When I returned, the injection pump was in pieces in a box. I asked them why they took it apart, and they said it was bad. I asked them why it was bad, and the person at the counter said, "I don't know, it's just bad. That will be $100."

I asked why it was taken apart when I specifically wanted it put on the Bosch test station. Their answer was, "Oh, we got rid of that equipment a long time ago. We had to take it apart to see if it was good or bad." So, I had to pay $100 for a pump I brought in for someone else because I wanted to have it tested, and it came back totally useless.

Also, I had the injectors in my 300SD rebuilt there. As I recall, three of them leaked between the upper and lower halves, so they had to redo them. Then one of them still leaked and the technician told me that it was my hard lines or the rubber return hoses leaking, which I knew it wasn't.

I had to get pushy in order to get them to fix it. When they split the injector halves, I could see why it was leaking--there was a lot of scale they hadn't cleaned and the technician bead blasted if off. After that, it didn't leak.

I also didn't like the technician saying, "Pop pressures don't really matter on these old injectors." They also wanted about $70 each for heat shields that I can get online for $2 each. So, if you use them, don't let them take you for a sucker.
