I have a set of injectors on my NA 616 1983 mercedes 240d. Im going to take a drill bit, that is a tiny bit larger than the pintle hole is, and bore it out ever so slightly. Then i will carefully grind it to a flat and deburr it to help it flow better. After this, i will take some valve lapping compound, thin it out as thin as possible and lap the seat of the nozzle. I will also be doing some minor headwork as well. I will be enlarging the precombustion chamber holes as well. Wish me luck.
