Henry, your pilot is doing some not so legal things anyhow, why would he
obey the law if he's breaking the law? What's one more little broken law
between friends?

If you want a real provable engine problem, have them obtain a lead fouled
spark plug, land and replace the good one with the bad one. Instant
engine problem and since plugs are changed all the time anyhow, it's not
going to be unusual to find the tool marks on it, he could even make a log
entry stating he cleaned the plugs to explain the markings...
