So the white one I got had been sitting for a while.
I've seen a few tips.
I started working towards some mentioned from Pete Cruiser and a few other guys. (Silently watching 👀)
I think It has a burnt valve? Maybe carbon build up?
I have a 4.0l HO with transmission, transfer case, wiring harness, and computer with 50k on it.
Is that a hard swap?
