I Found A Surprising Secret During My Jeep 4.0 Rebuild - Must Investigate Later!

Seems like rebuilding Jeep 4.0s has become just causal to me, But it seems like a certain year model is just known for being less reliable than others. Never really found out why, but I think I stumbled across a big issue worth investigating later on. Otherwise a video of me doing my regular 4.0 rebuild/refresh to resale. Hope you enjoy and can't wait to dig deeper on this idea!!
