My 939 C has 2700 hr just replaced fuel filter and have found an oil leak L side behind injector apparatus will dig into that and hope for an easy gasket fix. Problem at hand is when working the motor will drop RPMs and lose power this lasts 10- 20 sec and resolves on its own. It will outright die intermittently and I presume this is low oil sensor. filling up brings it back to life. thoughts on oil leak approach ( I can't even visualize exactly where oil coming from even with flexible scope) and the potential causes for transient power loss thanks MK
