I'm considering buying a Dodge D50 (mitsu mighty max) with the Mitsu 4D55T motor. I know this truck in general can last forever with some moderate care, but I still have some reservations about this engine.

I am graciously seeking some informed input about this engine's over-all reliability and durability. How is it as a daily driver? How does it cope with converting to veggie oil? Are there any, and if so what, common problems that make these infamous (such as the Toyota Supra 7mgte being known for blowing head gaskets)? Is the block and head exactly the same as the petrol version or is it more heavy duty?

I've searched around on here and mostly looks like the worst is people not finding parts easily. Which I'm concerned with since this is a very uncommon motor in the USA. It's not like a stroll to the local pick-yer-part will likely give me what I need.

There's not many small diesels to choose from over here. I didn't even know about this one til a few days ago. I want something that's cheap for a daily driver that I can run on waste veggie oil if I want. I would probably plan to add an intercooler and bigger exhaust to add a little power and fuel efficiency if I get one. Sorry to be a bit winded but I thank in advance for any advice. Cheers.
