Shock loading an engine is serious and expensive.
It means completely stripping the engine and checking for damage in the crankshaft, prop governor, magnetos, gear box etc..
Of course when the engine is stripped the other non related shock items may have to replaced due to wear or ADs.
Crankshafts and crankcases are expensive if they need to replaced because there is no core value for them. You're probably aware that these items get used over and over again even when an engine is 0 timed.
Think thousands of £'s. Best not to try it!
