Quote "I remember in the early 1970's a number of V8 distributer caps were cracking & thus tracking between cylinders making the engine fire on two cylinders at the same time making for horrendous knocking as one was well before top dead centre . "
Mate of mine brought a S1 back from UK to Oz late 70s - with a misfire. No 1 dead, no compression. Pulled the head, nothing immediately visible, but eventually found there was a hole burned through the centre dimple. Dropped the sump, replaced the piston and shells, re assembled.....still had a misfire - pulled the dizzy cap - tracking from 2->1 ! Also, when I tried to tighten the head down one bolt sort of stripped the thread - somehow a short bolt got into the hole for an intermediate bolt. After some searching I found a bolt a bit longer than std that would almost bottom in the hole but not quite, and picked up enough threads to get close to spec torque....and it drove away!
