Hi all,

After a lengthy drive earlier - i noticed my oil presuure over the 90 psi gauge at idle- as soon as i pull off it goes down to 60 psi- hard acceleration down to 30 - then back to 90….

Any thoughts?

That all sounds backwards to me, I'd be trying to verify the readings. Stick another sender in there and a cheap gauge, something like this .

Check the sizes before buying because I just guessed

Check and clean the connection at the sender it gets very dirty down there and plenty of vibration.
If memory serves (rare at my age) the gauge will go full scale if you disconnect the sender.

Yep, give the contact a clean.
Mine suffers from a bit of oil while my cork sump gasket gently weeps, and if I clean it up it performs better.
I don't get the high, mine drops to zero every so often, then comes back up.

Car drives nicely, so I'm confident it's just the sender signal getting fuzzy.

And it’s always worth remembering that the red light in the dashboard is driven by an entirely independent switch, nothing to do with the sender that drives the gauge.

If the gauge is showing strange readings but the red light hasn’t illuminated, it’s a 99% chance that the gauge sender is faulty or its connector is dirty and your oil pressure is fine.
