I just picked up my first W126 for $250. It was purchased "as is" because it wouldn't shift past 1st gear. Unplugged the kickdown switch and that was fixed. then a few other issues (no alternator, etc).

But now that that's all working I finally got it home (1 hour plus drive). Anyways, I noticed the dash gauge says ZERO on the oil pressure at idle and only 2 at 3-4k cruising speeds. So... that's not good. The car was run on SVO (stock fuel system). Anyways, where do I start. My guess is to second opinion the oil pressure (i.e. make sure the gauge is telling me the truth). But not too sure how to go about that.

thanks for any ideas.
