    Jesus Freak's WMO IP thread

    It's the soot in the wmo. Sub micron in size and highly acidic and abrasive. Regular fuel has none, and coming from a refinery(distillation) it's a pretty clean product(compared to wmo). The only contamination would be what's introduced after the process, which would be dirt or other stuff from...

    back prime the fuel system?

    I wouldn't. That schrader is after the filter and would be filtered fuel. I assume you won't be filtering the fuel that your inserting? Pushing fuel into there will only fill the filter and line to the injection pump. It won't do anything for the IP or the injector lines. Cranking it while...

    Repeatedly bad u joint

    If it's continually shearing out the axle side I'd check the yoke on the pinion for damage/bent. If it's out of sorts at all it'd create a weak spot, that being under acceleration, loaded, up steep hills will continue to find.

    Repeatedly bad u joint

    Any pictures? How's the needles look? Too much of an angle will give a harmonic shake and noise, same with mismatched angles. Too little of an angle and the joint doesn't move enough and the needles will pound flat and then fail, especially if your loaded heavy. Put an angle finder on it see...

    650cca vs 850cca group 65 battery

    Then buy what you can. FWIW, I know of guys that buy and use batteries from the junkyard. They typically get them for 20 bucks. If you can get a good pair of them from something that was wrecked, you might be better off there then spending over 120 at walmart.

    Jesus Freak's WMO IP thread

    That screen being clogged is unusual. I've read that "cheap" filters will have that fibrous material left over internally due to the manufacturing process. It's actually filter material itself, leftover from being cut down to size and then caught in the pleats when they're folded. This was on...

    Cheapest wmo setup

    Here's the link for anyone else curious. https://washingtondc.craigslist.org/mld/cto/d/elkridge-1989-ford-350-tow-wrecker/7571743801.html Is that a cracked frame in the 8th picture between the spring perch and trans crossmember? Around here trucks don't sit. Guys will run them in to the...

    Fuel filter light comes up what could be the cause?

    Either the vac switch is bad, or you have vacuum in the filter. Plugged filter, bad lift pump, kinked line, failed fsv, plugged showerhead, etc.......

    clarification; early IDI oil cooler bundle vs. late IDI cooler bundles

    Tabs are the same between turbo and NA IIRC. At one time you could get both na and turbo bundles, and then you could only get turbo bundles. During covid you couldn't get any, and a lot of parts stores sold power stroke bundles as a mistake. Now I see ford and IH both have turbo bundles...

    Aftermarket Fuel System Mismatch CDD and R&D

    Why? So long as it's objective and factual, and not opinion, I don't see how they could get upset. Keep it clean and insult free, and I don't imagine you'll have an issue.

    “The 6.9” project thread

    Yeah, the 50 was too small. Don't get me wrong, I still rode the hell out of it, but felt like a circus act while doing it. I'd say a 110 would be perfect.

    IH Loadstar 1700 diesel eng guidance.

    I think the bigger question is what transmission are you going to use? All 3 engines can be made to work. But if you're going to need both pull 30K lbs out of the field, and drive from NM to NY, you're going to need quite the spread of gear ratios. After that, I likely wouldn't choose any of...

    “The 6.9” project thread

    I know where you're coming from lol I did some carb work on and then flipped a honda crf50. I kind of regret selling it because of how well it ran and much fun I had toying around on the thing.

    My options, and your opinions.

    I reluctantly agree with this. A large number of techs in my experience do little diagnosing. A lot of shops charge the diagnosis fee in order to cover scanner costs. Our newest scanner offers a feature that gives the most to least changed components per trouble code. Makes it too easy for them...

    My options, and your opinions.

    Yeah, this isn't an 8n or a model t. Most rebuilds/machining needs to take place in some sort of shop for it to be done accurately and correct.

    My options, and your opinions.

    I don't think the heads between the 6.9 and 7.3 are the same. I don't think the bolt hole diameters are the same, though I've never put a caliper to them and checked either. I know the dowel pins are different between 6.9 and 7.3, so I don't know how the head bolt holes wouldn't be. Did your 6.9...

    oil pressure regulator

    I don't think you have to pressurize that port to test it. Just have a hole in your plate where the valve is. Pack the valve with grease, screw a filter on the head, then pressurize the oil side of the equation until you get air out the hole. I assume your plate can pressurize the oil side? they...

    Magnafluxing Heads - Where to Check?

    Precup cracking, so long as it doesn't extend past the fire ring, is okay. Any crack in the head is no good. Check the normal areas like between valves, valves to the pre cup chamber, and valves to bolt holes.

    oil pressure regulator

    I haven't. But aren't you the guy that has the steel plate to test oil cooler assemblies for leakage? Wouldn't take much more to add additional ports and use an air pressure regulator to see what psi it opens at. If you aren't, the picture I saw used 1/4" inch steel plate that held the 2 ends...

    anybody ever had a torque converter get stuck on the engine?

    I've had that issue before. It was on an engine that sat for 40 years though, and the converter wasn't going to be saved or reused. I was concerned and wanted to reuse the crank. I first drilled a hole and let the fluid in the converter drain out for a day(there was still some in there). Then I...

    Injector pump longevity

    More do it then you might think. I believe they run it under a vacuum, so no explosion risk there. Some have even tried to do it with plastic, but I feel you'd have to chemically break it down to a liquid first before heating/distilling. A guy locally to me supposedly has a patent for it, but...

    Injector pump longevity

    We burn all our wmo in the oil furnace at the shop, my goal is to burn wmo as a road fuel, but the only diesel vehicle I have is the school bus, and I'm not about to daily drive that. Eventually I hope to build/buy a diesel powered car/wagon or truck, anything that's shorter then the bus...

    Injector pump longevity

    Pumps do not turn the same on a 6.2/6.5 compared to 6.9/7.3. They hashed that out on the other thread. I'll clean the info up for anyone else reading or searching. Both cranks turn CW when viewed from the front. 99.9+% of RWD vehicles do that AFAIK. 6.2/6.5 uses a timing chain for cam-crank...

    My options, and your opinions.

    Well that might be the ticket for the 6.9. The description reads right. I don't think there was ever a direct injected 6.9, only the IDI, so I'd say the piston is listed right and they just used a stock image. It's pretty common amongst parts places. We call that dish a mexican hat, and on a DI...
