This motor has always idled warm (185) at about 35# gage pressure @ 900 RPM. It generally runs 60-62# gage pressure cold and 48-52# warm at any operating RPM. Now I'm getting abour 42# cold at operating RPM and 15# @idle. The gage presure goes to about 40-42# at operating RPM warm. I'm not so worried about the
oil pressure as I am about the change. I also need to figure out where the heck the plugs came from. THat really bothers me.
