P&W Radial: Breeding cylinders overnight!

Don't you just HATE it when you park your DH Beaver up for the night, and then wake up next morning to find that your lovely old 450 HP. Pratt and Whitney R-985 Wasp Junior, 9 cylinder radial engine has sprouted an extra cylinder!
(There aren't too many single bank,8 cylinder, Pratt and Whitney radials out there...trust me..)...!
LOL...!
The correct arrangement....
...!

...and a close-up...

..my two Beavers have been up to naughty things over-night.... :-[...?

...and a close-up...an extra cylinder...!!

This is what it should look like, (similar, R-1820).....

Single bank 3's, 5's, 7's and 9's are OK...!
Single bank 8's are rare, if actually, non-existant...!
LOL...LOL...LOL...!
Cheers...
