Borescope helps to check a car engine

I found an article about borescope use to check engine. It illustrates how a borescope can be used.

"If there's evidence of coolant loss, ask the customer to leave the vehicle overnight. Safely vent the cooling system pressure at the pressure cap, then install a cooling system pressure tester. Apply pressure to the cooling system with the tester, then allow the engine to cool down. If the pressure tester appears to be losing pressure as the engine cools, keep adding it with the pressure tester. When the engine has cooled completely, begin looking for coolant leaks.
Remove the spark plug first. If you're lucky and the leak is large enough, yon may be able to see coolant leaking into the combustion chamber. It may even give you a shower when the ping is removed. A borescope would be handy here, as it would allow you to identify the precise source of the leak by looking through the spark plug hole. Potential leak sites could include a cracked cylinder head or a blown head gasket. You'll be able to see the coolant leak dripping from the head crack or gasket fault with the borescope".
