LOL hiding parts from the wife !! Can't you just unplug a spark plug wire and tell her its all necesary?

 

I would but my father in law is a very good, very experienced mechanic... My wife pushes me to ask him for help and on occasion tells him im working on the car and he asks me whats up (both of them trying to help out, not letting me handle it myself)... I can hide it from my wife, but not my father in law....
