Oil pressure at idle

Hi all,

What should my oil pressure be at idle on my '36 std 8? I get about 35 to 40 when driving (depending on how hot the engine is) but when it's hot and I'm at a light idling it drops down to 5 maybe - always scares me.

In light of what I'm finding with the valves (that's a whole other saga) I'm worried that maybe the guys who put the engine together the first time may have screwed up the main bearings as well.

I just found out the they never machined the cyl head - so it wasn't the head gasket it was that the head was still warped. So now I'm getting that machined flat and doing a full valve job but am a little worried about that oil pressure.

Thanks,
Crin
