International 684 Fuel in Crankcase

[mnkyfst]

I purchased a 684 last year and all was well until a week ago when I checked the oil and noticed it was high. I check it prior to when I use it and this was the first time I noticed it. There was a strong smell of diesel as well. From what I've found, it looks like chances are that it's from a seal in the fuel pump. I have 3 questions: 1. Is there a place to check for a leak that is easy to get to where I can use UV dye near the pump? 2. Is there a seal that goes out on these that is common that will cause this problem? 3. Would it need a professional rebuild, or is this something that can be replaced by removing the pump?

Usually the pump front seal, and it's wise to have all gaskets/seals replaced when one leak starts. Pump could also need new front shaft bushings replaced and reamed if
worn badly to keep the shaft centered again.

Thank you! I am in Louisville, KY. I saw you're in Indiana. Do you know of a trustworthy place or person that can do the work?

Some of the members here have sent pumps to dieseltech to have them fixed in the past so why not send it to him.
