6.0 L gas
4x4
This truck runs, but it has a couple issues.
The engine oil has trouble maintaining pressure. One mechanic suggested it might be pushing oil past the seals. A different mechanic suggested it might be an issue with the oil pick-up tube.
I also recently noticed the power steering is leaking. It’s a slow leak and I can’t pinpoint it.
There is also a leaky rear axle seal but I’m getting that fixed this week.
I will include some seat covers to cover the exposed foam on the driver’s seat.
The air bag sensor in the front has failed, and I have a new one ordered.
