Well when I run my car hard I hear hissing and sizzling where the turbo water line adapter is. I have the SS lines for my turbo water lines. I was wondering if this would cause my car to overheat and lose coolant. I recently did MHG / ARP. There is not a single coolant leek elsewhere, no oil mixing with coolant/ milky coolant. I have straight tap water in the car atm so the water is a bit rusty. Besides that, the car pulls hard, no smoking or anything. Please feel free to chime in and thank you for all the replies.
