[Healeys] Oscillating oil pressure needle

[sbyers at ec.rr.com]

Richard, check the nut on the oil pressure hose on the back of the gauge.  If the nut has loosened, it may have allowed the air in the line to bleed out.  The air will dampen the vibrations.  Disconnect the nut at the gauge to allow more air into it, then retighten.

Richard,
Any noises or things that seem different?
If not, I would suggest that you swap in a different sensor unit and or a Oil pressure gauge. 
 
Respectfully,

Fellow Healeyphiles,
     Today my '65 BJ8 showed a rapidly oscillating oil pressure needle whether at idle or at speed. Oil level normal says the dipstick. The oil pump probably has 130K of use. Is this new finding a harbinger of worse things to come? Need I do anything about it? Thanks for any advice offered.
