    I would buy straight from Cummins or a dealer(which ever is better priced)and go recon or brand new. @SmokinCAT knows a reputable shop that does good work. Hopefully he chimes in.

    PX , not RX though. Both are reman but PX is the better way from what I know. At least as far as Cummins genuine is concerned
     
    Dave_in_AZ and BoxCarKidd Thank this.

    Is there a large risk of him continuing to drive for the next two days until he makes it to the shop? Last thing I need is a broken crank because of uneven combustion or that sort of thing lol.
    Also, how do you identify the type, as is PX and RX?

    Well the PX, RX request is made while ordering parts. If you request injectors, chances are tgey’ll Supply RX. If you request PX, they’ll have to search a bit harder. PX/RX is part of the actual part number. Remanufactured, vs PX. Your basic reman is an RX part number. RXxxxxxx etc. if you’re aware and ask for a PX, just look at your box the injectors come in, check the part number, check for the PX prefix, the “PX” before the numerical part number.

    Thanks for all the help. Driver is about 100 miles out and I've got some shiny new PX remans in hand. I've got a couple of question about install, I was reading a thread here and it was recommended to clean the injector cups, how exactly do you do that, I'd assume that steel wool would damage it so would a nylon bottle brush work?
    Second question is how do you evacuate the fuel in the cylinder to keep it from hydrolocking?
    When I swapped 1 and 2 no fuel came out or very little due to the whole algea clogged system, but that issue is fixed now and I'm assuming that when I pull the first injector the cylinder is going to flood with fuel. I've been thinking of using a shopvac but I don't have a nozzle that small so id have to rig something up, what's the usual procedure for getting the diesel out of the cylinders?
    Lastly , do you grease the orings or just wet them with diesel on install?
     
    Dave_in_AZ Thanks this.

    Here’s a video I did one setting the valves, injectors. Can’t help you much with the install as I have not done it before personally. This video is okay, I say the right stuff but it’s painfull to watch because I didn’t know what I was really doing.
