<VV> Flying Sparkplug

[Larry Forman]

Yes, flying sparkplugs are one of those rare options.    I have had one 
or two come out also.   While helicoils might work fine, I prefer to use 
TimeSerts.   These are installed so that the inner lower wall of the 
insert is thicker and after installation tends to lock itself in place 
better than helicoils.    The inserts are more expensive at around $3 or 
so and the installation tool kit is more expensive at something over 
$50-60.   However, I still like them.   I also use them to replace 
stripped out head stud threads and they work well PROVIDED you run a tap 
over the head stud threads so they go into the TimeSert without 
binding.   If you do not do that you will tear out the TimeSert from the 
block after installation, which trashes the entire block.

Don't ask!

Last Monday night coming home, engine running smooth and quiet, suddenly sounded like an M-80 firecracker going off in the engine bay followed by a horrible racket sounding like a lost muffler or worse.  Arriving home in the garage, light revealed that the number one spark plug had departed it's hole and wound up in the battery tray.  A helicoil later and the plug was reinstalled and the sparkplug wire which had been caught up in the fan belt, replaced.  I can't for the life of me figure how that plug came loose.  Its been in there for at least three years.  Now suddenly it goes flying out!  Question:  Does the Vair have a reputation for spitting out sparkplugs spontaneously?  In the more than 55 years of driving various cars, this is the first time I have encountered flying sparkplugs from any of them.   With the plug back in its place, the engine is back to running smoothly, as if nothing untoward had ever happened.  Anyone have experience with this type problem?
