I had those high oil temps. When I took out the vernatherm and inspected the 
seat it looked like it had been cut with a dull tool. I ended up getting a 
replacment cooler and vernatherm. Now the temps run at 190 in climb and 180 
in cruise. In the fall I have to close the oil cooler door to get it up to 
180.
