The wastewater is worse than the car

Thinking it was just an electrical glitch with the cruise actuator, I started it back up and it revved to 5k in neutral under no load. Killed engine immediately, then tried again and it did it again and I killed it immediately, but not before it revved to 5k. I crapped in my pants twice. Turns out the two bolts holding the front accelerator linkage plate to the valve cover vibrated loose enabling that part of the linkage to get loose and bind and hold wide open. I had just done a valve adjustment, and merely snugged those bolts. You can bet I torqued them down hard after seeing that. I didn't torque them down hard to begin with because I'm always worried about overtorquing things, especially when it comes to steel bolts in aluminum threads.
My question is thus:
1) how much damage have I done to my car

Car runs fine with no suspect knocking noises, shifts fine- but there is a psychological element that makes me think I hear little subtleties that I haven't heard before. My mind will mess with me like that at times like this. I understand that revving under no load while cold is very bad, but while at operating temp??? The car has been accidentally revved like that 3 times now while in my ownership. Had to lean on the brakes to slow down- but didn't smell anything burning when I got the car stopped. All systems seem nominal. I'm worried a rod bearing or something like that has had its life drastically shortened by this incident, or my transmission has been damaged. Anybody???
Hopefully you can put my mind at ease
Got home from vacation last night to find my kitchen full of the upstairs neighbors wastewater
My goodness what a week I'm having
I think your car is fine. It is not like you are revving to 5K under no load every day. I think a few isolated incidences like this one should cause no undue wear on the motor, especially if it is well maintained. Unfortunately the only way to check a rod bearing is to pull the engine apart. Maybe an oil analysis will tell you if you have a more than acceptable amount of bearing material in the oil.

I hope the wastewater came from the neighbor's kitchen and not their bathroom.
