A strange on going issue. I have a 292 that I rebuilt several years ago. It runs great, but every year when the temperature drops, my oil pressure goes nuts. When cold ,when fired up, a steady 50lbs. As it starts to warm and I start to drive, the mechanical guage ( 4th one) will start to slam up to 80-100 psi. When it gets up to temp, it settles down to a steady 40-55 lbs. I run 10-30 oil, and have checked the relief valve in the gear type pump. This has gone on for years and have never blown out a filter or anything, but it does have me scratching my head at this time of year.( temp in the 40s). Hmmm

Is the steady 50psi at cold idle? Is the 80-100psi at idle or cruise? when it settles down to 40-55psi, is that idle or cruise?

Like I said,I am on my 4th gauge. When cold on start up, a steady 50. As it starts to warm,(I am slowly driving away)the gauge will start to rise with rpm. Within a few mins. the needle can creep up to 80,then jump up to 100 and back to 80 a few times. Within a few mins.,as the temp rises, it settles down to a steady 40@ idle to a max of 60 cruising. Seems temp and viscosity are at work ,but how?
