[Just a Six??]

Hello all, First time here!! Great Site!!
Why is oil pressure 45-50 at start up but 5-10 when hot?? Using 10-30 with oil pressure plate & spring kit I got many years ago from GSCA or Kirban. I don't remember who. No leaks anywhere. Any Ideas??
THANKS

What do you consider "hot"?

Also - might just be worn bearings. frown

Try 10-40 in the summertime..
