I've either been lucky or good.....My 2007 Ram 1500 has 394,500 miles on it and it is still running.
It has thrown some codes lately. Cylinder 5 misfire, cylinder 6 misfire....Plus I'm smelling the sweet smell of coolant in the exhaust. Sometimes it has steam in the exhaust in warm weather. It is time to make some changes.
In 2009 with about 59,000 miles, 2 of the MDS lifters on the right bank conked out. They had to pull the head to hone 2 cylinders that had carbon buildup. I'm wondering of they actually pulled both heads and staked the intake seats because I haven't heard of anyone else with this many miles on a 5.7 engine. I've never overheated it so maybe if the valve seats weren't staked, I avoided the dreaded "dropped seat" issue just by being responsible.
I don't like the new trucks. I don't like the styling, the busy interiors, the lack of a CD player, the knob for a shifter....or the exorbitant prices for even a 3 year old low mile used one.
I'm keeping THIS one.
