advice 4.3 caddy diesel

Going to look at a 85 caddy with a 4.3 in about an hour. Any advice as to things to pay attention to other than the normal would be appreciated! Thanks

GF wants it so trying to stay positive here. Plus just drove quite a bit to get it. Almost th ere. It has brand new tires so that's a plus. Not for a daily driver but more of a novelty.

As a novelty and if its cheap and seems solid it may be worth it. I have looked at a few but they wanted too much and I really already had too many cars.

It is kinda a 5.7 with 2 cylinders missing. I believe the regular V6 was actually that. The transverse ones I think were better. Those had a different head bolt layout and several other improvements along with the different overall layout and mounts the transverse mounting required. If they would have got around to applying those improvements to the 5.7 they would have likely had a good engine.

They made a lot of changes to the electronics for 85 so I have heard there are some modules and such that are very hard to come by. Same thing for the V6 specific parts, there were never tons of them out there so not much reproduced. V6 diesel in a Cadillac was very rare being a one year only thing.

And to Smakzed, Really? A gas engine? I expect to hear that from people that don't know anything about diesels but someone who apparently has diesel experience? Yes there were issues and some of them related to them trying to use existing parts from the gas engines but it was far from a converted gas engine. The were a lot heavier than the gas engines. Used bigger main and rod bearings, had to have a place for the injection pump and drive. IF you are building a diesel engine to fit in cars seems like making it about the same size as the gas engines and using the same mounts as the gas engines may be a good idea? Same idea with the 6.2, they shared a lot of basic dimensions with the gas engines because they wanted an easy fit in the trucks.

It was a joke. I think JC got it

My jokes have been falling flat lately

Ahh.... Guess that is what I get for not hanging around the 6.2 section more.

So the real question is did he get it?
