I went back to the engine and checked the remaining rocker arms and found that the exhaust rocker on #5 was loose as well. It was not quite as bad as #6 (1/8") but very loose. Are these normally tight like the rest or is it possible that the device has collapsed due to the fact that all the oil has drained from the engine? It has been upside down and in every position while on the stand.
Is there a tool that I can compress the valve spring with in order to remove the rocker arm and then the compensating device without removing the cam?? Any idea where I might rent or purchase said tool?
