I'm sorry you've been having so much trouble with the '84. My '85 4Runner's been great. I've been driving it for almost 12 years and it's never been in the shop--partially because I'm scared of what they'll find.
Dad and I replaced the engine internals when I got it--it was consuming some oil. I did leave it on the shoulder one time about 5 years ago when the oil pump seal started leaking on the highway and I didn't want to make a mess and keep driving. I put that seal in myself though, so I sure can't blame the truck.
It wasn't a big hit on the wallet...I came back with a U-haul dolly and the neighbor's pickup, and once I got it home, it was easier to find the leak and put in a new seal for just a few bucks. In the beginning, I was having a little fun with modifications but for the last 6-7 years, the only expenses have been gas, insurance, oil and filters, and the hefty $10/year tax. :coffeedrink: I'd drive it anywhere...if there's gas in it, it will get you there!
I've heard some say that the carb'ed 22R is the most reliable, but I think the EFI 22R-E is the most hands-off. It may not be as customizable, but it just does its thing and keeps on running without having to mess with it.
