what could cause my truck to start smoking? on 1997 Chevrolet S10

I changed the pvc valve but it's still smoking. The oil is good.

Blown head gasket, if white smoke, running rich, if black smoke, valve guides/seals, if blue smoke.

U welcom. Just some possibilities. Really needs to be checked by a mechanic!
