[Healeys] no oil pressure

To paraphrase a summer saying: "It's not the heat, it's the stupidity".
The spin-on adapter was upside down. It now has "TOP" stamped on it, in
an attempt to save me from myself in the future.
When in doubt, read the instructions. I have a couple of extra adapters
(with instructions) that I bought at Jack Summer's estate sale. The
1/2" drilling between the two counterbored holes goes at the bottom.
Oil pressure is about 60 psi cold. I guess 90 degrees is considered cold.
Thanks for all your assistance.

If not normal, something seems plugged downstream of the filter allowing pressure to build-up and stay in the oil system. If the oil galleries diverge immediately downstream of the filter, the culprit is most likely in the immediate vicinity of the filter. The first thing would be to check the spin-on filter adapter as others have suggested.

Spun the engine on the starter for 20 seconds or so and removed the filter. It had oil in it. There was still pressure in the system and it "popped" as I loosened the filter.

I don't think that the adapter can be installed so just one hole blocked, but I'll remove it to confirm it's on correctly. It's easy enough to do.
