4.0 rebuild

[90ranger90]

Hey everyone, I have a 1990 4.0 4x4 and the transmission just went out. My engine is leaking oil from various places also. I'm on the fence between selling or keeping. Im thinking of taking the engine out and rebuilding it myself (partly for fun).
So i have a few questions.

Is is worth it to get a rebuild kit somewhere, or is it a complete pain in the neck and i should avoid it at all costs

Any advice from those who have rebuilt them?

Thanks!

If it were me it would depend on the compression numbers.
If they are good, I’d just reseal it.
