Re: 443 high oil pressure - cause for concern?

Sorry to be late to the dance on this, but every 1920s Packard I've seen runs fairly high oil pressure, seems to be normal on these cars. My '29 runs straight Lucas 30 weight zinc-infused oil (I'm in Louisiana, it's always warm here), and the engine idles at 35-40 psi, at speed it usually stays at 40, at higher speeds it will go to 45 or 50. Been driving it like that for four years, it's never caused a problem. Friend in Texas has a '30 coupe, it does pretty much the exact same thing. I don't think you've got anything to worry about. Fantastic car and love those headlights!
