Crowsbeak here are the pictures of the Time Sert repair that you requested. Basically done in four steps:
Drill out existing bolt.
Use countersink attachment in kit.
Thread hole for Time Sert
Thread in Time Sert with their special tool provided in kit.
Bill W, I agree with you regarding not using this type of repair for a cylinder head. I tried the brand below in the picture for a 51 Johnson 10HP and experienced the same problem that you had with the threaded portion coming out with the plug. Ended up just getting a new cylinder head.
It was not made by the Time Sert company so I don’t have any experience if they have a kit that would work. I do believe however that for mangled bolt the Time Sert repair is the way to go.
