I have the same motor in my Jeep Scrambler (named Mayahual). The OM602 DE2.9LA was never imported into the USA except in the first Marine Corp "fast attack" G-wagons. When I fitted it in my Jeep, the hardest part (by far)was getting the electronic control for the VE pump to work correctly. I got it though... Then a year and a half later while exploring in DEEP Baja, I dropped into an arroyo a little hard & my throttle potentiometer quit communicating with the computer. Luckily, I just had to shut off the motor and turn it back on again. After that the "no throttle syndrome" happened at the weirdest times, on the freeway doing 70 mph, stopped at a stoplight. No rhyme or reason.
I lived with this problem for a couple of years, then last January I built a hybrid 100% mechanical pump for the motor with the help of a top-notch Bosch pump house.
Now the motor has about 30% more power and is 100% problem free. PURE JOY!!! I will eventually be building a hybrid turbo for it and expect to probably double my horsepower.

If you live by the old cash ranch you must be on my old road, unless they paved that award winning washboard you are definitely driving the right vehicle, some of my craziest driving experiences have been trying to get in or out across that awful road, sometimes only passible in a G wagen... or a 4x4 Kubota tractor.
Is there anything particular you would like to learn about your Gs construction? The frame extension and camper box construction process are still fresh in my memory banks thanks to the large impression this G project had on my 16 year old brain. I think watching its slow buildup at Europa played a huge part in inspiring me to go into metal fabrication, industrial design and ultimately Gwagen re-power/outfitting.
The Mogollon track sounds killer, my family bought 1200 acres and built ourselves an airstrip north of Zuni salt lake (High Lonesome airport), what a staggeringly beautiful and harsh place, the perfect environment for your Gelandebego! Watch out for 'mud heads' and mountain lions.:snorkel:
Mark is the guy, so glad his business took off. Nice to hear Anthony is still at it too.
It's a tiny world, isn't it?
I think I still know the combo to your first gate (Forest let me hike on his pueblo)!
For all my research (and I did a butt-load of it) I am the first person to do it.
This is very important because unlike linear injection pumps that are lubricated by motor oil, the VE pumps are lub'd by the diesel flowing through it.
I mounted a Standyne filter/ trap with a purge pump on the left fender so that if I had to change the filters I could easily purge the air from the lines. If you haven't experienced purging the diesel fuel system, you should do it ASAP. It is the kind of PITA you don't want to learn in the bush. You might also might want to swap the fuel filter/ bracket to one of the older styles that have banjo fittings rather than the stock ones with the plastic fittings/ bracket. easier to bleed.
Yes, no, sort of... It is A LOT more complicated than that! I had to machine some of the parts from the electronic pump to fit into a mechanical body. then there is getting the timing correct. The whole process was not easy.
You have to remember that this was the first electroniclly controlled TDI motor that Mercedes developed for small vehicles. The logic is EXTREMELY complicated! If you want to get a good "head spin" read the section about these pumps and controls in the Bosch book "Diesel Engine management".
If you haven't gathered by now... I'm sort a kook about this stuff (Some think I'm a "diesel snob").
