Default OIL cooler bypass

Has anyone installed an oilcooler bypass valve in an RV9?

I am running low oil temps all times.
I have installed a Vans oil cooler shutter on the rear on my oil cooler. It is closed always, except for tests to see if the oil temp dropped if I opened the shutter, It did. I have also blocked the front of the oil cooler with an Alum sheet.

My oil temps with both the front and rear blocked are 160-170 f in climb.

My oil temp gauge is correct at ambient temp. I will check it at my annual next month.

I do have a small Lycoming engine and it runs cool.

Has anyone considered this before?

Sounds like your engine is working exactly as it should. 170 degrees is a great temp to be running at. The vernatherm is already an "oil cooler bypass", keeping oil from flowing to your oil cooler until it reaches a higher temperature.

Many other threads out there discussing this exact topic. And a decent read from Lycoming themselves.
