2006 350 lariat with 6.0, before the job truck ran fine but was leaking all over from the lower pan to the heads, valve cover and oil cooler. When I took everything off the valves and pretty much everything on the intake side had enormous amounts of build up.(truck has a delete) replaced the following gaskets, heads, exhaust, intake, oil cooler, oil pump, o rings on dumby plug and pick up tubes, valve cover, valve seals and fuel injector o rings.
I had a minor issue in set back and a valve bridge popped off trying to get it to run. Put it back on and the truck runs sounds “ok” maybe forint air out still. Put it in gear and it seems to bog down slightly and the pitch or the engine goes kinda shaky.
When in gear not pushing the pedal the truck will move push the pedal and it wants to die and blows black smoke. Oil pressure is good but I seem to have no boost pressure, or at least not at the gauges. Could I possibly have a stuck valve? Do I need to scan this or open it back up?
