Low oil pressure 356 Volvo penta 8.1

[barbarab]

looking for possible causes and fixes. Port engine showing low oil pressure. Oil changed 8 months ago.
Levels good. Oil looks good. Engine temperature normal. has anyone else encountered this issue? Would love ideas on what to look for?

Is the pressure low just at idle or at cruise rpm? What pressure do you consider low? What weight oil? How many hours since last change? and how many hour on the engines?


This info will help other offer ideas.

Thanks.

What Tom said.

Have you ruled out a gauge and or sender fault? Pull the sender and put a test gauge there to get a true reading right at the engine. This will tell you if you really have a low pressure condition or if it's a problem with external hardware. You also have two engines so you can swap the gauge with the other side and see if the fault follows the gauge. If it doesn't, swap the sender and see if the fault follows it. If the poor reading follows either one of those components, you've found the problem.

It's a start. An engine serial number would help too.
