That's a good find! These cars are great to learn how to wrench on, solidly reliable and easy to work on. Welcome to the forum, I started with my old '83 when I was 16 and learned a ton.
The first thing I would do is pull the valve cover and check on the exhaust side timing chain guide, it's about the only weakness in the 22RE. When the timing chain stretches, it will overwhelm the tensioner and then break the plastic guide on the exhaust side. This will then let the chain rub against the front cover, right behind the water pump. Enough rubbing and it will dump coolant into the oil pan and ruin the engine.
