Hello All,
Brief update. After several weeks of troubleshooting I realized that I have
an issue with the injection pump. When I disassembled the line, everything
looked rusty and frozen and there was sea water in the space. I realized
that my water pump leaked and was letting sea water into the injection
pump. Luckily there is no apparent sea water in the injectors and the oil
is clean that makes me think sea water did not go any further . I am
planning to send out the injector pump to be looked at, then clean the cam
and injector / water pump area as much as I can and put back everything
together.
Has anyone experienced anything like this?
Is there anything else to be done?
Many thanks!
