91 s10 blazer smoking

[caddiblack]

I have a 91 s10 blazer that I bought about one year ago. I have been fixing it up. New interior, caddi tail lights and a few other mods. This truck ran fine when I bought it. A week or so ago, I started it up to get it ready for summer and it has been puffing out a nasty smoke. I am a body man, not much for engines. I know the basics, oil chages, thermostats, spark plugs and so on. I have done everything on this truck and would like to fix this poblem as well. If anyone has any ideas please reply. I looked in the hanes manual, but it really dosen't touch on this problem.... Thanx

What color is this smoke? White, black or blue?

I would say the smoke is mostly white. It has a little tent of grey or blue, but is mostly white. Any suggestions?

White smoke is usually transmission fluid or water. There is usually some clear water coming out of the tail pipe and muffler drain hole, this is normal. After sitting for a while, sometimes moisture will accumulate in the exhaust system. This would clear up after about half an hour.

Is there any residue in the tailpipe? An oily residue could mean that a vacuum hose is sucking trans fluid, possibly from the vacuum switch on top of the transfer case.

Does the smoke have any odor. A sweet smell would indicate antifreeze. As in intake manifold gasket or head gasket.

In my 91 i always have the billowing puffy white smoke. I tried fixing things to make it go away but what i did usually made the rig run better so i write off the smoke. When i replaced the old muffler and put the new one i cut down on it alot because the old one was clogged with black stuff.

Thanks a lot for all of the replys. I had a friend come over and he is certain that I need to replace the head gasket. I ordered a gasket kit and he is going to walk me through the install. I always like to learn more about my s10. If anyone wants to know how hard it was to replace the gasket, email me in a couple of weeks, maybe i'll have a trick or two too pass on. [email protected]
