Why did my truck shoot oil out of the tail pipe... I went to do a pcv reroute.. I thought well why do a T and run it under the truck ? So it can cause any smoke ect,, Well i did a 5/8 hose from one side valve cover to the other .. Let me tell you what, big white smoke and oil every were, it was like a fire hose blowing out smOke and oil ???????????????????????????? Why

now you have a ncv lol. you need to tee that line and run it to atmosphere. all that pressure youre building has to go somewhere and thru your turbo and out the exhaust it went

You should have put the T in the line and ran it down under the truck, the engine did not have any where else to vent to so it blew it out the tail pipe

PCV -- Positive Crankcase Ventilation -- used to vent the pressure buildup in the crankcase (some cyl pressure does leak into the crankcase when engine is running)

You tied both sides together instead of venting to atmosphere, so you had NO venting at all. Pressure kept building inside the engine case, and it eventually has to vent SOMEWHERE, in your case out the exhaust (maybe thru the EGR system?)
Time will tell if you hurt anything, you're just lucky you didnt blow out your main seals.

But dont come on here and blame the forum because you didnt know what you were doing.

I see spare part.. i dont mean anybody any harm im not a hateful person this is the first time i ran into such .. he may have took what i said the wrong way im 6,5 240lb i dont worry much.. If you were offened im sorry about that wasnt ment as a poke at anybody or the forum..... BACK to the wild oil job i gave my self .. xmadmax the turbo was smoking slightly like if you were to have dripped oil on exhaust pipe not big smoke just you could tell look kinda like oil dripped on it ... do you think i hurt the turbo if it did ..god what a dumb thing to do.. Never would have guessed plugging them together would have done such a mess

Check and see if you ahve any shaft play on your charger. If so I'd say your bearing in the turbo is where the oil came from. Thats a guess but worth looking into
