Low Oil Pressure at Idle, Volvo AD31B in the Tropics
hookipa wrote:
I recently moved my boat from New Zealand (cold water) to Tonga (very warm water) and I am now experiencing very low oil pressure at operating temperature at idle. The engine is a Volvo Penta AD31B and I am not sure of the hours on the engine. As the engine has seperate circuits for the oil warning light and the gauge, I believe that the problem is not the gauge/sender. At operating speed i get about 50 psi, but at idle it sometimes turns on the warning light. Any thoughts or checks before I pull the boat and remove the engine to check the main bearings and oil pump? By circuits, do you mean separate senders as well? |
