Re: Oil Pressure Volvo D3 I - C

Hi Dirk;


We had a similar symptom, but did not have the thin oil that you are experiencing. So, I do not believe your issue would be the same. As others have suggested, a potential source of diesel in the oil would explain the low viscosity.


In our case, it was the oil pressure switch (sensor). I would recommend removing the oil pressure switch and installing a temporary pressure guage, so you can eliminate the possibility of a bad switch. I believe at idle, you should maintain 1 bar of oil pressure.


Happy Sailing;

Hi all,


since yesterday I have an oil pressure problem on my AMEL 54#96.

When I go from normal speed to idle, the oil alarm starts.

Of course, this doesn´t happen in the port but between the islands in Croatia.

My German Volvo expert suspects that the oil is too thin.

Diesel has probably gotten into the oil.

That´s why I changed the oil. More than 7 liters of very thin oil came out.

Then the engine ran again without an oil pressure alarm.

But today, when I switched back to idle, the alarm went on again.

I appreciate any advice or experiences.

Thanks a lot,



Currently Croatia close to Dubrovnik

I know this has come up before, but I am servicing the main sail furling motor and worm drive.

It is all well but the top shaft seal should be replaced.


Shaft into the worm gear is very tight. Soaked it in diesel for some hours, hesitant to hit it. Plan to find a press to press it out.

Does anyone have a better idea?
