Oil in intake between filter and turbo...??

Where is this oil coming from??? Its inbetween my airfilter and turbo. Is it from the breather? I assumed it was from breather so i flipped it around and disconnected it from the intake. Might pud a pod over it...

what is the cause for sure and how do i fix?

p.s. i have the airbox delete.

Yes, its from the crankcase. Do a search on CC mod, there is lots of threads on it.

crank case?? Do you mean the heads? The breather is ontop of the valve cover.

Yes, we call it a dog house. Turn it around then run a hose over the vacuum booster and then down to the frame someplace. Over the vacuum booster will help any oil to run back into the valve cover and not drip out the end of the hose.

If you don't have an intercooler, just leave it in the intake. It will not hurt the turbo.

I was just thinking of putting a breather filter ontop of the rubber elbow. I already flipped it around.
would that work?

I built a catch can and mounted it behind the cab then I rand the hose to the rear bumper area with a screened filter on the end. I don't get any oil in the catch can but I do get some drips near the bumper. I may move the can to the rear and see if it will catch it there.

I left mine connected since it keeps the turbo and intake from corroding

That will work, but two possible problems. The filter is probably going to get saturated with oil and you'll have oil vapor residue all over the place under the hood. The other reason for routing it to the rear of the truck is that the crankcase vapors stink pretty bad. You might be able to put up with it but if your wife or girlfriend rides in your truck they will pifch a fit.

Its a little difficult to keep the line sloping down all the way to the rear. If its not at a angle down then the oil might pool in a spot and block the line.

at the moment it looks like my engine is smoking at a stop...its coming up through by my windshield wiper. Also yes it definetly stinks and my fiancee has already comemted on it. I probably will do the: over the brake booster and then down. Probably wont go to back of truck though...if any...just behind the cab. Worrried about plugging it up though when i go off roading...so more likely will just bring it towards the bottom of motor.

One of the earliest effective air pollution devices was the CCV. I remember the days before they were around, and the engine often smelled like an oil refinery both under the hood and outside.

Unless you have an intercooler, why discharge this oil pollution into the atmosphere?

because my engine and front of my chasis is already fairly oil caked. I am trying to reduce this and clean it up. Because whenever i work on it i get covered in sludge. It also looks nice clean.

The CCV shouldn't be the one causing oil on the engine. If it is, then you have a leak on the intake or boost side of your turbo which is a bigger problem than a little oil leak.
