I am starting to see some high oil temperatures in my RV-6 (O-360 A4A). Usually they are 185-200. The past few flights I saw consistent 225. I removed the vernatherm and tested it several times. It opens at 185 like clockwork. However, it is an old version and I ordered a replacement as per lycoming.
I have been reading several threads with similar issues. It seems that airflow through the cooler is a major issue.
I have attached pictures of my existing setup. There is a 3" tube running from top of cyl #3 to oil cooler. There is a cold weather block plate that is controlled by a cable on the console. It seems to me that the block plate is pivoting in the wrong direction and that, when opened, is impeding air from flowing through the cooler.
Here is what I'm thinking to do to solve the problem:
1 - install the new louver kit
2 - remove existing cold weather pivot plate.
3 - build & install fiberglass channel from bottom of oil cooler and ending at top of louver. (Do I need to add downward facing louvers to this channel?)
4 - replace 3" tube with 4" tube.
Thoughts? ideas?
Thanks in advance! - Wayne
