<VV> Oil and head temp correlation

[FrankCB]

Stephen,
     Unless your DIFFERENT temp gauges have been calibrated, it's pointless to COMPARE readings from one location to another.  Of course, you could simply switch to a fully synthetic oil and not worry about oil temps being too high.

Could someone tell me if there should be a correlation between the   
head temps and oil temps or not.  I observed very high oil temps but   
normal head temps.  The oil temp, measured with an adapted water temp   
gauge with the sender just above the rim of the oil pan in the block   
was reading 270 (gauge goes to 280).  Normally this reading was in   
the 260's at the highest.  I measured the temps with a laser   
temperature devise and the oil cooler was at 200-205 and the oil pan   
was 240.  The dual CHT never got above 250 and was steady throughout   
the time that this was happening.  This has been a pretty normal   
reading since they were installed when the engine was rebuilt two   
years ago.  I'm also wondering if the oil in the car has been   
stressed and should be replaced.  I'm using Brad Penn racing oil (the   
green oil) and it has only been about 250 miles since the last oil   
change.  I have been using this as the break-in oil before switching   
to synthetic.  I WILL be dropping the shrouds.  I had kept them on   
because it was taking forever to get the engine to 220 in order to   
prevent acid in the oil.  I now prefer to drive for a long time at   
each outing than drive for a few miles and replace an engine.  I   
recently bought a gauge that I can install in the port of the Clark's   
ultimate oil pan that is on the car.  I hope to do this with the   
other gauge still installed for a while to compare temps and see how   
it compares.
