Quick question for the brain trust.  I am finishing FWF and was wondering about issues involving securing the EGT  (Dynon metal braid) lines in the same cushioned clamps as the spark plug cables for a clean and tidy installation.



Are they respectively shielded enough that there is no issue or is it better to secure them separately?



Thanks in advance.

Mine are tied together without any issues.

Using the Skyview setup, this is exactly what I did without any issues at 

all. Get a CHT spike every once in a while but that is a connection issue 

and not a routing issue. You will have no issues putting them all together.

Myron,



It sure would seem like the very high voltage to the spark plugs vs.

the very low voltage from the thermocouples would be a bad mix--like

it would bleed over and give the EGT some kind of bizarre reading.

But, I've seen it done on lots of installations and it never seems to

be a problem.  Has anyone seen any oddball EGT readings as a result?

It does make sense from a neatness/weight/convenience/hardware count

perspective to run them all together.

Although running AFS equipment mine are neatly tied together and all readings are rock solid.  Also true of the other planes my dad and I built.    It's a non issue.

I ran mine in a separate clamp attached to the same valve cover screw as the ignition leads.  I did not want to take the chance if an erroneous reading with the egt.  In reality, the egt lines are such low impedance that the chance of it happening is slim.  It was too easy to just use additional adel clamps...

I'm curious what you guys did for the lip of the valve cover by the 

screws.  Did you add washers to lift up the contact area of the clamp to 

clear the lip of the valve cover?

Yes.  Standard practice!

Yep, added washers.

The new LYCOMING engines come with a bag of washers and screws that are longer than the factory installed valve cover screws.  The washers go under the clamps

That is what I do Sean, to ensure the valve cover is secure and to give the adel clamp a flat surface to rest on.

Thanks everyone.  That's what I figured, but wanted to confirm.
