LOL, my personal vehicle tastes are rather eclectic. Sometimes I'll use my M35A2 as a daily driver when I can stand keeping the 50 gallon tank filled! I've also got about half a dozen Merkur XR4Ti's around and also two Isuzu VehiCROSS's, but I enjoy the 240D on the highway as I'm rarely in a hurry like everyone else seems to be. I know where I'm going and I like to enjoy the journey along the way.
I haven't looked at the vacuum pump yet, wasn't really sure if the '81 had a diaphragm thinking that was on the older pumps. The only thing connected right now is brake booster and rack shutoff due to a leak in locking system that hasn't been high on the "to-do" list.
As for the compression numbers I'm still not real happy about my valve adjustment as I always have problems getting the jam nut tightened without changing the clearance. I'm going to set up my aircraft compression tester to get a better idea of what's going on with compression.
