Hi Paul, I'm in Newhaven so next door really. It'd be great to see your rebuild and meet a local fellow Landy enthusiast although I doubt that I could advise much as mechanically I'm quite a numpty. I did take a V8 apart and back together again but that was under strict supervision.
I've have currently a 1985 E-reg 2.5P 90, was running beautifully but has given up the ghost recently, something ignition related, hopefully a poorly battery. In the past I've had a V8 90, 2.25P 90, V8 110, V8 RRC, S3 2.25 NAD 88, and a S3 2.25P 109. I must be out of my mind!!!
Only free weekends; give me a PM if you want to chat more.
