Re: '35 Standard 8 Oiling issue

Based on long experience with essentially the same engine, I recommend you set the oil pressure relief valve to give about 50 -55 psi maximum. This may occur at cold start up and modest engine speed, or at road speed with a warm engine and proper viscosity oil. But whichever, make about 55 your max before the relief valve bleeds off pressure. Whatever pressure you get a hot idle will be a function of bearing clearances, etc. and won't be changed by resetting the relief valve anyway.

Another item that may be at risk from excessive oil pressure is the oil cooler, though the 35 and up unit was a lot more robust than the 1934 unit. I've generally used gaskets from Egge and can say I've not had any problems with oil seepage at the rocker covers. I wouldn't be reluctant to use a gasket sealer, or even a slightly thicker gasket material if you think the surfaces don't mate quite perfectly.

BTW, your vehicle is an "Eight", not a "Standard Eight". Folks still tend to use the name, perhaps to differentiate from the 120 and Super Eight, but the use of "Standard" as a descriptor went out in 1932 I believe.
