Hi Rich, the adaptor fitting in the block to which the oil pressure gauge line connects (1G1814) has a very small restrictor hole through which the oil pressure is fed to the gauge. </div>

If someone, in a misguided attempt to improve oil pressure, drilled out that restrictor (they live among us folks) the gauge can behave as you describe.</div>

<div dir="ltr" data-setdir="false">Fellow Healeyphiles,</div>
<div dir="ltr" data-setdir="false"> 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.</div>
