IT'S ALIVE!!!
Besides the fact that its been way too long, I have this new 4.0 fully installed and it sounds amazing! Just finished buttoning things up today, added the fluids, turned the key and BAM...nothing. My battery was totally dead, lol. (I left the key in the ignition). So after jump starting it, I turned the key again and it started right up, no check engine light, no codes, and everything looks and sounds perfect really. Broke it in and took it for a short drive around town and up the nearby mountain. The feeling was absolutely amazing to be driving this again. I'm so stoked right now to have taken on this project and been able to do a job like this which I never have done anything remotely close to this before. Shout out to my brother for helping me out and seeing this thing through till the end.
Everything that was done and/or replaced was:
4.0L Engine, PCV Valves/grommets/hoses, Oil Cap, A/C Condenser, Radiator, Water Pump, Fan Clutch, Coolant Reservoir, Thermostat and Housing, Belt, Spark Plugs, CPS, Oil Pressure Sending Unit, Air Filter, Oil and Filter, ATF (that leaked out in my garage from sitting so long), Coolant drain, flush, refill.
I removed the KC Flex lights temporarily, as i'll be running a new light config here shortly. Also few new add-ons in the near future are on their way too.
