Good stuff Geo, i was hoping for a talk but u kept going round and around and around all day lol, u did smoke a fair few cars tho, i had the teg on but i broke the clutch master cylinder on the first run
its to tension the cam gears, the head can b a wee bit noisy if u dont do it. u need 4 hands and alot of swearing lol, it doesnt need to turn that much, its hard going but it can b done
if u take the rocker cover off, the exhaust cam gear is on the end of the exhaust cam, same with the inlet cam gear, its on the end of the inlet cam, you will see the timming marks on them gears.
