Re: Oil Pressure

If you put heavy stuff in the earlier cars and gun the engine on start up in extreme cold it can blow a hole in the crankcase oil regulator passages.

You always can put a bottle of 10w-30 and 15w-40 in the freezer overnight. The V-8 requires splash to the pistons. Keep in mind that the oil pump has to draw that heavy oil through a screen and if the oil starts cavitating you can get foaming that will reduce pressure which probably is what happened here given the gauge wasn't damaged apparently.
