Isuzu Diesel Engine

Hey guys,
I know this isn't the best website for this question but there are a ton of knowledgable people on here that give quick responses. I was wondering if you all could give me some knowledge on the Isuzu 4LE1 motor. It's the 4 cylinder 2.2L diesel and I have the opportunity to buy one for cheap from an 87 Isuzu pickup with 170k miles. I have no clue what I would do with it but I'm intrigued by diesels even though I don't know much about them and it would be cool to have one for a future project.
Is the 4LE1 a reliable engine?
Is there/ where could I find aftermarket support for it?
Is it simple to work on?
Has anyone swapped this into a Ranger?
Thanks!

EDIT: the engine I'm talking about may also be called the c223. It's a 1987 so I'd appreciate if someone knew which one.
