Has anyone heard of hydraulic lock on a 2510 diesel mule. I filled the oil fill to fast and it spilled all over the valve cover a small amount of oil got into the intake through the rubber fose on the one corner of the valve cover it started fine and have ran for several days. it does have a fluttersound to it when you tramp the excellerator in high or low gear but not in nuetral? could this be a bent valve, worn belt, dirty fuel filter. it has 94 hrs on it. any help is much appreciated.
