I am reaching out here for suggestions about the 0200A @2600RPM.
At power settings at and below 2500rpm, the oil temp is steady at 180-190. However, the oil temperature increased to above the redline (450*) @2600rpm.
Decreasing the RPM to 2300), reduced the oil temp below 230*.

Engine inspection confirmed proper cylinder baffle installation.
There are no oil leaks.
All engine wires and hoses are installed IAW the IPC.
The filtered engine oil (5 quarts) has 45hrs since the last change.

Ideas about what to inspect next in the search for the cause of high oil temp at 55% power are requested.

Best.
