oil leak from back of motor

[bill39568]

I have a decent amount of oil leaking from what looks like the back/top of both heads when I look from underneath. What leaks oil in that area that both sides would be leaking? Seems like they both started at the same time.Truck has about 25k miles on it.

it is probably a leak somewhere in the valley and then it runs towards the back and down either side. Maybe a leak from the turbo oil line or something. Clean out the valley as best you can and try to see what is leaking in there. Should be under warranty, no?

I will weed thru the valley today, is there anything else that is common to leak in that area? What is the warantee on the motor Years/mileage?

the common leaks at the back of a 6.0 are the ICP sensor, Rear Cover, or bedplate..

I looked around the top of the motor and found that the underside of the CAC tubing had oil on it by the turbo. After I removed it



I found this oil sitting in the turbo



Is this excessive? What would cause the oil to be pushed out the hose and leak all over?

[bill39568]

Anyone? Is that oil in the turbo normal?

Bill:
I have owned several turbo cars(1986 Grand National, 300ZX Twin Turbo, Dodge Cummins and Chevy Duramax). All of them have oil show up in the turbo plumbing. I have the same oil leak in my 2006 6.0 Powerstroke. My leak causes oil to accumulate on the oil filter housing and the undewrside of the hood above the oil filter cap. I understand that the accumulation of oil on the bottom of the CAC tube will cause oil vapor to spread all over. I also found an accumulation of oil on the hard black plastic hose in front of the fuel filter housing where the plastic tube clamp connects to the aluminum intake. The tube clamp was loose. Because oli is throughout the induction system, I would check all of the hose/tube clamps.
