That's all pretty normal stuff you replaced so far. That fuel pump lobe I mentioned the other day was actually a first for me. I have never had it happen before. My other truck seems to need a fuel pump every couple years, they just don't make them like they used to and I usually buy the cheap ones. It's still lifetme warranty and I have gotten a couple replaced on warranty.

I really dislike oil leaks and I don't like messing with the oil pan in the vehicle but if you are going to do it, a 4x4 is easier than any other vehicle. I need to change a rear main on mine next week so I'll just have to suck it up and get under there and do it. If I had to do the front one too I would seriously think about pulling the engine but most likely I would suck it up again and take the balancer off and just do it. My engine is clean, the job is 3 times worse if you are working with 40 year old grease and dirt.

Pulling the engine is a good excuse to pressure wash it and put new bearings and oil pump and timing chain and cam and lifters for a quick freshen up. If you get deeper than that then a crate engine starts sounding pretty good. I would try to document how much oil you are actually losing. My bad rear main can pump out a quart in 100 miles. If your oil isn't disappearing too fast then maybe you can live with a few drips here and there.
