Engine knocking

[Ben]

If its the earlier type of engine the correct torque is crucial to drive the oil pump. If its the later type its key wayed so has less of a chance of slipping

Surely none of the engines have a cambelt crank pulley without a key? If it slipped at all the timing would be out and the engine shagged..

Anyhow the knocking has gone, must have been something that needed freeing up. Thanks for all suggestions and advice.
