Oil pressure was never low, always above 25 hot low idle but never over 50 hot or cold.

How much would those bearings take a beating from lugging? If they do take a good amount I'm willing to bet that's a lot of the issue since this truck was not speced to pull the weight that I do.

Changed the fuel filters as well even tho the Davco wasn't even half full but the filter was black.

Going to order a new air filter housing. It's slightly warped but I think the biggest issue is one of the bolts broke the plastic that holds the two pieces together. It has some dust on the inside just past the filter.

Dust getting past the air filter is a quick way to wear out the cylinders. Needs to be fixed asap.

As far as lugging it at high torque and below 1500rpm a lot ... it cuts engine life about in half or less over time.

Going to order the new housing Monday. This thing has been lugged all its life until I got it but there is only so much I can do until I can change the rears.

Surprisingly it doesn't seem to be using any oil.
