Thanks very much. So the piston would bend the pushrods via the valves rather than the valves actually bending? That would be good news. I'll do a compression test once I've replaced the belt to see if the valves are seating properly.I'll search the web for a contact for Leyland DAF, however, if you know how i can find them that would be extremely helpful.
Thanks again. Once again, a Land Rover forum comes to my rescue.
