Ill start off saying i traded for an 01 f150 lifted 14 inches on 37s and it had an egr code but that didnt bother me to much so i went ahead and traded, went muddin broke a cv so i was pushing the truck pretty hard to get out, get on main road look down and the coolant temp above the H so i pop the hood and find out the battery is sitting on top of rad hose so i put it back on fill with water every things fine on way home, day or so goes by and i notice its blowing smoke out of the driver exhaust, well i think i fixed egr code passage was clogged in intake, changed the oil an it was pretty dark looking not milky though but sitting at a light and reving it up it puffs white smoke then stops, tonight i was at car wash and shined a flash light up in the tip and smoke was coming out but not to the point where you can just look and see it, looks white to me and smells rich, im not loosing coolant and it doesn't not smell sweet. From reading i have came to either valve seals, pcv valve, or rings but im unsure of what it is?
