98s10 smoke out tail pipe

Asked by Jan 18, 2017 at 12:23 PM about the 1998 Chevrolet S-10 2 Dr LS Extended Cab SB

Question type: Maintenance & Repair

Hey guys im back again. This time i have a
98 s10. When i got the truck it ran rough but
wasnt smokeing, it had been sitting for
about two years so i figured the miss was
plugs and wires and possibly bad gas. So i
drained the tank and it had really bad gas so
i put some fuel treatment in five gallons of
gas and put it in the truck. Oh yeah i
changed the plugs to and found one faiuled.
Any way scence then it started smokeing
and pretty good (white smoke)   i looked for
a pvc valve but it dont have one.     im lost.
Any body have any ideas

Sounds like a blown head gasket. The exhaust have a sweet smell? Checking compression would be a good indication if you have 2 low cylinders. If you pull the plugs, you can see it in the plug, it would be real clean.

Unless it is a oil smell, then oil is pulling up past the rings.
