intake oil saturated

[Isa's IH]

I pulled the intake elbow off my dad's "06" to drill/tap a boost gauge hole, I found a small puddle of oil in the intake tube bellow's, and inside the intake mani was coated in blackened oil.
I checked the oil level, it read in the half safe area when i checked it because i thought it could be using oil from the turbo seal.
He did mention to me that it has not been running right.
Could that be the problem of why it is running like that , and i am on the right track. Can the oil be coming from a bad turbo seal?
The thing is, The elbow is clean, But there is a puddle before in the bellows after intercooler tube, and inside of mani is nasty oily black!
It has around 40000 on it and is under warranty.

Is there oil coming out the exhaust? If so that's turbo seals. It not, it's probably the crank case venting into the intake. It's designed that way.

(Is there oil coming out the exhaust?)

I did not check that, But i just did the same to my "04" and it was very clean , No oil at all in the intake.
Not sure how crank case vents in intake, but it is coated inside the manifold just after the intake elbow, But puddle in the bellows before.
Elbow is clean!

Weird. I'm not sure where it is on the 6.0s, but on the 7.3s there is a short tube running from one of the valve covers into the intake. It's the crank case vent. Oil vapors and stuff get sent there just to relieve pressure of the CC.

Weird it is!

Something not right!

Hoping somebody might know what's the cause of this!?
This thing is bone stock, Bought it new!

Re-route the CCV and I believe the issue will be solved.

[Isa's IH]

How do you believe issue will be solved by doing this?

This truck is bone stock!

Nobody moved or changed anything!

Is there a service bulletin on this?

The crank case vent hose from the driver side valve cover connects to the intake tube after the air filter and before the turbo. It pulls oil laden vapor from inside the engine into the intake and is part of the emission control system like the pvc system on a gasser.

Of course if you run this hose to a filter before it goes to the intake it will remove the oil vapor and just let the air through to the intake. That is how the issue is solved. No there's no service bulletin on this. It is a system modification.

My "04" is clean, No oil in intake!

My dads "06" has oil in intake!?

What mod would my "04" have to not show any sign of oil in intake that my dads "06" does not have?

Something is not right in my opinion.

They are both stock!

Relax, everybodies trucks do this. Even your '04. If you're absolutely sure yours has not even a trace then the truck has already been modified or the valve cover isn't properly connected, it's plugged or somethin. Look at your cac boots, they oily?? Pull the hot cac tube and you'll most likely find oil. Some just have a heavier oil content than others comin from their crankcase. Lots of different reasons could explain it but theres nothing to lose sleep over.
