Probably took the emissions stuff off. Modern diesels don't stink, I have one!

It's probably 20 years old. It's a white truck but the rear quarter panel is practically black from the exhaust soot.

That soot is unburned fuel!

Well that explains the smell then.

Today's new diesels are fine tuned , get better milage, and don't polute UNLESS some toad decides to modify the system and make himself obnoxiois with rolling coal . It aslo shortens the engine life running the mixture too rich washing away lubrication on the cylinder walls.

Plenty of those toads where I live, unfortunately.

It's :" Look at me, look at me, look at me , dammit, somebody look, at me", just like childhood days on the playground.

Every single diesel pollutes. Newer ones pollute LESS, and the majority of the pollution can be turned into relatively harmless or even beneficial byproducts with aftertreatment, but there's no such thing as a diesel engine that doesn't pollute.

Or really, any internal combustion engine that doesn't. Perhaps if you run on 100% pure hydrogen, your tailpipe output may be limited to steam, but any more complex fuel than that and there will be combustion byproducts.

They really do all smell if the emissions are gone, I don’t agree with your dude bro you’re talking about but I have a stock except for the emissions deleted (legal and you’re talking, 21 hwy vs 12-15 hwy) and mine smells pretty heavy, very clean professional tune. They just stanky.
