skipperpete - thank you very much .
Have not yet been able to find photo
or drawing of what appeared to be streaming out oil ... there is a bronze
tee coming out of the block. The upper tee has a cylinder with a domed top and a wire, the lower tee a fitting with a wire that seems to be what activates the oil pressure gage - there is no visible aperture for the oil, but perhaps it is being, as it appears, pushed through electrical
Access is constrained, but this apparently “ solid” terminal sure seemed to be source of leak ..... ! .... ???
