2003 F250 7.3 115,000 miles

Truck overheated and poured oil out the back side of the engine ( don’t know exactly where)
Noticed a few weeks prior to this that my coolant was slowly going down and didn’t see any leaks, added about a gallon and it would pressure up and leak a little out of the cap as well.

drained some of the oil and a good amount of coolant came out. Pressurized the coolant system and lost 1psi in a couple of hours.

I replaced the injector cups about 3 months ago after I got diesel in my coolant, was wondering if this could be related to this issue as well.

Troubled on where I should start. I don’t know how long coolant has been getting into my oil, and how bad it has destroyed my bearings. Don’t know if I should start with pulling oil cooler or water pump to check front cover.

The truck has a bank power kit on it and has had it since 30,000 miles. Bought the truck with 98,000 miles and took the bank chip out and put a hyrda in.
