I SUSPECTED THE OIL PRESSOR SENSOR LOCATED UNDERNEATH THE OIL FILTER
ANOTHER VIEW OF THE SENSOR THE OIL FILTER IS LOCATED ON THE LEFT
CLOSE UP PLASTIC COVER LOOKS LIKE IT WAS BLOWN OUTWARD
The twenty year old Westerbeke 27 engine developed a problem in early October. It was getting increasing hard to start. When I went out to the mooring to bring her into the dock for winter hauling the engine refused to start at all. While I was working on this problem I discovered oil in the bilge and NONE in the engine. I thought I might have found the problem in the oil pressure sensor. As the photos above show It looks like it was blown but, in reality there is a plastic covering around the sensor and the sensor appears to be solid underneath. I have removed the sensor from the engine and will now try and to see if there is a way to check/test this oil pressure sensor.
