rear main seal

You don't want to know.
The 617 has a "rope" seal for the rear main.
The main oil pan needs to come off to replace it.
Every diesel I have owned leaks there, and I just let it drip.
Not familiar with the diesel in the G, but my best guess would say it's the same.

Thanks,

This is what I figured. Actually, I have an engine out of a 83 300TD in there with just a few mods. The Gs never came with a turbo. I would be willing to just let it drip, I have for a year now. However, it is getting worse and when I drive on the highway, I get small drops of oil covering the rear of the vehicle and the entire undercarrage is alse covered. This is both a pain because i have to wash it so regularly and because I just dop't think it is very good for all of the other components under the vehicle, especially the rubber ones. Also, when travelling off-road, water can probably get into the engine (if oil gets out) and dirt and debris stick onto all of the oil reserved under the vehicle. This is only speeding up the rusting process because everything is collecting.

After taking off the oil pan, is it just a matter of putting in a new seal. I am going to have the engine out soon to re-build my tranny and I am thinking this may be an optimal time to replace the seal as well. Any other thoughts?

Thanks,
Steve
