Thanks for the responses....
After re-reading the haynes manual tonight, we first lined up the 2 dots on the cam, then adjusted the cam pulley to line up the relevent notches against the head, so it appears that the pulley is correct.
We now have a problem where by the cams dont want to move when fastened down in the head, some sort of hydrolic lock...? Anyway, with fading light and temperatures, we've decided to call it a nite, hopefully we'll get the cams moving tomorrow and the engine running again.
Annyone know what could be causing the cams to lock...? If you release them, you can push the lifters and they all move freely..?
