Having problems with your Ford F-350 ?
I have oil blowing out of the air cleaner and the dip stick tube. I allready changed the plugs (non were black)the truck does not smoke out of tilpipe. I disconected the 12v activaded canester on one side of pcv valve. that made it stop smoking a bunch. so i think it is something to do with the smog system?
A clogged PCV valve or EGR valve is what I'd think of - mainly the PCV valve. Replace it along with any hoses that feed it or that it empties into, since if the valve is bad, or sludged up, it's likely that the hoses have a coating of oil sludge inside as well. A bad PCV will cause excess pressure in the crankcase, leading to oil leaks and losses.
