Thank you for the informative response to my gather convoluted issue.

It is reassuring to know that TDR is available and folks have been down this road.

My first oil change in my new 2001 Dodge 3500 I used 50/50 Amsoil/Rotella. Yea I know now I should have used straight petroleum based oil for the first 15k miles to help valve seals set.

The CBV canister is located in front of the engine b4 the fan on the 2001s. Awful location in my "humble" my opinion I WOULD APPRECIATE SUGGESTIONS FOR CHANGES TO THIS CONFIGURATION.

I began to notice a rather nauseating odor in the passanger compartment. Dealer says Cummins service bulletin suggests oil from canister; those oils with ratings of CH4 or CH4+ are the likely culprits.

I feel the problem is the dumb location of the CBV canister and would like any thoughts/suggestion on this. I very much want to use straight Amsoil after 15k miles on engine.

If you read further back you will hear alot about that stupid bottle. Best solution to eliminate the smell and mess is to take the bottle out, get a 3/4" hose connector and a piece of 3/4" heater hose and run the tube STRAIGHT down and cut it off level with the sway bar. What little oil fumes escape will be taken away by the wind. No more scraping your knuckles emptying it, no more oil dripping all over your engine.
How many miles you have on your ISB now?, putting synthetic in is really a bad idea with anything less then 15-20k miles. Synthetic works TOO good and will definatley hinder the proper valve and ring seating. Also, mixing synthetic with conventional oil nullifies the whole advantage of synthetics. All that Valvoline "Dura Blend" and the other mixes have proved virtually no better then conventional oil. The original idea behind that was the hope that it would increase sales to the people who were scared to use straight synthetics since they were a "new" thing. I would stick with straight 15w-40 Rotella untill break in is complete.
