I am leaking coolant or water from the hose on top of radiator where it connects to the engine (by what i think is the intake manifold?). I'm thinking its a seal that needs to be replaced but don't know which seal I need to order. I have a picture but this is my first time on here so I'm not sure how to upload it. also i just cleaned out the pcv system replacing a cracked hose, a very clogged flame trap, and cleaning out the breather box. not sure if that's systems clog would affect my current problem or be signs of something more serious
