So the dakota was well mantained truck. valvoline dura blend 10w30 vwb 5/10w-30, every 3,000...
So I bought it to pull my trailers and winter 4x4, maybe have put 750-1000miles on it.
two three 100+mile trips with 14' tandem with idle time ran great.
one 3.5mile trip unloaded trailer lifters collapsed and lost all pressure. loaded trailer started with low oil pressure on gauge drove slow home with lifter noise.
sat a week and started with good oil pressure and lifters pumped up. let it idle 2.5hrs good pressure drove 15miles with good pressure to mechanic.
he changed the oil and pressure switch, said he drove it hard loaded a trailer heavy and drove hard and had good pressure, he was stumped.
100+miles towing boat after that and alot of idle no problem.
last trip half hour idle to temp drove 4miles 55mph pulled into my friends and lost all pressure. let it set five minutes started with some pressure but wouldnt pump the lifters up. shut it down 10-15minutes started up with good pressure 1.5-2minutes quiet as a church mouse. let it idle about 2hrs and drove 4miles home good pressure.
i am stumped!!!
