Gentlemen:

Please explain a "vernatherm" device. Where does it belong in the oil
flow pattern, how it operates,  where I can get one for my Lycoming
engine?  

 I have had a very difficult time with the low oil temps in my spammer
during cool/cold wx ops. Winter kits, taping off the cooler, constant
removal of the cowl and trying to guess the amount of cooler to leave
exposed for that days flying are poor alternatives to what everyone but
myself seems to take for granted with the installation of a
"vernatherm". I would be happy to install it and go through the field
approval process if this would help alleviate the problems.

 My oil temp hovers around 180 during winter ops and you can see the
condensation of H20 on the dipstick after flight!  I am changing oil
much to frequently as I would rather the expense and time of oil changes
than collecting the water inside the very expensive engine.  

In all my years involvement with many different types of industrial
engines, I have never heard of a vernatherm, so yes I feel like I missed
the boat,  but I'm hoping that those of you with a little grin on your
face as you read this will remember the "south park credo"..."there are
no stupid questions...just stupid people."  I don't really mind showing
an occasional ignorance.  Thanks to those of you that can take the time
to formulate a response.  You are welcome to email me direct or respond
here if you feel this is a subject worthy of this excellent forum....  
Regards....Jeffrey B. Chipetine
