Good to hear. Sounds like you nailed it!!!

That's an interesting and pretty rare issue, and definitely brings up a point for people changing their own plugs: If one had pulled the plug boots, and blindly shoved a plug socket down the recess, and removed the plug all that water would have just dumped itself into the cylinder with potentially nasty results.

So even if the plug boots come out dry, grab a flashlight and do a visual in the spark plug wells to ensure there is no water or other debris down there. A good blast of compressed air would definitely help clear out any foreign matter before removing the plugs.

 

Yes spark plug changing 101! Ensure there's no water or debris that can fall into the cylinder and cause damage!
Some manufacturers used to suggest loosen the spark plug half a turn and turn the engine over to let the compression blow the dust out!
This was a common problem on Dodge 225 slant sixes, Mopar Hemis, Toyota 8RC four cylinders of the 70's
