I agree Castrol 20/50 GTX is the only motor oil I use in my sprites. 20 lbs of
oil pressure sounds low to no matter what oil you are using. The way I check
for low oil pressure is first check the pressure valve, When you first start
the car cold the gauge should show where it is opening around 65 lbs in my
cars. Next I remove the valve cover and start the car when warm. You really
should be able run it with the cover off and not have oil being thrown all over
the place. If both of those check out ok then its the rod & or main bearings.
This is also in order of cost.
(1) Replace pressure valve cup with ball bearing ala Vizard (I think its 5/16
or the same as a bearing out of a rear wheel bearing) around 10 cents.
(2) Get rebuilt rocker assembly from local machine shop for around $50 exchange.
(3) been there done that, big bucks even if you just slap them in.
