It's been a while since the truck has had me this stumped. It used to take a splash of oil every 4-600 miles to top off. Now it's going through the operating range in a little more than 300 miles. I have tested the CDR/blow-by using Heath's way, and it checks out fine. I can't see any obvious (fresh) leaks on the underside, and there's no more blue in the exhaust than a normal diesel "hint" of blue that comes out with black smoke. I also can't see any oil leaks possibly from the cooler/lines either. The oil's going somewhere, but I don't know where.

8. Condition of Battery terminal connections (removed, cleaned and tightened)
One changed, other three clean
8a. Known condition and age of the batteries.
N/A
8b. Are batteries of differing age or are they a matched set?
Appear to be matched
8c. Condition of Major Grounds. (same drill as batt - removed, cleaned, retightened)
Seem to be fine

4" exhaust
23. Upon unscrewing the fuel cap, do you have a large vacuum formed in the tank? yes/no
Yes
24. Location of PMD/FSD? On the pump/remoted over intake/remoted out of engine bay (please specify placement specifically)
On front skid
24a. If remote mounted, describe wiring harness (homemade or purchased from a vendor?)
Heath
Now, I know that I need a new fuel cap, and that the 35 and 36 indicate a bad IP, but I'm in no hurry to change the IP, especially since the truck is running so well. I have also found a possible culprit to the 33.
So, if anyone has any ideas, please, any help would be appericiated.
