Are ther different Vernatherms temperature ranges available?
My engine has a new Superior SL53E19600 Vernatherm and it is stamped with 85 C so that converts to 185 F and this was installed during the engine rebuild. The engine now has 20 SMOH..
The engine oil temperature on my airplane since the rebuild has been consistently 230 F in flight and I just assumed that the warm oil was the result of tight internal engine tolerances and the rings allowing blowby to cook the oil.
The engine before it was rebuilt had what I presume was a Lycoming Vernatherm and the oil temp was always 180-190 F rock solid. The only thing different now is the rebuilt engine with the new Vernatherm.
I did a test the other day by taping a thermocouple sensor on the oil cooler inlet and outlet lines and I could watch the digital temperature indications and I performed an engine ground run up and when the oil temperature was 195 F and increasing the inlet to the oil cooler was still ambient temp and then it started to show the oil inlet port got the warm oil,
So the Vernatherm is indeed opening however it seems to open a bit late.
Is there a Vernatherm that is 175 to 180 available?
THANKS!!!
