The truck's previous owner swapped heads because of bent valves. Truck ran perfect when I got it. Check engine light came on second time driving it but truck still ran good. Had it sitting idling in yard hooked top a trailer and started missing and blowing white out of exhaust. Thought it popped a head gasket. Looked it over good and found vacuum line to egr melted in two on egr tube. Ah ha. Repaired that. Thought issue might be fixed. Stopped smoking but still had a miss. Front 2 spark plugs on passenger side were wet black and nasty back 2 were normal looking. Cleaned them up and reinstalled. Still missed and started the smoking thing again. I quit on it. Was pissed. Any thoughts?
