Hi Paul- Great "Diesel Injection System Troubleshooting" article! If you felt up to continuing, I'd sure like to put dibs in that it cover some of the in-vehicle-correctable fuel leaks.
Newbie here. Regarding an IP fuel leak at housing cover seal; Specifically wondering if this is a straightforward R&R of Housing Cover...or am I going to be releasing spring loaded plungers, detent balls, foil shims & such when I pull the cover off
? I don't know what magic is contained or occurring inside at this mating surface. Any tips or considerations offered on this procedure would be appreciated.
____________My 1986 Trooper Turbo Diesel is currently without any start/run problems. It leaks quite a bit of diesel from IP while running. I bought a factory service manual off ebay and was disappointed that IP is treated as non-internally-serviceable. I surfed and found postings on this site by which I was pretty confident the CSD was leaking...I installed o-ring kit...I was wrong about the CSD leak (o-ring condition was actually pretty nice).
I re-cleaned/dried the IP exterior and explored source closer. Found your Troubleshooting article and determined what component I was looking at (thanks!). Now I'm confident that the Housing Cover seal is leaking (near the front half) and tracking down.
