Jackelope, have you seen any 4.7s with oil pump or sludge issues? After knowing two people who dealt with that, I looked online and it seems to be a weakness for that motor.
The reason there are so many Ruger upgrades is because they're necessary.

After knowing two people who dealt with that, I looked online and it seems to be a weakness for that motor.My Ram 4.7 started getting oil starved at the valves exactike FC described.I was meticulous about oil changes, at 230k burning up valves gets expensive, lolBoth motors will sludge up badly if they aren't maintained. I put an oil pump and a set of main bearings in a 3.7l at about 50k due to the oil only being changed about 2-3x at that mileage. The older 4.7l was well known for the same problem, both build up sludge around all of the valley drains and the ones in the heads as well. The result is first an oil starved valvetrain that gets pretty noisy, later they develop oil pump and bearing problems due to the oil draining so slowly back to the sump that the pump is starved.
