1987 190D knocking injectors

Year: 1987
Model: 190D (Turbo)
Engine: OM602
Mileage: 225,000

Problem: bad "metallic sound" - sounds like injectors knocking.

Overview:

This knocking exists at low RPM. The engine also idles very rough. It goes away when you rev the motor or place a load on the motor. If I run a thicker fuel (like clean motor oil or power steering fluid - bypassing the main tank), the knocking also almost completely goes away.

I have bled the lines. I purchased the entire injector rebuild kit (w/ new nozzles). I balanced each within 50psi. I have changed air and both fuel filters. I have removed and cleaned the main tank. I have blasted out supply and return lines (to and from) the fuel tank.

It may be worth noting that:

-> The previous owner *may* have run veggie fuel
