Isx cm871 rear structure and front oil leaks

[jesse24spd]

As stated this was all done and added by previous owners. I’m on the forum to learn the right way for these engines. I’m coming out of a vnl 780 d13. Looking forward to putting the isx back to what it should be for reliability.

I have yet to have a chance to hook up with laptop to see what tuning is on the truck. Not sure if it pp tuning or someone else’s. Planned to remove the extra oil crap when taking care of said leaks.

Will it be ok with the fass pump for the time being?

Truck has a 132” Ari sleeper on it. Me and the wife are on the road about 300 days out of the year so the added amenities were a factor in the purchase, but we did get it quite on the cheap side.
