    Stolen IDI

    Sad news - some low life types swiped my truck last month while I was out at sea. Not good, but hopefully it shows up. I'd appreciate it if you guys could keep your eyes open for the truck or any parts that might show up. I'm going to be completely out of contact for the next 2 months or so and...

    (2) Brownie OD boxes - $150 ea - northwest WA

    Not mine, found this add and I know there's folks off an on wanting to use a brownie box od. I'd grab them to resell down the road but I'm leaving on deployment and can't. Hope someone can use them. https://seattle.craigslist.org/see/hvo/5904501936.html

    Return line rail

    WTF seems a bit strong to me. If that want to spend your beer money on fancy bits that may or may not work than it's not skin off my back, and I'm not trying to insult on demean either Justin or anyone who buys the rails. That being said, it seems like a poor investment to me. May not be a huge...

    Return line rail

    I suspect most of the horror stories are from folks either dealing with 30 year old parts, trying to reuse old stuff instead of new or screwing it up/damaging things doing other work. It's a fairly robust system IMHO as long as it's treated with some respect. I suspect putting the rails on...

    Return line rail

    Depends on what's leaking - if it's rubber line getting hard or the caps themselves, then yes, but I think most leaks are the o-rings which would be just as likely. It also sounds like maybe you have bad luck with them? I've ever had an issue in ~15 years of driving an idi. Admittedly that with...

    Return line rail

    You'd have the modify the injectors them selves. Not an easy task. Keep in mind too how big of a problem it really is.... yes, the o-ring can cause problems on a 20-30 year old truck.... we tend to forget that that also means they lasted 20-30 years, and if done right a new set will last...

    Return line rail

    Out of curiosity, what do you consider a reasonable price? Might be an interesting machining project to try. Wouldn't be billet though, I'd probably either do steel or brass and have the hose nipples be separate pieces brazed or soldered onto the main body.

    Return line rail

    Agree with discussion of issues with tolerances. Not only does the horizontal spacing between injectors have to be exact, but lateral position, angle and height also all have to match. I would expect there is some degree of variation between injectors and between engines/head casting, especially...

    ZF5 oil cooler and filter idea

    First question is do you honestly need it? Sure, it sounds nice, but the units seem to live long health lives without needing any cooling or filtration. Filtration would be nice, but what is it really going to do? You shouldn't really have any wear products (unlike an auto where the clutches...

    I don't understand the physics

    A return line leak should not cause rough running except for starting. The return line leaking air allows the fuel retained in the system to drain back (same idea as an air leak in a siphon making it not work). When you start it then there is a certain amount of air that has to be purged from...

    time to replace my 16.5 wheels

    Negative unless you know something I don't. I just went through this about 6 months ago. No one I called or talked to had any. The listings are still there, but there's no inventory anywhere. What I was told is BFG was the only company and stopped in 2014 or so. I had the exact quandary as...

    High Idle Solenoid Idea

    Using the cruise control system would be more work than it's worth. All but the 93/94 system runs on vacuum anyway, so that's not going to help any starting. The electronic system on the 93+ could theoretically be used, but it would take some significant electrical engineering and fab skill to...

    Intercooler w/ wide radiator

    Use a air to water setup. More bits, but easier to route. I would want an intercooler for anything over about 10 psi. Just because the egts aren't high doesn't mean it's not sub optimal.

    1968 f250 2wd 360 to 4x4 6.9 swap

    HX35 is a good match. IMHO anything bigger is pointless. Mine has the stock wg setting and will make a solid 19-20 lb. That's enough to match well with the bull moose pump and makes good power. I also have studs, decked pistons and ceramic coating. I would be hesitant to run the HX35 on a stock...

    High Idle Solenoid Idea

    Nothing stock, but I'm sure you could cobble up something strong enough. Look at some of the surplus sites for solenoids. That being said from what understand of the injection pump setup throttle lever position has no bearing on starting - below idle speed the fuel flow is governor...

    do you take your IDI on long trips?

    Took mine across the country and back and has been my daily driver for much of the past 6 months. Something like 15,000 miles in 6 months. Brought a Dodge parts truck and a 10 ton trailer back from CT to CA too - 23,200 lb gross.

    1356 Helicoil

    Understand that, my concern was if the casting is thick enough to handle the hole being drilled out for the insert - if it's thin there to begin with then there might not be enough material to have sufficient strength after the hole is drilled out. Wouldn't worry about it as much in cast iron...

    4wd DNE2 Project

    Another update.... good and bad. Good news is I've run 6 months and something like 15k miles on this setup including going across the country light and coming back pulling a gooseneck trailer and a parts truck at 23k gross. No issues and the dual range was a lifesaver with that much weight...

    1356 Helicoil

    Got a 1356 tcase with 5 of the 6 mounting bolt threads stripped - is there enough meat on the case to heli coil them or do I need to find a new case front?

    How much air do you reckon goes UNDER our trucks? RE: inter-cooler radiator

    I didn't have a problem fitting a water/air IC on mine without any major changes other than deleting the vacuum pump (electric/hydroboost)... I have a 1" thick 24x12 (IIRC) water cooler between the radiator & AC condenser and the actual IC mounted inboard of the pass battery above the frame...

    4wd DNE2 Project

    I suspect much of it is. The gears, shafts and case are obviously custom but most of the rest is almost certainly standard off the shelf parts. Think about, why would they custom make stuff when you could just get common ones? Bearings are standard with the exception of the DNE2 countershaft...

    4wd DNE2 Project

    I'm running synthetic 80w90 or 75w90. No noise issues. Noise probably means there's a problem and you're just masking it with thicker oil. I would guess the thrust bearing is going bad since that seems like the weak point. I personally would pull it apart and check all the bearings - easy to...

    Trying to understand idi air flow

    Direct injection is inherently more efficient, as is higher pressure injection. The computer control also allows finer control to get the proper amount of fuel at the right time for the optimal burn. Net air flow is displacement times boost - 6.0 @15 psi of boost is essentially the same as...
