Clogged up CDR

[Tristan]

Good afternoon all,
Today I pulled the CDR tube and adapter off the old F-250 and found the tube plugged up with gelatinous oil.

This would explain the old girl puking Oil like she was the last time I ran her. Too much crankcase pressure with no where to go. What would cause this?
My CDR was located on the intake pipe between the site filter and turbo inlet.

This should mirror the original Banks setup with the 'air box'.
Thoughts?

While this setup isn't the factory location for the CDR, it still shouldn't look like that. My first guess would be was there somehow coolant in the oil? I'm thinking maybe head gasket in the past? I know the sludge isn't a gray color, but if the issue was fixed, and the engine was just run, not cleaned up, maybe there could be a black coating on the gray sludge.

I was actually pulling it of the old F-250 to put on the F-350. The 250 was getting tired and I parked it after Oil started running out from somewhere up top after it was warmed up. After seeing this I bet the crank pressure was pushing oil out the hole where the turbo drain goes into the valley pan. After so many years that seal had degraded and wasn't sealing so well after being on there for ten years or so.
So what do you guys think would have caused the hose to the CDR to clog? Makes me hesitant to put the same setup on the F-350?

I bet you have water in your oil. Either from a leaking head gasket or oil cooler or possible cavitation. Could possibly be from rainwater, that's what you would hope at least

I believe that can also happen with a lot of short trips where the engine doesn't get to operating temp for very long.

Can the CD-R not working/placed properly cause oil leaking?

Yes, it causes great pressure in the crankcase and that pressure will either go out your turbo seals or some other weak point
