oil level

jude116057 · Mar 30, 2016

my oil level in my 1655 increased ~1 gallon over a week with minimal runtime? I have eliminated the mechanical pump as I just replaced the motor with a 310 out of a 1755. it didn't seem to have a bad bladder so could this be coming from the injection pump? my coolant level was ok so I don't think it was that. thanks in advance

If the oil looks thin it can be caused by the injection pump. When the retainer ring starts to fail the bits start restricting the return fuel flow, increasing the housing pressure, then forcing fuel past the shaft seals. Repairing the pump with a new pilot tube after a complete tear down/inspection and reseal may be needed.

It was the umbrella seal my first repair of this did take some time but well worth the effort
