[Healeys] Oscillating oil pressure needle

[Richard Jim Hockert]

Either worn oil pump or worn bearings can result in pulsating oil pressure.

Unevenly worn bearings can allow leakage in specific positions during rotation, which will result in pulsating oil pressure, OR

A worn drive gear on the oil pump spindle or camshaft can cause the oil pump to pulse.  

Either condition will require inspection inside of the engine - ugh…
Best regards,
Jim
