The voice of Volvo D2/55 la 3 fold
Available immediatly in Martinique.
Do not want a turbo on my marine engine, useless & more prone to failures.
Recent model , widely spread, will find parts for a while.
Tied up with agents for service & parts.
I still might give up on replacement here in martinique & keep on looking for an oil pump to do repairs, then sail to better deal location.
Note : old faithful M 4.154 is still reliable & so easy to run & maintain. Regrets

Hi there Christian
As a fellow maramu owner with an older engine I’d be interested in your thoughts about the Volvo D2/55 as a replacement vs other alternatives.
Size, simplicity, cost etc? What led you to choose the Volvo?
Many thanks and best wishes
Thanks for concern & assistance Bill
guess all the advice & analysis of fault helped me come to the conclusion (already uderstood & applied before) that there is no shortcut when repairing engines or sailing boats.
Oil pump is at fault - 100% sure
camshaft is unllikely eve though showing some wear on,poppets.
I am now in Le Marin, waiting for a firm quote on one Volvo D2/55 available for fit up ... on solution even though unplanned this year;
I am also looking for one Perkins Oil pump .... could replace in situ at no great cost & would postpone replacement by new engine to 2019
or back to Europ in April & do a change over of engines with Perkins or else ... Selling back my 'Old Faithful'

I am afraid I have no good ideas that match your symptoms! Since you have both the gauge and alarm reporting low pressure, I have to assume it is real and not a problem with the measurement.
Sometimes low oil level can cause low pressure at high rpm as the pump sucks so much oil out of the crankcase it sucks air, but you checked that.
A stuck open pressure relief valve that resets itself when the engine shuts down could be an an issue, but that seems unlikely.
Maybe someone else has an idea or two... in any event do let us know what the solution turns out to be!

Yes - oil pressure gauge and l'os pressure alarme on
When oil pressure below 1 bar, alarme nées
Oil pressure drops quickly at 2000 rpm
Oil pressure remains stable when low or normal
Oil pressure remains low when reducing speed from 2000
No loss of oil single de started.
Ran 1hour maneuvring in port at 1300 rpm at 2 bars, went To idle after 1 hour at 700 rpm with 1.1 bar oil pressure.
Did not risk acceleration.

Losing oil pressure at high RPM and having it come back at low RPM is a bit of a puzzle to me. There are ways it can happen, but they are a bit exotic
Do you have an oil pressure gauge AND an low oil pressure alarm?
If so, is the gauge showing low pressure AND you get an alarm?
Does the oil pressure drop quickly at 2000RPM or does it drift down slowly?
Is it stable, or does it bounce around?
Does it come back quickly when you reduce the RPM, or does it stay low?
