OM 606 idle miss and excessive blue smoke
X Double Dot any idea how much leakage is normal? Couldn't find any threads anywhere that discussed this. it would be great if someone could disconnect the return hose and hold it vertical and say it takes ~20 seconds at idle to climb ~10 inches (or whatever it is). Ideally i know nothing would leak out, but since these are metal on metal surfaces i know some rate is to be expected. If it's really high, I was wondering if this could lead to retarded timing, as the pressure wouldn't build as quickly and the injector would pop slightly later?Not sure if your referring to when your pop testing or when the vehicle is running. During pop testing there should be no fuel coming out of the return ports if everything is sealed in the injector body. When running the vehicle with the return hose off the fuel filter banjo there will be a steady flow of fuel at a low pressure.
I'm going to buff the applicable surfaces on the injector and see if it reduces any of the bypass when i replace the nozzle on the leaky one.
i was successful in getting a prechamber out last night. Any tips for inspection/re installation? I assume wire brushing them off and maybe a light coat of copper anti-seize on the pressfit portion of the surface?
