I have a question for anyone/everyone. As I was putting charger/intercooler assembly back on and tightening up, I noticed a hole that baffles me. You have your port holes that the charger/intake matches up to. Nice machined surface, put your gasket on and mate your charger. The driver side has an extra hole that is not covered by gasket or mated to anything (that I know of). What is it for? pressure/steam vent of some kind? Does it go anywhere particular. I am really curious about this and want to make sure I haven't forgotten some component or key application. Cheers
