CAC Intake elbow rubber hose

2004 6.0 F350 85,000 miles. The hose connector at the intake elbow and CAC tube is allowing some oil to leak out . Repeated cleaning R&I has not solved the problem. The part number 3C34-6C640-DA is not sold separately by the dealer , but is part of the whole CAC tube assembly for $ 250.

Has anyone found after market supplier or a solution to the leakage. Thanks

I think some reroute the CCV to stop it but honestly if you buy new ones the are just going to saturate and leak again so it is a waste of money. I remember reading a TSB regarding this and the dealer, if I recall, has direction to NOT replace if they are not cracked of split. Just one of those 6.0L things..... Gives it character. If it bugs you that much, I think Banks makes the intake piping with all of their own fittings but with out taking care of the crankcase ventilation the oil will still be there.

I trashed the CCV vent tube that leads it into the intake. A bought a rubber freeze plug kit at O'Reilly to plug the hole in the bottom of the air intake tube, and now I have a 1" rubber hose that starts at the LH valve cover and hangs down to the front axle like the big rigs. The only downside to doing that is that occasionally I'll also have that drifting oil-scented fog around the cowl of the truck just like the big rigs do when they sit and idle. It's really not noticeable unless the breeze is just right.

Keep on truckin

I've not seen to much talk of the BD CCV filter which addresses this problem, has anyone else? Has anyone used this filter and where did you mount it if you have a coolant filter on your 2003 and up 6L?
