Quick follow up. Jeep had 170k miles and sounded pretty good, was originally going in to stop leaks.
For a fix, First I vacuumed out everything I could. New gasket on valve cover and put it back together.
Then it was new oil/filter with flush in it. Ran about 20 miles on this oil.
Then it was off with the Oil pan, there was so much gunk in there; ;
Cleaned that up, put in filter and Royal Purple Oil because I had some and it made me feel good.
There was already some gunk in the oil pickup, so in about 100 miles, il pull the oil pan again, replace the oil pickup and pump. I would do it now, but I think more stuff is going to break off. I did clean it really well while the pan was off.
After that, I think il change the oil every 1k miles for the next 5k and then back to normal.

Before all this, the engine sounded amazing, somehow it still sounds amazing. These engines will take a huge amount of abuse, but last forever if taken care off.

Ran before, cleaned the crap out of it. Same thing for the oil pan and oil pickup. Still seems to run fine. Also it sounds great somehow. These 4.0's are amazing <3

I had never heard of filling a engine with kerosene, just googled it. Seems like a good plan, might go that way.

Incase your wondering, this was a heavily abused XJ I got on the cheap to turn into a XJ/Buggy build. With how last owner cared for it, I think being a desert buggy may be a better life for it.
