REFLECTOR: vernatherm

[Grover McNair]

Thanks for the response. I responded to Brian's letter explaining where I am
measuring the oil temp. My bypass valve has a fitting on the side that feeds
a line going to the flywheel housing. I plumbed the oil temp into that line.
I believe I am reading oil temperature coming out of the engine. If your oil
is going in at 215-220 , I wonder what it is coming out at? It appears I
need to change the location of the oil temp sensor. I definitely want to try
the stiffer spring. Brian said he had one so I asked him to contact me.

I like the idea of splitting the cold air. Do you have any pictures of your
plenum and how you blocked off the base of the cylinders?

Thanks for sending the PZL drawings.

Grover

Grover,

You still haven't said where you are measuring the oil temp. As PZL memo
states, you
should be measuring it at point 7.1, just before the oil return to the
engine.  I modified my
plenum by splitting it in two and sealing the base of the cylinders. Now, in
Florida's heat,
I can take of and climb to 5000 ft with CHT's remaining below 390 F. and oil
temps hovering
between 215 and 220 F. Attached is a PZL bulletin of what Brian is saying.

The franklin engine I have in my 173LW  is running high oil temp, 245+.
Having read recent posts, I am planning to install a larger oil cooler with
a vernatherm. I would appreciate comments from those who have done this. Is
there a modification necessary for the factory oil bypass valve?
