--> TeamGrumman-List message posted by: "Steven Jackson" <steven.jackson14@adelphia.net>
TG,
I don't know if I even spelled it right, but my engine is an O-320B2B.
During the engine teardown that's on-going, the nut was pulled off the
accessory case and there was nothing behind the nut. No ball in the
sleeve--nothing. Is this proper? How does the engine know when to send oil
to the cooler without this, or is it designed to always go to the cooler?
My oil temps always seemed to take a while to warm up during run up--could
this have been the culprit?

TG,
For anyone in the Southern Cali area, any recommendations for a shop to
powder coat the engine mount?

.... my O-320 parts manual says this is OK if you have a
"Valve Assy, temp. control, oil cooler bypass" (aka Vernatherm) in the
system. This Vernatherm would be in the end of the oil screen housing or
vertical, from the bottom, in the oil filter support casting.
I believe the Oil Screen is the most common on the O-320, but
you could have either...
If you don't have a Vernatherm, then you need
69436 SPRING, Oil cooler bypass
62415 PLUNGER, Oil cooler bypass
These go below the plug (I think you called it a nut) that has
a 5/8 thread and screws down vertically from the top on the rear of the
accessory housing... This same hole is also one (of several) take off
points for oil to the oil cooler.
hope this helps ... gil A
PS you definitely need the Lycoming Parts Catalog for this task.
It's worth it just for the pictures...:
)
I'm quoting from mine that covers the -A and -E models, but a -B models are
a 160 HP version of the -A models, and should be almost identical, except
for the cylinders (nitrided) and pistons (higher compression).
