I hope its good things your learning!
That cracking looks rather typical honestly. I don't run Bio in my stuff, it's hell on everything from my experience. I run #1 or #2 or waste oil. Heating oil, Jet fuel, I just polished off 125 gallons of hyd fluid. If I run #1 or #2 I run a quart of outboard mix oil each tank. I don't do additives, I see no need for them. If it's real cold I use Kerosene to thin the fuel, it's still the best anti gel made. Phil your head looks like it needs a little guide work. Pretty normal in a old Cummins. Patch I noticed had some antifreeze running down the pass side block coming from between the block and the head. The last 10k miles or so it's used about a gallon of coolant a month. I torqued the head bolts "tighter" and it has stopped for now. That engine just clicked over 429K so it's about due for a head job.

Hey Norm,Based on your experience which is pretty extensive from what I can see, how about posting a small recipe or chart or writeup or something of your fuel mixes.I have used XPD since new, but my fuel gels every single winter. Never tried the kerosene formula. I have to wonder if the modified fuels will work the same in the modern peiso-electric super high pressure injectors the same as a dirt floor VE or P-Pump Cummins.I see where you add a quart of 2 cycle outboard per fill up. 30 gal fill up?? More?And how much kerosene per tank or gal perhaps?I think this is some good useful information here.
Phill can you flatten a tire, re air it and use a stop watch for us? I have been debating compressor plans on a truck I am piecing together out of junk Dodge parts. I could use a York for OBA, but it's a lotta messing around on a Cummins.
I'm gonna fit a mini York on the dmax when I get time. I like the thought of having a "real" air compressor. I have an arb right now and it's pretty loud, and draws a bunch of power, but gets the job done on the air bags.
That sucks. How much pressure did you test it with?
I went up to 30psi, but the intercooler leaks bad at 10psi. This I hope explains why I am only getting 20psi of boost!
I put the dual 440C Viair compressors on my Dually for on board air. Drives a 5 gallon tank at 175PSI. Runs air actuated bottle jack when needed, inflates tires, train horn and air bags.I want an OBA system for the LB7. I'd be curious to try a york compressor but I don't know specs on volume and pressure compared to an electric..

JB weld? LoLI am glad you found that issue. Now all you need is a inter-cooler and your back in business. That tester is pretty slick, much simpler than going to the car wash and spraying things down with fruity smelling soap while your wife floors the Cummins looking for bubbles.
Hey man, don't laugh...I currently have not one but two JB weld repaired intercoolers. The one on the John Deere that was harpooned by a locust tree, and the one on Square D. Now granted the Square D one hasn't retained any pressure other than atmospheric, but it sure looks strong!
