Today I replaced the timing chain on my 300CD. I also adjusted the valves, changed the oil, new coolant, new glow plugs, new air filter, and a fresh bypass hose on the thermostat housing to water pump housing.
Before doing these repairs, the car ran ok. It had kind of harsh shifts and I had to keep the idle set to 800 to keep it smooth. There was also excessive smoke from the tail pipe.
After finishing things up today, the shifts are smooth and the power/pick up is far better than I was hoping for. I need to wait for daylight to adjust the idle back down to 650-750 and readjust the rack damper bolt while I can see any changes in the smoke at the tail pipe.
I'm curious to see how this is going to effect fuel mileage.
