Oil leak at turbo connector hose.

[6.5 on da bayou]

In between the turbo outlet and the intake tube is a connector hose. Mine stays saturated with oil. I assume that the oil that is cooling the turbo bearings is getting past the seals and is getting thrown toward the intake. Anyone experince this problem? Is it a simple seal replacement or a major turbo problem?
Thanks in advance,
Floyd

Sounds like a bad CDR. Pull the hose that goes into the turbo intake boot. If it is full of oil, it's your CDR. They last about 30K mi, and when they quit, they let lots of crankcase oil vapor into the intake, thru the turbo, and a lot of times you'll see it seeping from the turbo-intake manifold connector hose. Also remove that connector hose and clean it and the pipes, then reinstall it. If you don't know the correct method for resealing the connector hose with silicone, post and I'll give you the procedure, or it's in the Haynes Diesel Manual.

I noticed the same thing when I swapped out my intake, emission stuff...so they say. You can pick one up from 50 to 120 depending on where you shop, part number cv916.

Sure. First I'll give you the "by the book" then the shortcut method. Before beginning, buy a new upper intake to intake manifold gasket. Remove the two bolts and connecting bar between turbo and upper intake manifold. Remove the two clamps that secure the connecting hose to the turbo and upper intake. Remove the six bolts securing the upper intake to the intake manifold. Lift the upper intake manifold, and with a slight twisting motion, pull the manifold from the connecting hose (hose may come off with intake, or remain on turbo). Remove conecting hose. Clean oil from connector, inside and outside of the turbo outlet, upper intake, and wipe out the oil that has puddled in the intake manifold plenum.
Assembly: Place a small bead of clear RTV silicone behind the flange on the upper intake. Carefully slide the connector hose onto the upper intake. Place a new gasket on the intake manifold. Place a small bead of silicone on the turbo outlet and carefully slide the connector/upper intake onto the turbo. Align boltholes and install the six bolts. Check position of connector to assure it's centered, install clamps. Allow RTV to set a couple of hours before starting.

Shortcut: Be carefull. Don't remove upper intake. Remove connecting bar. Remove clamps. Twist and slide connector hose carefully down upper intake until just clear of turbo. Flex hose and pull clear of upper intake. Clean hose and surfaces. Apply small bead of RTV behind flange on upper intake. Carefully slide hose on upper intake to just clear turbo. Apply thin bead of RTV to turbo. Slide connector onto turbo . Rest is same.

Well
The hose going to my intake boot was full of oil. I can't find a CDR locally so I will order one from SSD on monday. I will let ya'll know how it works out.
Thanks Husker 6.5

i replaced my CDR about 5,000 miles ago. when i just removed the filter to clean it a week ago and found oil on the lip of the turbo. I thought the CDR would last 30,000 miles? Is the oil going to cause any problems?

A small amount is normal. If it's moving a lot of oil it needs replaced.

On SSD's Web site, under the maintenence tab, it says every 3000 miles. HAS to be a typo. In the CDR details, it says 30k miles. Mine has never been replace now going on 142,000 miles.......oops:eek:
