Takimaya, actually it was your "3K" that prompted me to start this thread. It just got me thinking about how much I have spent on my '80 SD. From there I started looking at the records and thought "well that's not really a repair, that's maintenenace". I didn't realize how much of a bee's nest I stirred up with this. For my SD, I replaced the driver's side spring frame. To me that's a repair, whereas replacing glowplugs would be maintenance. Granted there is no interval for glowplugs, but I look at them like sparkplugs, they wear out and get replaced.
