2010 Po-Po 5.7. Just over 100K on her. Just changed the plugs(Champion), `11 IAT, Royal P in the differential, Mobil1 synthetic, coolant tested and appears new. My last truck was a 4.7 Durango and there were little things like cleaning the IAC that would help performance. Was thinking bout dropping the tranny pan and changing the filter and installing a drain plug and doing the drive n drain for a few cycles. I have the "dipstick" but no way of measuring the fluid temp. Ran some Mopar CCC through the intake, not much smoke so I assume there wasn't much carbon built up. PCV rattled but was really oily. Thanks for the tips!
