03 4.0 sohc running fine then shut truck off and started it a half hour later it seemed to have no power when taking off, checked it out and there was oil coming up from my valve cover vent into my intake and burning in my exhaust, thought it was pcv? so i replaced it still having same problem of no power, truck idles great starts kinda hard, revs up really slow even when warm, and have to use 1st to the floor to take off without stalling,

 

i guess everyone else has the same anser i do nada

 

still have this problem going on its pullin oil through the valve covers into the intake and air filter alot in a little time maybee a crack in the head i dont know what the deal is

 

Do a compression test. You might want to take the oil fill cap off while its running, and see if there is an excessive amount of blow by.

 

Interesting problem, wish there was some feedback. Kinda hard to offer any more suggestions without it.

 

ur telling me i still have had no desire to even mess with it yet but ive got to do something soon
