I got it to start , and lots of people asked for a pic of it. There was a serious knocking sound coming from, what seemed to be the front of the motor, after it did start. Also there was alot of white smoke. any suggestions? I didn't drain the fuel from the tank (because I didn't expect it to start) I will try to drain it and put some fresh fuel in it.

Knock can come from bad injectors too..
The noise seeming to come from the front might indicate the vacuum pump or the crank pulley.

The crank pulley fits over two dowel pins and can sometimes hang up during instal and feel like it's all the way home.

White smoke is incomplete combustion diesel gases which should clear as the motor warms if all else is okay. Loud knock along with white smoke does point to bad fueling.

That can be your knock right there. Gas + diesel engine= no fun

W/ the 617s I think you can get away w/ up to 10% rug.
I am first in line to buy that contraption once all the bugs get worked out and the new novelty has worn off.

Drain the fuel and put some fresh diesel in there. That gasoline is hard on diesels.

Congratulations.

You also can run it from a gas can under the hood for testing.

Any links or more info on converting a wrangler? Im wondering what years, extra parts, etc to do it. That temps me to sell my Cummins and convert a nice Wrangler:-)

Thanks!
Zack

Thanks for all the info, I believe the PO of this jeep ran it for a while. I think the fuel in the tank is just old and there might be some water in it. I don't think there is any RUG in the tank. I might just run it off a container of fuel from the engine compartment. I was not sure if there was a pump on the motor or at the tank. I'll try it and see what happens.

As for a link to converting a Wrangler to this configuration.... I looked and could not find any. I bought this jeep with the motor already in it (they just did a bad job of mounting it in the frame). The adapter to the tranny looked good tho and most of the lines seemed to be there. The only problem is the oil pan is directly over the front differential. I plan to lift the jeep to corret this issue.

That little issue sways most ppl from converting with these engines.

I guess you can get your parts from the local Jeep/Chrysler dealer?

With the spring over lift it will put about 5 in between the motor and diff. If I put a lift spring on it will lift it even more. I might even do a shakle reversal. I saw a cherokee with the same motor installed it was a 2 wheel drive though. I believe where there is a will there is a way...

Can anyone tell me how much fuel the 617 motor should use? I used a 1 liter container and it only lasted a minute or two. Could this be contributing to the white smoke? Maybe something needs to be adjusted. Any thoughts would be great.

On a positve note the jeep moved under its own power (the tranny worked)

I can't say for sure how long a 617 will run on 1 Liter, but it should be a lot longer than 1-2 minutes, at least 15-20 min or more. Somehow you seem to have a major overfueling condition, is your IP rack damper or full load screw cranked all the way?

By the way, I have also been researching this conversion for my CJ and would be curious to know some info reagrding transmission used, adapter plate, and if the 4x4 transfer case is still connected. Any info you know and are willing to share would be greatly appreciated.

I am not sure what or where to adjust the IP or any of that stuff. I just thought it would get better run time on that fuel. As for the conversion. The parts were all there: adapter plate (it looks like they just welded a solid 3/8 in thick piece of aluminum on and drilled some holes for it to mount to the stock Jeep 3 spd auto tranny). I had to make the motor mounts, I used some hydraulic filled mounts and made the bracket to the frame and to the motor. The Jeep radiator is used and the tranny cooler. It is set up for a/c but I will worry about that after it is on the road as a DD.

The tranfer case is still connected or I would be less interested in finishing it, LOL.

I will be interested in putting an intercooler in it after it is on the road also.

Did you connect the return line to the container too?
If not, then the fuel all just made its way to the regular tank and avoided your container completely. These engines circulate about 15x the amount of fuel they actually use, hence the feed and return lines on a diesel.

Return line? of course I.... Didn't.... I didn't know about the rate of return kinda like investment property ehh.

so much for me thinking something needs to be adjusted really badly.

I'll have to try that next time maybe it will not smoke as bad or even quieter and smoother.
