It's an interesting thought but the V6s in my jeeps do quite well. Perhaps not as good at the fuel mileage bit but they aren't my DDs. And I don't have to screw with the Jeeps.

I second Daves thoughts. I have no regrets about the Kubota swap. I also used the small denso style alternator...works like a charm. Dave....your work looks great! Another Kubota on the road! Woo hoo! Edited by Lemield - 13 Dec. 2017 at 7:16pm |

I think the V6 is the best gas engine swap in these old Jeeps...I've had them and loved them too. :)

You really can't do it in a Jeep but my neighbor put a Chevy I6 in his Scout. Quite an improvement. We have had to jump out a few times and help push the thing up a steep hill with the old motor.

What was the reason for installing the fuel pump? Just curious!

I didn’t need to and the in-line pump. I thought that I had a gravity feed issue where I wasn’t getting enough flow to the filter I had mounted on the firewall (it was much higher originally)then to the fuel pump. I have the pump on a manual switch and so it might get use when I charge the fuel filter to fill the filter and bleed air out...but it’s not needed.
After a ton of trial and error I figured out that the main issue was just needing to tighten down the hardline from the fuel pump to the #1 injector. I also replaced the “bleeder knob” on the pump as it was missing when I got the engine and I hadn’t noticed until I got some advice from Greg. It apparently super common for people to over tighten these and as they are made of brass, off they come.

I picked up an Artic Top this weekend. It needs some repair but everything is there except most of the glass. Here’s a test fit of just the top.
Anyone have an idea what the triangle shaped hole under the window was for?

That looks like a decent old top Dave. I know nothing about those kind of tops so I can't help answer your questions....you might try posting it on the general part of the forum.

That triangle hole is for checking the air in a spare tire mounted in the stock location, when the spares bolted on backwards!
None of the artic tops I’ve been around have that hole.

A quick google search showed a few of them. None have that triangle hole in them. So, maybe a PO modification??

Thanks everyone. It’s a really clean cut and a distinct shape and so I thought it might have a known purpose. The top sure looks like it was military. Maybe it’s for an antenna on a M38 radio?

Bad news...I blew my engine yesterday. I was going up a long hill in 3rd at about 8 psi and boom...lost power, lots of smoke and blew my rear main seal. There was a lot of crankcase pressure coming out the valve cover vent and so I’m pretty sure I blew a cylinder wall.

Well, crap. I have always heard that those diesels were supposed to run forever. What do I know? I pulled my little motor home in my yard and my neighbor came over and asked me what it had for a motor. I told him that it was a Mitsubishi Fuso. He is a diesel mechanic and he told me that what I had would run forever. Not much you can do now except find another motor to put in. You already did all of the tough work on the Jeep.

I don't know. My neighbor went out to change the oil in his father in laws tractor. It looked like thin tar draining into the pan. Darn thing. Ford 550 (New Holland) It is still putting away out at the farm.

So sorry to hear that Dave! Bummer! Hopefully you can find another Kubota replacement engine.

I'm curious what you were getting for fuel mileage. I do not have diesel envy. My 12.000 lb camper gets 11 MPG no matter if it is summer or winter and it doesn't care what is hooked on the back of it. The only bit of diesel envy I have is that a friends father has a motor home that carries 250 gallons of diesel. You guessed it, the guy used to be a over the road trucker and his old truck carried over 500 gallons of fuel.

per Greg’s advice I’m going to do a compression test before I take anything apart. I had the cylinders bored out +.5 and so that may be involved with the failure. There is also a possibility that excessive EGT was at play. I didn’t have an exhaust system...just the down pipe and so that should have helped keep EGT down...in theory.
