You live in Sacramento CA. Do you often drive in 50 deg weather?
As I posted in Fred's thread, I've had 2 Mocals with no increase in
oil temps in cool weather. Save yourself a lot of work plus the chance of leaks and cancel the idea. Drive harder or drive in lower gears and you will get
oil temp up.
If you're bent on the idea, then get the Canton that Fred has which seems more effective at getting a little temp in the
oil.
