    California Diesel Conversion Tale of Woe

    I'm doing a followup post to my original post which started this thread. I started the story. Now it is time to finish it. I spent ~5.5 months pulling the gen1 6bt out of my Dodge donor, pulling the gen2 6bt out of my Chevy, performing misc fixes to the gen1 motor, including the kdp fix (the...

    California Diesel Conversion Tale of Woe

    I would be able to non-op the vehicle and continue to store it, or raid it for parts as I see fit. As for keeping it registered, it will have to depend on the exact engine details (which I'm not 100% sure of now), and of what parts/engines I have on hand at the time. I would probably need...

    California Diesel Conversion Tale of Woe

    I hope this post helps others avoid ending up where I did... I've owned a pair of one-ton "Chummins" trucks for a a while now. One for somewhat more than a decade. One for somewhat less than a decade. I did not do the conversion for either. Both vehicles, when I bought them had California...

    Any harm in running both internal and external lift pumps?

    Answering my own question here...I found this web page to be *very* interesting -- especially the last paragraph.

    Any harm in running both internal and external lift pumps?

    I wondered about that. Like maybe the second pump -- the external one -- sucking fuel through the internal one faster than it can push the fuel. Or, the internal one pushing fuel into the external pump faster than it wants to receive it. Since the external one is likely the higher capacity...

    Any harm in running both internal and external lift pumps?

    This is for a mid-90's 6BT with a P-pump. Currently the vehicle has two tanks, each one with an internal fuel pump. There is a Summit regulator limiting the pressure to about 35 PSI. One of the pumps is having real trouble maintaining pressure. At first it seems to make 35 PSI, but after a...

    Dual rear wheel axle with single rear wheel?

    With the dual rims installed, the upward force the hub places on the axle (through the bears) is more or less straight up. The weight is distributed across the surface of both sets (inner and outer) of the full-floating bearings. When you leave the outer rim off, the force is no longer...

    Smog check...a bad omen (california)

    So I finally recvd the stickers for my two trucks in the mail today. I had appointments with the smog referee fairly early on for each of the two trucks, but I chicken-ed out and canceled them both. I was worried about what could go wrong, forcing me to repower, or modify the trucks. I...

    Smog check...a bad omen (california)

    I was worried about the complications that speaking to the referee might bring, so I'm going to try to use that as plan B. Plan A is to call back the DMV and ask what is going on. I did that and the person on the phone was clueless and not helpful with regard to explaining what happened. It...

    Smog check...a bad omen (california)

    CA DMV's phone system hung up on my after I was on hold for a short while. I called the smog referee, and now have virtual appointments set up in a few weeks to hopefully get this sorted out. It will be interesting to see (if I ever do see) what happened here, and also if anyone else ends up...

    Smog check...a bad omen (california)

    I live in California. I have a number of vehicles (can't quite count 'em with my fingers) registered and insured. All but one of them are smog-exempt because of their age. The one vehicle that isn't exempt, well, I inherited it. In California, anything 1975 and older is exempt...and diesels...

    1989 agricultural 6bt clatter at idle

    Yes, please. Adjusting the valves would certainly be easier and cheaper than acquiring and replacing injectors.

    1989 agricultural 6bt clatter at idle

    I've got a ~1989 agricultural 6bt transplanted into an '89 Chevy R30 3+3 dually, with a 4l80e behind it. Since it is an ag engine, it is governed at 2100 RPM. Awesome truck. I've had it for close to a decade now. Lately it has developed what I would describe as a pretty loud clatter at idle...

    Strange behavior, Cummins P-Pump

    I've been thinking of having a single (easily serviceable) external pump. One big downside is loss of redundancy. With one pump/tank, if a pump fails, it's no biggee with respect to getting home. Another upside is I can run a tank dry without worrying about a pump running dry while the other...
