I just discovered this morning that I do not have the baffles that run
along the bottom of the case halves. I did not know that there were any,
but looking at another 0-200 installation, I noticed them. I will try
this next. I do not want to add an oil cooler. My upper baffles are
close fitting and sealed well.

Aaron,
With my A-65, that I rebuilt under the eye of my AP mentor, recommended
an oil that we use in work. "Terressic #68" which is a pure mineral oil
with viscosity of 20. He had me run that quite a number of hours. Then
went to the multi vis aircraft oil. I have eyebrows with no lower
baffleing, including no "gull wing" baffle under the gap between the
cyl. bottoms.
My oil temp guage starts at 120 or 140, And only twice in 75 hours of
flying has it came off the lower stop.
Did you break the glaze nicely on the cylinders? If not, you'll get
heat , and the engine will always use oil. I rarely add oil

Subject: Continental-List: 0-200 oil temp
I'm looking for some help on my freshly ringed 0-200. The oil temp
climbs slowly beyond 200 degrees. This is especially true when the
outside temps are greater than 75 and when the RPMs are over 1800. There
is 15 hours on the engine since new rings and crank, 220 SMOH. The CHT
during climbout goes to 400 or slightly higher and comes down to 325-350
at 1800 RPM. I have Phillips 20W50 oil now, having run straight mineral
oil for 7 hours (the oil pressure was a little low with the 30 weight
oil but now is good). I opened up the front inlets openings(this brought
the CHTs down but not the oil temp), Installed a 'Cool Collar' (w/ fresh
air duct on the filter) ,which helped a little, Removed my bottom cowl
flap completely, which helped a little again, and added a scoop to bring
fresh air onto the sump, again this helped a little. But in 80 degree
weather above 1800 it still climbs over 200. My question is, Do I add an
oil cooler now or hope that break-in will bring temps down enough that I
don't need a cooler. The engine is installed in a Zenair 601. I had been
told that I should not need a cooler by numerous people. I have checked
the gauge and it is accurate. Anybody have any advise?
