<VV> Flying Sparkplug

[Joel McGregor]

I've never seen a TimeSert that didn't have a shoulder on it so you can't go too far.  ???
Curious on blown out plugs - do they just blow out due to damaged threads or do they come loose and spin out until there aren't enough threads left to hold them and then blow out, or some of each?
I guess it's not too common.  I've never seen it in any of my 40+ Corvairs or my piles of heads with lots of other issues (mostly bad seats).
...I shouldn't have said that...

When using TimeSerts, be certain to not turn them too far into the head as I have learned from watching that the 'tink' sound of it falling into the combustion chamber is a bad sound - Very bad.
Led to head removal, first of the guy who did it, then the engine.

Not common but, it happened to me, once, some twenty years ago. First and only time while driving 'vairs by 47 years.
