My thermostat housing has corroded and is badly pitted and leaks against the head and inside where the thermostat sits so it constantly leaks water through. What are my options, can it be refaced or are new items available? Also why is there a take off after the thermostat what can/was that one for, mine is blanket off while the first one before the stat still feeds the turbo.
Could the second be used as a return from the turbo so it is cooled before returning to the header tank? I've got a post turbo cooler but I was curious
