The fact that it did anything at all indicates a vacuum leak which should be
rectified. Flooding the area with liquid combustibles can convert an air leak
into a fuel leak and if the carb has been adjusted to compensate for the air
leak then adding extra fuel where extra air was before will cause the mixture
to go way rich.

First thing is to measure the oil pressure with another gauge. It is
possible that your gauge is reading low. (if you are lucky)
Next thing is to check the oil pressure relief valve. The spring may be
broken or it may be miscalibrated. Or the plunger may be stuck open.
Next replace the oil filter. It may be clogged.
Do you have one of those head oiling kits? If so, remove it. See if that
makes any difference.
All the above can be done without disassembling the engine so check these out
before tearing into it.
