Ben the 1980 300SD Lives!!!

Gentleman Ben, the beloved 300SD, has now recovered from the unpleasant

3-piece camshaft episode (change out your vacuum pump before this happens to you!). After almost 2 years in the home hospital, a good used engine, rebuilt transmission from Adsitco, a double buff & wax, and a lot of TLC it now ticks over like a sewing machine and is ready for daily driving.

Questions to the group to aid final recovery:

The heat now doesn't want to shut off. Without doing a lot of troubleshooting I am thinking that something in the heater servo valve or the control unit may have gotten stuck or corroded during the extended idle spell. I've already corrected some electrical glitches caused by corroded contacts in the lighting. Are there any typical failure modes in the climate control system? I am about to go through the CD to gain familiarity.

Does anyone out there rebuild the servo valve and control unit for reasonable prices? The options I see at Rusty's and Performance Products and Adsitco seem pretty high for these parts ($250-$1400).

Thanks again to Mr. Lambert and other frequent contributers for the advice I've gleaned over the years.

Next in the emergency room is the 1986 300SDL with the possible cracked head.
