90 S10 puts out a big cloud of smoke when first started in the morning or after sittin for a few hours. I'm pretty sure it's the valve seals leaking oil in the cylinders. Is there a easy fix or do those products that claim to fix old seals work? Or am I going to have to pull the heads off to replace the seals. I'm trying to avoid all the work because it only smokes when first started.

what color smoke?


i think if it smokes blue its the seals and if it smokes white its the rings


i might be wrong


and if u have a compressor u get the adapter and remove the spark plug and the adapter works with the air and it will give it pressure for it to stay up and then u remove the keypers and the spring and replace the seals and then install the spring with keypers

The key is he said it smokes when he first starts it up, meaning oil is leaking past the valve guides so he is right about the problem. If it smoked all day while driving, it would be the rings.

There is no "easy" fix, you must change the valve guides. I'd do a compression check and make sure the bottom end is in good shape because usually the valve guides go bad with higher mileage, meaning a rebuild probably wouldn't hurt (although not a necessity)

since you were talking bout color of smoke


white = water

black = oil


.....being burned. Sounds like oil from the valves to me too

it could just be some bad seals

That doesn't seem too bad. I never thought about that. So it sounds like everybody thinks it's the same problem, so I guess I'll get to it. Ahh I'll wait for the weather to cool a little more, shit it only smokes when it starts. Thanks for the help.

no, it's...
white = coolant
blue = oil
black = fuel (running rich)

like 5.0 said, its a waste of time to just change the seals.do it right and take it to a machine shop,and have a complete valve job done
