​In the midst of the full time preparation of the OUMF rally Riley for Abingdon Stages and the Ypres Rally, the Summer of Love race weekend at Brands Hatch circuit in Kent snuck upon the OUMF team fast. At the Donington Historic Festival, a number of worrying pieces of steel shim were found in the racers oil after the post-qualifying oil change. Due to the lack of options on the table, and the fact that the engine seemed to be running ok, it was decided to race on, and give the engine a full inspection after the event. It was suspected that the shims could be from behind the timing sprocket, since the front pulley was loose on the crank and may have caused some damage.
