How long since a tune-up? Any applicable trouble codes? You should be able to check mil codes, yourself. What color was smoke, if black, check fuel system. It might have been trying to flood?

I just bought it from a private party a week or so prior. Oil is fresh and is at the right level. The check engine light was randomly coming on while it ran good but that i believe was just the oxygen sensor. The smoke was white or grey i believe. Hard to tell driving down the freeway. What do you mean by trouble codes? How do i check mil codes? Thanks for your help.

You use a jumper wire between A & B terminals at the datalink connector. Turn key just till dash lites come on, no further. The mil lamp on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes.

If smoke was white, maybe coolant getting into the cylinders? Are you losing coolant?

I did check the coolant and it has went down alot from being full before this happended. If thats the case and i am getting coolant in the cylinders, is it pointless to fix and bring it to the junk yard or what are your thoughts. I have $800 in it and its a very nice truck until this happened. What would you do and what would i be looking at to fix it. Thanks for all your help

Might be a bad gasket, or the head / block is cracked. Can you do a compression test on the cylinders?
