The Westerbeke oil pressure reads:
Start up diesel 65 psi
20 minutes operation 30 to 40 psi and drop to 20 psi a few times at 2200 rpm
Throttle back psi go up to 50 to 55 then drops down to the 30 to 40 psi
range
Change oil sender and unit two years ago and no problem for that year.
Last year oil pressure varied like above...he check sender and unit and
said it's seems O.K. resistance ...
Westerbeke rep said bad bearings given the age of the motor......1978
Bill
1981 300 TD
p.s. needs to check sender, unit, wiring etc....
bearings
goes from 30 to 50 psi

If its above .3 bar its OK.
I'm no Westerbeke expert, but .3 idle sounds low, and .3 cruising
sounds deadly. I think it's normal to put a .5 bar low oil pressure
alarm switch on an Atomic 4 gasser.
