Now that my water pump is working and the
oil cooler isn't the primary engine cooler
the temps are more in line.
On a normal drive the water temp gets up to about 80*C. In "town driving" the
oil temp will eventually climb to about 70*C - 10*C below water. The longer I go the
oil catches up, and at a steady running condition of about 3000RPM-3500RPM ( 75-80MPM) the oil will get about 90*C.
I think the message is that these are not commuter cars. You really have to take them on a 2 or 3 hour drive to "warm them up".
My favorite drive is now from Lyons up Hwy 7 to Estes Park (with a side trip in the park weather permitting) then back down Big Thompson Canyon - and put it in neutral and rev it through the narrows).
The sound off the walls is classic muscle cars reverberation. I wish I could rent Hwy 34 through the canyon for about an hour.
