Good to know as well. I'm crossing my fingers but I just found a om606 in a rear ended car on letgo that looks very nice otherwise. Long as it's still there in a couple days I'm scoring that thing! So I'll be holding off of 603 injectors. My home brew fuel seems to have cleaned up the sporadic lopey idle for now too. It may have been from sitting for most of the last couple years i guess too. I'm psyched about the om 606 though!! I can get the 717.668 all situated on that motor and swap them In together. Just swap the pump when I'm ready to do it.
