You don't need to worry about bulletproofing the engine at the moment. Your main concern is it's current health, leaks, fixing the miss, and oil pressure.
Leaks is just a need to know. With this much blowby it will leak. You just want critical ones fixed like oil cooler lines. (And turbo lines.)
It's not in daily driver shape. You seriously need to park it until you know why it's missing. You need to know what the real oil pressure is after an oil change. Absolutely get an oil sample to see if the engine is eating itself alive. Then it's your call if you want to grind up what's left till it quits or bulletproof a replacement. If your lucky you can do some fixes and get a lot of miles out of it.
I do recommend a AAA membership. This gets the truck home so you can work on it.
