I'm considering buying a 1989 BJ74 and I need to know what to look for. I know these are durable diesels and yes I know a 1HZ would be a better engine but it's all about affordability. But, are there tell tale signs of things to look for? I will include some pics of what I was mulling over. What issues should I look for on a diesel at 161,000 miles? Any known rust spots? I;m probably going to spend around $15,000 if this doesn't sound like too much.
