Thanx guys, I think I found it
Once I got that useless (broke ) a/c compressor out of the way & the fan shroud off I could see things a lot better.
I want to hook this guage up & make sure I'm getting good oil press. before I tear things down so I can do something about it while it's down if I'm not. Upgrading my oiling system's probabley a good idea anyway. I haven't looked into it much yet tho.
