Vince -- I AGREE 100% you will see the oil temp drop about 20 d and the
press increase as Billy sez.Mineral oil is the ONLY thing for break-in.I
would highly recomend AERO-SHELL 80 for our climate now.Let engine warm up
till ya have at least 100F showing on the oil temp,then do your engine
run-up,less than that you chance you stand a good chance of galling the cam.
I think Lyc recomends 140 on the oil temp fer T.O. to prevent this.If ya
have any ?????? ya got my ph # ,Bubba

Vince, I think that you might see a 20 psi increase in oil pressure by
using a straight grade mineral oil, such as Aeroshell w-100 ( 50 wt. )
or W-80 which
is 40 wt oil. Don't know what your climate is going to be for the winter
but I would'nt recommend a multi visc oil for break in. Didn't know they
made a multi visc. in mineral oil.?? I think 50 PSI is too low for
cruise conditions.
I'll bet your idle oil pressure ois also very low. billy 026
Billy and others,
Thanks for the advice and comments. I think I've got a handle on it
now.
I had checked the guage against a known guage and even checked the
ground connection at the sender. No problems there.
The Sacramento Sky Ranch website and the Lycoming tech rep tell me that
Lyc. makes 4 different pressure relief springs. Different lengths and
wire diameters for CS or fixed pitch applications.
Lyc. tells me that we CS 540's need the white one, p/n LW 11713. It
will be here today. Lyc says that adding washers will help, but it's
better to simply get the proper spring.
I'll let you know how it works out.
It would be nice if Lyc. could put more useful info like this in their
OH manuals!!! There isn't one freaking word in the OH manual about how
to set the oil pressure. The parts manual lists the 4 different
springs.... but it also is silent on how to determine which one to use.
I guess you're just supposed to know it. WTF? Well, at least Lyc. has
a tech support number, 1-800-258-3279.
Thanks for the info! I think I'm on to it now. I'm also looking for
some Aeroshell straight wt mineral oil to replace the other.
Vince

Hi Vince,
Looks like you have probably found the source of your low oil psi. Good
news.
I have my ECI "Break-In Instructions" manual before me and wanted to give
you all a quote from it concerning break in oils:
"Phillips SAE 20W-50 multiviscosity oil provides quick lubrication for
improved start-up with the SAE 20W low temperature viscosity. All multi
grade oils lubricate three times faster than straight weight, yet its full
bodied SAE 50 viscosity will completley protect the engine at high
temperatures and operational loads. The ashless dispersant (AD) in this oil
keeps your engine's lubrication system free from oil related contaminants.
The dispersant additive further enhances the system by suspending
contaminants and operational wear metals in solution rather than allowing
them to settle to the bottom of your crankcase forming harmful engine
sludge. Finally this 100% mineral product will enhance the mating of all the
parts invovled in systems requiring operational wear-in."
I purchased this oil for breaking in my engine.
Your Fellow Aviation Enthhusiast,
Ned
