Conversation: dirty oil
Subject: dirty oil

....
... In a previous Lyc
TIO-540-S1AD, I had bad exhaust valve guides. Hot gases blew through
the
sloppy guides and burned oil in the rocker box. There was lots of
black
stuff in the rocker box, and oil and suspended black stuff drains from
there back into the engine.

For pix, see http://aviation.sprevost.net/Engine-Photos/Cyl-Nr-1.jpg
and

http://aviation.sprevost.net/Engine-Photos/Cyl-Nr-2.jpg for a bad one
and
a
good one.


Outstanding example photos Stan. Thanks...
