High crank pressure ???

Well lately my truck has had a nasty oil leak. I have oil puddling by my valve cover also the whole underside of my truck is covered in oil. I ruled out blow by the truck only has 190k on it and no white smoke runs like a champ. My 4x4 vaccum lines look like they are dry rotted could those lines cause that much of a increase in crank pressure to send oil out of the valve cover gaskets? also turbo is brand new. breather tube is sending oil every where under the truck. but like i said no white smoke and no sign of bad rings

Have you tried changing valve cover gaskets? When they go bad they can leak a lot of oil. Since you have a diesel, you can plug every hole in the engine crankcase and she still won't chug. You don't have a PCV valve pulling vacuum on crankcase since the intake of your diesel has no vacuum. Vacuum is created 100% by vacuum pump which dumps into the crankcase so it would do no good to attach a PCV to that. By plugging all the holes all you will accomplish is a lot of blown seals and gaskets.

I just ordered them from a local shop. How much air normally comes out of the breather tube on the crank I dont have to much comming out I can feel some blowing out but its not much at all

so i took a good look at my valve cover gaskets today and i can chip them with my finger nail they are hard as a rock. if i push on the gasket oils even comes out. my next question is my 4x4 . the two vac lines that come off the front axle that locks it into 4x4 where do the two small vac lines hook up to on the trans they run down the frame rail to the trans, also again with the front axle 4x4 locking system the larger vac line , mine just runs up to near the turbo and is plugged??
