Re: 6.2 squarebody banks info!!

Diesels have a LOT of blowby. They will pressurize the crankcase and start pushing oil out everywhere. Since venting them out is bad for the air, and covers everything in oil, they need the equivalent of a PCV valve. Unfortunately they don't make much vacuum. The solution is the CDR, which regulates crankcase pressure to manage the blowby and oil vapors. Hook it up correctly. It may help if you flush it out with some gas.

Suggested reading http://www.dieselhub.com/maintenance...cdr-valve.html Note this is factory 6.5 turbo set up, but the Banks (aftermarket) is very similar.
