Transfer Case Leak Prevention (http://www.thedieselpage.com/reviews/tcase.htm)
Product Review: For several years now, we've been hearing reports of transfer case fluid leaks due to a wear-through on the rear case half. If not caught before a leak develops, the transfer case could suffer complete failure due to a lack of lubrication. The most reliable solution includes installing an aftermarket part that prevents a case wear-through from happening. Follow along as we show you the problem and describe what it takes to produce a permanent solution.


6.2L/6.5L Diesel
Crankcase Depression Regulator
The Crankcase Depression Regulator (CDR) has been a part of the 6.2/6.5 diesel emissions system since the first 6.2L diesel equipped truck rolled off the assembly lines in the fall of 1981. The CDR's primary purpose is to maintain something less than 5" of water vacuum within the crankcase. We sacrificed a perfectly serviceable CDR by cutting it apart to have a look inside, and to show you how it operates.
