Turbocharger leaks oil from intake manifold hoses

[isa540]

I need to change the Y pipe couplers [the hose providing connection between intake manifold and engine connections] on my 1999 7.3 powerstroke. The existing hose is leaking oil and need to be replaced. Are they difficult to change? Also, where did you buy the replacement hoses and the O-ring? The dealer’s price is about $168 for both of them not including the O-ring.
I don’t want to compromise on the quality and the reliability of these connection hoses, so do you guys recommend I buy the parts from the dealer or buy after market parts?

Thanks in advance,
Isaac

Hoses and O rings??? Not sure I'm following you and I know the 7.3 turbo like the back of my hand it seems at this point...

The only O rings are on the bottom and top of the pedistal.

I don't know of any tubes or hoses on the turbo???

There is a map line that comes from the map sensor over to the front of the turbo. That's just standard small diameter heater hose. There is a wastegate line that's red that splits at the front of the Ypipe, and there is a green line that goes from the Ypipe over to the intake...

hose or lines coming from Y pipe that attache the intake manifold to the engine--where the compressed air enters to the engine. Actually I took my truck to get camshaft positon sensor changed [the recall issue] and the technician alerted me on the problem which he said it wasn't an urgent issue but i should get the hoses changed. It's the orange colored line--hose-- that goes from the Ypipe over to the intake. Also, as you rightly suggested the peldestal O-rings that need to be changed.
Are they difficult to change and do we have any torque values as to how tight we should tighten the spring clamps?

Subbin.... did not know there was oil going there. I thought that was just air movin through those holes.

Can you post a pic?

i think he's talkin about the oil from the ccv that gets blown through our intakes. dieselsite.com, or dieselpowerproducts.com sells the boots kits

OHHHHHH

Ok those are called "boots"

For 100 bucks you get 4 of them from www.dieselsite.com

and you get new zinc plated spring clamps.

Don't buy factory ones - they break down from oil over time and cause boost leaks.

thank you for the info, this was exactly what I am looking for, the original boots [now I know they are called boots] had cracks on them causing the leaks, well they are 9 years old so its time to change them. I will order one set soon from dieselsite.com.

The reason they break down over time is because of the oil you're seeing. Consider doing a CCV Mod if you are going to change your boots. It keeps the boots clean and oil free as well as your engine compartment. NCHornet sells a great kit.
