MM Series Oil pumps
Posted: Thu Oct 04, 2018 3:57 pm
Bryan mentioned that some people needed parts for their oil pumps. Overpressure valve springs?
Anyway, As Bryan also mentioned he had low pressure and a hissing sound, here is a photo of the pump showing 2 places where oil could be firing out. Yellow is where oil pressure could be leaking past the base gasket and Red where the oil is coming from the stuck overpressure valve.
Any thoughts?
