Now, this is the part i forgot. The bottom pulley has a V cut out, line that with the 0 mark on the black pulley cover. Its easier to mark the V with some TIPEX. The top pulley arrow will now (or should be) inline with a small dimple on the head. You can line these up using a spanner and turning the pulley clock wise. It will Feel tight but will go. When these are lined up un tension the pulley tentioner. NOW! Remember how the pulley tentioner sat as this is vital and can be put back incorrectly, take photos if unsure.

The valve steam seals are pretty easy too. You WILL need a valve steam spring clamp at this point (usually around £10 from motor factors) Its straight forward, remove the rocker for each valve. This is done by removing the nut which holds it in place. Each rocker will feel loose at TDC (top dead centre) this is achieved by turning the crank like before when setting timing. When the rocker feels loose by shaking loosen that nut. Clamp the spring then remove the seal and replace. Its been a while since i last did this too so take your time incase i missed a step. DO EACH ONE AT A TIME SO NO CONFUSION IS OCCURED.
