I'm gonna go and look at it today. Even with only 2640 hours on it, I'm not sure if it's worth bothering if it's a Dot 1 engine. I hate oil leaks.

I know the Dot 4's are supposed to be practically indestructible. Other than the oil leaks, how did the Dot 1's hold up? 

Just wondering as I know where a Dot 4 is sitting that came out of a combine. I have a 1850 with a stuck motor. Might take the one out of the 2-105, swap manifolds and pumps and drop it in the 1850 and drop the Dot4 in the 2-105.
