I bought a 1935 Chevy Standerd over the winter, It has original engine and has 15 lbs oil pressure when cold and after driveing for 1/2 hour it is at 2 lbs, I am thinking on changing oil and useing staight weight 30. I noticed what might be a screen where the oil pressure line comes out I will investagate. Any Ideas on this.

This is what the recommendations and normal pressure was from the original Chevy maintenance manual for your engine.

I used seafoam on the engine, drained , put 15-45 in with a zink addative. 12-15 cool and 5-7 warm @45 mph had it going 60 but at idel when warm I am at zero, is this OK or do I need a pump.

My .02...if you are using the dash gauge...you might want to try an external gauge first?

When my 32 was stock it would show 0 pressure at an idle when fully hot and I never had a problem. I went with the pressure reading at speed like the manual stated. If you want to read an interesting article about the early Chevy splash system take a look at this link
