is *just* condensation. Light white smoke is normal for most cars, LOTS of smoke is never good.

Simple check is to check out other cars on the road as you stop at a light. Do some of them smoke just as much as you? Do you smoke more at idle, under acceleration, or does it stay the same?

The answers to these tells us more about what can cause the issue, but I am leaning more towards the cats not burning off the exhaust. And that is a *non* issue.
