Yeah, they pressurize each cylinder and let it set for a few minutes and watch for bubbles in the surge tank.

That does not sound good. What does the exhaust smell like?

Do you mean that you don't know what coolant smells like? Open the surge tank and stick your nose in there and take a wif. It has a very distinctive smell. Now go smell the exhaust.
