I can not figure out what hose attaches to the roughly 20mm nipple on the timing cover right above the water pump. I know it has to be oil or ventilation related but for the life of me I can't find it. When I got the car they had the turbo oil return line ran there but I know that's wrong. I can't find a pic of it anywhere that has it hooked up. Any help is greatly appreciated.
