Kelly,
After reading Al's post, I need to make a clarification on my previous oil
temp information.  The 245* temps were *after* the cooler, at the oil filte=
r
pad, so who knows what they were coming out of the engine.  Over the last
year I've instrumented my oil & water cooling systems so many different way=
s
that I sometimes get confused as to what I'm reading on the EFIS & EM-2.
Presently, I'm taking oil temp readings after the first oil/air cooler, the=
n
after the oil/water exchanger (as the oil enters the engine).  I do this to
monitor how well each of the oil coolers are working.  Sorry for the
confusion.

Mark S.
