smoke @ startup

my 1995 rodeo blows out heavy smoke on start-up after sitting 2 days or more---i think i have a bad valve guide?
any suggestions?
runs perfect after getting warm and oil burns off
just passed pa emmissions test 1 mounth ago
is this normal
truck has 110k
plugs dont seem fouled--but havent pulled yet

trent out

Two very important questions...

1: What colour smoke is it?
2: What is the tempature outside, and does the smoke dissipate when it is warm outside?

Trent,

My 3.2 does the exact same thing, it is probably worn valve guides or valve guide seals. The solution is to have the heads rebuilt.

the smoke is grayblack---doesnt seem to be black/soot
end of pipe isnt black
temp in the 25-50 range--smoke disapates rapidly=seconds
no pm 10
could it be excess fuel?
o0r oil

oil would leave a black pipe end

Yep...certainly sounds like valve stem seals gone bad.

Eventually, you'll probably want to have the head rebuilt, but for now, just watch for oil level.
