The tips of all the teeth on the Crankshaft sprocket are missing and the timing chain has worn very loose. The camshaft sproket teeth are also pretty worn. No wonder the valve timing was able to slip.

Sounds like a fairly easy fix then, timing chain kit and a pair of new sprokets to be ordered and I can hopefully get it sorted next weekend.
Only other part to order is a new water pump housing gasket, the water pump housing had to be removed to get the timing chain cover off due to a pretty crap design by Triumph...
