1932 Austin 10/4 oil pressure

What is the correct oil pressure for an Austin 10/4 and should it vary with revs. Is 30psi at tick over hot and cold an indication of a problem?

Hi David

Your 30psi oil pressure is fine at about 35 - 40 mph.  The oil pressure relief valve must have been set at 30 psi.  However 30 psi at at tickover when the oil is hot is a bit puzzling.  Normally I would expect the oil pressure to drop to about 15psi at tickover when the oil is hot.
Are you sure that the oil is really hot. It probably takes about 30mins of driving for the oil to become really hot!
Or your bearing oil clearances are very good!

Thanks Bill. Maybe oil wasn't very hot but nothing to worry about then.
