92 f150 high milage but never any smoke nice and tight...now its smoking like a train and so much crankcase pressure it pushed out the pcv outta the valve cover and the dipstick pushes out ...the air filter box is soaked with oil and gas ??? could this be some bad emission componets not working correctly egr etc ??broken ring ?? valve seals ?? it's a 302

 

I would suggest a compression test of all the cylinders and go from there.
You may even find a clue looking at the spark plugs when removed.
An engine that is overfilled with motor oil can give the same result.
