Well, I got the car back last night finally. Upon looking at my old head, I see why they didn't want to use the old prechambers. They could not get them out. They totally buggered up one of the lock rings and it looks like they started on a second before giving up. Last time I ever take any of my cars (unless under warranty) to anyone else for repair. I can waste a lot of time and money messing up parts myself and still come out ahead of where I was on this deal.

What's the story on the shorter glow plugs? As far as I can tell they used my same glow plugs from before with the new head. I did notice it started a little harder than normal this morning, but at this point just having transportation is a wonderful thing. I don't dare question them about the glow plugs (or I will probably lose my car for another 2 weeks while they figure out how to change them), so I guess if I need different ones I know what I will be doing this weekend.
