D7 17a question

Ok,
I used the D7 for a little while today and noticed an oil leak. It is where the crank goes in to the pony motor, but I didn't use the pony. Is there oil pressure from the diesel running through the pony all the time? It isn't a real bad leak, just a drip, but it left me scratching my head a bit. We are gonna pull the pony in a few weeks and go to direct electric anyway. I just wondered what was up with this.
I guess the real question to this is, are there also oil passages that we are going to have to seal off when we replace the pony?

Thanks,
Todd

Some pony engines had their own oil supply seperate from main engine.Some got oil from main engine and if youre did then you will need to plug the oil holes.You will need to cap the water outlets too.Think some even used the main air intake.You will see when you remove the pony.

Pretty rare to find a unit with the common lube system as they were a disaster and most got changed back to self contained lube many years ago. Cat provided a kit for the conversion.
