    I've had more time to devote to the motor today. With most of the fuel trim completed, it was time to move over to the passanger side of the engine.

    Installed camshaft oil lines. There are two special aluminum washers on each connection which acts as a 'joint'. This joint creates an oil seal. Someone in the past had WAY over tightened and distorted the washers which I had to replace. It was hard finding them but I found them at a diesel shop (free :)). I had the same trouble with the fuel leak off joints ot top of the injectors. I also installed the fuel lift pump and made the connection to the secondary fuel filter.

    This may be a better picture;

    Also installed the intake manifold. The igniter (glow plug) is directly under the intake to the left.

    There's not much left to do on the engine. I still need to fit the starter and oil boss and cartrige filter. I'm still undecided about using the generator or the alternator :?

    Will it have Lucas electrics or more common stuff?

    evidently the M/F tractor line did on some models. Obviously wouldn't apply here though.

    That makes two I know of, the other one had some DOT stenciling on the hardtop. It is about 20 miles from me last I saw it.

    hey peter. it's good to see your attention to detail on the little engine. that's what always set's the diesel mechanic apart from the rest. the engine uses a lucas starter. lucas is from the uk, same as the engine so that is a natural choice. something about the "glow plug". mf , ford & some perkins gen sets used them. the way they work is you hold the key to a certain position for a min or so & then crank it. as the "plug" heats up a valve opens & lets some fuel into the intake. when it makes contact with the "plug" which should be still hot, the fuel actually ignites & burns a flame in the manifold & gets sucked into the cyl to help with starting the engine. these things were problematic in real life. the valve wouldn't open or the "plug" would ground & short, or the valve would stick open & flood the engine when it was off & create a hyd lock when it was started the next time. diesel fuel siphons. you might think about a block heater instead of the igniter assy. a canadian company named katz makes them & they have then for frost plug holes & also for the water pump suction hoses. you just plug it in for about 20 min or so before you want to crank it & zoom, already warmed up. i have them on all my diesel trucks & eqpt, they work great. keep up the good work but hurry, old man winter is on the way!

    Hi Andy and all;

    Andy (above) was kind enough to part with his Perkins 4.192 which now sits in my barn being fussed over.

    I'd be interested in hearing others experience with 'Katz" system, particularly north of the Mason/Dixon. Thanks for sharing.

    There is a small resevoir mounted above the engine on the firewall which (I believe) gravity flows down to the glow plug. That flex line goes to a steel fuel line. The other two connections on the right of the resevoir go to the injector leak offs and back to the fuel tank (return). So it would seem that the fuel source for the ignitor (glow plug) can only come from the leak offs. I'd say it holds about 3-4 ounces. Of cousre, it would keep pumping as the engine ran or was cranked. Maybe that's why the resevoir is so small (so it wouldn't hydro lock if it failed). I really don't know what turns it on or shuts it off.

    See pic below;

    Wow, I'd love to have a look at it. My motor mounts do not appear to be stock and I am wanting some photos to compare. Can you point me in the right direction?

    hmmm....that reservoir is a new one on me. tractors & gen sets used residual return line pressure generated by a low pressure check valve in the return line to force fuel past the glow plug when it got hot & the valve opened. how come whether it's jeeps, army trucks, '57 chevys or what you can never find the people who built these things?

    It's all very new to me...

    I forgot to mention that there is another low pressure line which comes from the secondary fuel filter which connects to the last leak off. Another line comes from the leak off to that resevior. Perhaps that check valve is in the top of the fuel filter, but I haven't taken apart that resevoir to peek inside because it seems to be sealed. That valve may be in the resevoir, but I can't imagine what would actuate it.

    Here's some pics. The first is a closeup on the resevoir. The fitting on the top right goes back to the fuel tank. The one on the bottom connects to the glow plug.

    Here is the completed fuel trim. Note the black low pressure line which comes from the fuel filter up to the last leak off. The feed line which comes from top of the leak off connects to the bottom right of the resevoir.

    And a wider shot;

    When you look up the word "Understatement" in the dicitionary, this is the definition next to it.

    I have never even seen one of these mythical diesels, and you managed to find 2 of them! (even if one did come with some extra crankcase ventilation) So jealous!

    Really nice work on those fuel lines. Can't wait to see more progress on your build. Keep up the great work!

    That is really awesome. I'd like to see more pics of the build, but seems like the dates are really old.

    OK guys, thanks for your patience. The bottom line is that I bought a small farm in November 2011 and also recently married. The project came along with me and it's not dead!

    Part of what's been getting in the way is my seasonal business (I'm self employed) and also that I didn't really have a shop set up. I installed a wood stove in the shop and am in the process of insulating that building. It gets very cold in NH in the winter.

    I anticipate that the jeep will be in the shop within two weeks, but first the body must come off which you all know is a straight foreword process.

    There is a long list of projects going on here, including finishing up our smoke house. Bacon and country ham takes priority. :stout:

    Glad you still have the jeep. If you ever need any help with it just let me know. I am right up the road from you in Hillsboro.
