4.7l woes and rant

I've had luck with my 4.7s. first one, bought the ram new, sold it at 140k. later on bought a Dakota with 140k sold it with 220k. i picked up a spare, running, 4.7 just in case the Dakotas failed.

I hear these motor dont tolerate over heating very well. Valve seats fall out. Also, oil pressure switch fails leading people to believe its a catastrophic oil pressure issue.
