The 22R is definitely a workhorse.
I wouldn't be too concerned about the oil consumption unless you are going through more than a quart per tank.
I have had many VWs that went through more oil than gas, and they always ran like tops even if they fouled plugs like mad and left their mark in all my friends driveways.
Given that the old girl is only meant to run 50-60mph down the road, driving her at 65-75mph is going to make blow-by much worse. There is a lot of weight on that chassis for that engine, so 120k on the ticker could be about all she will get. However, she might run for a LONG, LONG time the way she is.
Yeah, it's a real tank. The only thing I've found the deeper I go into the engine is just how neglected it's been, but it still runs fine.
As the old saying goes, if she ain't broke, fix her until she is!!
Simple things to check -
Smoke out the exhaust when warm. If there is no catalytic converter, there will be some gray/black smoke out the pipe. No biggie. Blue/grey fog out of the pipe is going to be any of the fore-mentioned (rings or valves)
Just a little white puff.
Oil on the ground - Probably leaking valve cover gasket. A leaky valve cover gasket can be a sign of plugged oil return passages. A good block cleaner when doing an oil change is decent at cleaning these out.
Haha yeah... I found the source of the leak. It's the radiator. There's oil in the coolant, but no coolant in the oil. The exhaust doesn't smell like antifreeze. Slightly frightening, because my understanding is this: when the head gasket is blown, oil and coolant can exchange freely because they have no significant pressure difference. If the head cracks, pressurized oil (50psi) can find it's way into a coolant line, but the coolant can't mix with the oil due to the pressure.
However, I have also read that unless it's blown really bad, on a 22R in particular, coolant won't mix with the oil. I don't really know what to believe.
Smoke out of the oil cap when running is excessive blow-by and is a sign of worn compression rings. Get a compression test done, or learn how to do one yourself. Make sure to adjust the valves, if possible. I can't remember if the 22R had valve adjusters or not. The overhead cam engines with spacers on top of the valves are a PITA to deal with so I never massed with them.
I swapped the PCV valve and the amount of smoke coming out of the cap went down by a
lot. There's still a small, visible amount of smoke coming out though. Also, literally all of the rubber hoses are ancient and cracked, and need to be replaced. I'm so surprised that this thing runs at all.
I guess you could start with replacing the valve cover gaskets, distributor o-ring (not really a source of leaking, but if you are paranoid), oil pan gasket, etc. This will stop external leaks.
I would definitely get the compression test done to make sure that the cylinders are all somewhat balanced and that you don't have valve problems.
The crooked fucker I went to said the valvetrain is bad and that's where the whistling sound at midrange rpm is coming from. I'm guessing they just need to be adjusted, the guy tried to tell me he knew the valves were busted by taking off the air filter. Valve cover wasn't touched, I know because I asked him, and because those bolts are stripped.
In this day and age, unless you find a mechanic that has been working on cars since the 80's, you are going to have a hard time finding anyone competent with these older engines. That's why I have switched to diesel power. Not much has changed there, and I can put a Kubota engine in my car, if necessary.

That's a really good point. When I need to replace the engine I might look for the diesel 22R. It exists but I don't know how common it is.
Thank you for sharing your advice and knowledge, I appreciate you
Death Wobble -
Small truck chassis, large box on the ass == PITA to drive at highway speeds.
That said, check your ball joints and tie rod ends
first.
Second, check the steering gear. That truck may have a rack and pinion, but I can't remember. If the steering wheel goes back and forth more than 1/8 of a turn without moving the wheels, you need to figure out what's up.
Third, because I can't remember what front end that truck has...check the control arm bushings and and stabilizer bushings. Unless she was in an accident, those should be fine.
If everything is tight, put a heavy duty sway bar on the rear axle. That will help, but not eliminate the death wobble. Something like this:
www.summitracing.com/parts/hel-7539 (Hellwig #7539). If you can find one, put a bigger sway bar on the front, 1" diameter or bigger.
Old trucks are cool as hell, but anything over 45mph makes them a friggin' death trap.
Yeah, I couldn't exceed ~50mph without it wobbling. I was driving another large vehicle the other day and noticed it did the same thing when being passed by semis, which makes me a lot less worried about it. No accident damage so far as I can tell, everything on the frame is straight and in order. Bumper has a few dents but the fenders are definitely original and have never been impacted. Fiberglass has never been patched. So I'm operating under the assumption that it has never been in a significant accident.
The steering wheel has about 1/4 a rotation of freeplay. It also has no power steering. I can rock the steering wheel back and forth (from one side to the other about 3/4 a rotation) without the wheels being affected at all.
I didn't know sway bars exist. That's pretty cool.
I appreciate you, thank you for all of your advice.
