The SB assumes that you have ECI parts.

Does anyone know the thickness of the original (good) Lycoming part?

...and whether it is carbon or stainless steel...

These flat springs hold the pushrod tubes in place. So to check them, remove the valve covers. Broken springs might then fall out but the pieces might be trapped by the one nut holding the spring in place. Either look carefully for cracks in the spring adjacent to the nut or better yet, loosen the nut to see if the spring is broken. This will require that you have replecement sheet metal tabs available for the nut.

Well I've seen non-ECI retainer springs broken, in fact I've broken them myself. There are variations to the studs in the cylinder head casting and thats why if you buy a cylinder gasket kit they will come with different variations of retainer springs.

To be honest it irritates me that a private individual would be pressing the FAA to issue an AD. This would cost a lot of owners a lot of money to comply with, and just increases costs for all of us. It is not a safety of flight issue because even if the pushrod fell out (they won't) the rocker would keep it from falling very far and with only a remote chance of causing damage. All AD's originate from manufacturer service bulletins and I can tell you from experience, particularly on a certified aircraft I own with a recently issued AD, that once the FAA goes to issue an AD they usually throw in some stupid compliance requirements in addition to the SB. In other words getting them involved generally doesn't help much.

I pulled the covers off of my IO-360 after reading this thread and found the retainers were broken. They fell apart when removed. The engine has not yet flown so I feel fortunate to have caught this now.
I can't read every thread, no less every post so it's only luck that leads me to some of them. If we don't use the services (we pay for) of the FAA, how is a person supposed to know he's skating on thin ice with some of these issues? I agree that it would be nice to have a better system.
I'm certainly grateful (again) to have this forum!

Default Original Lycoming clip

First generation OEM Lycoming clip is .032", second generation is .040". ECI clip subject to the bulletin is .032" and you can't tell an original OEM clip from an ECI (no part marking). How's that gonna work when you can't tell one from the other?

I called ECI and they were very helpful. They said they would be sending new retainers, lock tabs and gaskets the same day. Kudos.
FYI: the engine was assembled by AeroSport in 2010 and they did use one heavy washer behind each of the retainers. So, what do you guys think? Should I reassemble with the washers as delivered from the builder or without per the manual or use the fit each part with "little pressure" method?

NO SIR

I believe the picture you linked to is generic for the narrow deck cylinders.

Note the end shape of the pushrod tubes - machined not formed

Note the TWO springs in your diagram.

Note the square shape of those springs.

It's not for the much more common wide deck Lycomings....

This is a more applicable picture -
