Cloud of Exhaust after start up
So this has bothered me to the point of doing something about it. I've got a 95 4runner auto 3.0 that I've had about a year. In the morning I let it warm up a minute before I take off and find theres a lot of exhaust after about 30 seconds from start up.
I really notice it at night when I come to a stop light and it catches up to me and billows past like a cloud. It smells fine and is a whitish color. I baby this truck and really only is driven a few miles at a time in town.
I think a tune up will be done soon to keep everything running smooth.
Also saturday I'm doing the airbox mod and giving it a good wash and wax. Anything else to check while the suns out? Thanks

Well, my best advice for you:
If it still runs strong, and doesn't smoke too bad all the time, and if your problem doesn't affect your performance, you'll be fine......................
For now.

If it's white then it's water. So, it's either the headgasket or just build up of condensation in the exhaust after having sat long enough to cool down. The condensation smoke (steam, rather) should stop, though, after everything...motor and exhaust system...has gotten substantially warm enough to burn everything off. But, if it's the headgasket/s, it won't stop. You said it smells fine? Meaning it doesn't smell like coolant? Why don't you have a peak in the radiator or on the oil dipstick for contamination? Have you noticed any loss in power? And how long has this been happening? (I ask the last question because it IS getting colder and it's quite normal under the circumstance)

I have a similar situation. but not really. I have an oil leak, but I only get a slight puff of white smoke thats very thin when I first start it, it stops after about a second. I don't know if it's always done that, but my friend pointed it out the other day, so if mine has to do with the same thing.

Well, I can tell you that it probably didn't do that when it was new...I dunno, sometimes if I park on a hill, I get some smoke out the tailpipe, too. I don't think much of it. It's just a fact of life, I've got almost 200K on my 4Runner. It runs fine, and that's what really counts.

White smoke...steam...it happens even with new cars...even if it's almost imperceptable. Just depends how efficient a vehicle is or, more often than not, enviromental conditions....like humidity and such.

Enjoy the sun while it's there. The North west's sunny days are numbered...Why do you have sun and California doesn't? I don't remember seeing anything in the paper about there being a cold day in hell...JK You just enjoy it while you got it. The weather in Northern California sucks for the time being, so I guess I can expect some sort of Seattle referances from the folks in So Cal.

This is the answer I was looking for, the others kept me tossing and turning last night.

White Smoke from Exhaust
I know its old school but if you were to have a HG leak and coolant in your system then the white vapor would smell really sweet , dead give away for vaporized coolant in exhaust .
If it goes away after warm-up and your oil is clear (not whitish from water) as well as coolant level staying normal and no oil traces in coolant then your just dealing with condensation and with the weather braking to winter that will be much more present with cooler temps
If your really paranoid about it then run a compression test , that will tell you

all of my cars or trucks I have had did an do this on cooler mornings and it was just condensation,
now I did have a mazda that had a bad piston ring or valve seal
and in the winter mornings after sitting all night oil leaked into the cylinder and the truck would burn oil for 10 minuets until it warmed up and when I say it burned oil you could not see the truck running in the front yard if there was no wind looked like the house was on fire.
is it cold where you are at?
