I am seeing and experiencing the problems all of you are talking about with the current stock crankcase vent and bottle. I am thinking about trying what I call a crankcase vapor condenser. I do not think it would work in those situations where the down hill angle would cause the oil to flow out. Following is a posting and update that I have put on a different diesel forum.
OK! OK! Don't laugh me off the site! And I have the empirical proof! Unfortunately, I am not able to find the link any more, if I do I will post it. Basically, you make a condensation jar and put it inline of your PCV vacuum. For us GM dieselers this would be inline with our CDR. I have had one on my daughter's 92 Ford Ranger (my previous truck) for a few months. We have not seen ANY increase in mileage, and did not expect any even though they mentioned you would. And the first time I checked the jar there was about 1/4 cup of very dark oil/fuel. It did NOT smell at all of gas! So, I ignored it. The oil was changed and the other day I happened to check her oil. It was as clean as FRESH oil! And it had been about 1200 miles! Never, never seen that before on that vehicle! I am impressed and will continue to monitor it and report.
By mistake (my daughter's mistake) HER '92 Ranger went 7000 miles on the last oil change and the oil on the dip stick was still only a dark honey color. There was about 1 cup of really black oil? in the sludge jar with some moisture and the beginning of sludge in the bottom. I am convinced - at least on a older gaser. Never, never seen that before on this truck. And currently, it is running smoother and the spark plugs are staying cleaner.
After seeing what it did for the Ranger and seeing how black and how quick my truck's oil goes black, today I put the sludge jar on the Silverado. Again not expecting much. Some black oilly stuff in the tube and hose connections. Started up and checked for vacuum leaks - none - of course, very low vaccum at idle. Now, I start up and drive to work. After 3 miles, the engine quiets down like I have never heard before - down the road and a idle! At idle the engine is quiet and smooth! It is scarry! Something BAD must be about to happen! When I got to work, about 12 miles, I left the engine idling and popped the hood to check for something leaking or broke but, everything was fine - just a smoother, quieter running engine! It will be interesting to see how the truck starts up and runs tonight after work. It has started well in the 6 weeks I have had the truck.
The quieter operation of the 98 6.5TD turned out to be old diesel vs fresh diesel. The sludge jar on the 92 Ranger gasser is still there and still working very well, keeping the oil basically clean between 5000 mile changes. Collecting about 1/4 cup dark black something and some brown sludge in the bottom - oil and water obviously. I never got to fully check out the operation of the sludge jar on the 98 because I sold it to my brother who traded it for a newer Duramax!? I have subsequently put one on the 93 Silverado 6.2L diesel (no turbo) I have and can report that after about 2000 miles there was about 2 tablespoons of black syrup in the bottom. The oil is still rather black though. Probably because the crankcase, oil cooler and engine have not been fully flushed and I probably have some blow-by in this 93 with 184K miles - still runs very good though!
I am going to try one of these on the 02 2500 CTD that I now own. But it may take me a while. If anyone is game I will send pictures and help with description. I will have to plumb into the intake pre turbo and the BBs (or steel gauze) should condense out the majority (all?) of the vapors that would coat or gum up the turbo like it does on the older 6.5 TDs on the Chevrolets.
I have pictures but do not know how to attach them here. I do not know if the link below will work but there are images in the 4th entry down.
