They have a lot opf wear parts that are far from heavy duty. Our Ford 6.9 and 7.3 IDIs have the same DB2 pump, except it turns the opposite way in the IH/Ford diesels as Chevy/Detroits. That said, we have a few folks over at the Diesel Stop running WVO/SVO in 7.3 and 6.9 IDIs. Some of them have a lot of miles, but will the pumps last? At worst, your're risking a $300 injection pump. Although I like IH diesels myself, I will say that the 6.2 Detroit is a tough engine and will give you many trouble free miles if you keep up on the maintenance. I woukd make and run biodiesel myself, since this is already an iffy pump and WVO is not tried and true with them.
