Hello, I know the instructions for the Intake Valve and Combustion Cleaner Kit say to let it sit for 15-30 minutes, but what's the maximum time it can soak in on a fully warmed engine? Is it safe to leave it sitting overnight, or is this product designed to only work with a warm engine?

Warm. You want the engine to stay at least warm so that the chemical keeps the carbon "lifted." If you let it cool off, you run the risk of the carbon redepositing.
