White smoke in the morning then fine???????
Lately when I start my '86 w/140,000 I get a ton of white smoke for a minute, and then it all goes away and the car is fine. Also, it only happens in the morning when it's cold, not in the afternoon when I start my commute home.
What gives? No water problems.

A minor interior coolant seal leak maybe? Do you see bubbles in the filler neck? Does it go thru any coolant?
I wouldn't worry about it if it isn't running hot or using a significant amount of coolant.

No, it doesn't run hot and the coolant is fine. I started it this morning after not using it for two days and I thought someone would call the fire department. Smoke was everywhere!!! Two minutes later...it was fine.

Your car doesnt have to overheat for it to be a dying coolant seal. It just depends on how bad it is. Does your morning smoke smell sweet? If it does its a coolant seal.

All hyrocarbon fuel engines do that, especially when the outside temp is low or near the dew point. However, that initial cold exhaust condensation can mask a real problem- like a small internal coolant leak.
So, just keep doing your normal checks for low coolant and overheating.

Uh oh. You're burning coolant.

basically you have a seal that is going on its way... it could be tomorrow.. it could be next week. it could be a year from now.. but that smoke will be there till you have the engine rebuilt

I have the same issue here, it just appears like condensation from sitting outside (rains here a lot). Put your hand against the exhaust and smell it, probably smells like normal exhaust eh?
Has it rained a lot in your area lately?

Here is a test that will probably work....
Just wrap a plastic bag around the exhaust pipe, put a couple small holes in it to allow the exhaust to flow through without blowing the bad up... see if you see any water condense inside the bag.
I'll try it with mine next time I start it to see if any water condenses.
Maybe double bagging it and put some crushed ice in between the bags (so it cools down faster)?

Where did you come up with this one???
Of course he's going to find water condensing on the inside of the bag. Water is a by-product of combustion. This is why exhaust systems rot from the inside out.
dtrigg, you put a bag on your exhaust and I'll come down there myself and beat you like a red-headed stepchild.
