The schematics for the hoses is messy i thot id make sure and ask u guys.

There is a 1/4" or 5/16" hose leading from the oil tank to the cam cover on your engine, yes. It serves as a pressure balancer between the engine and tank. You should find a fitting for it near the main engine breather hose fitting. If the popped off, check the breather hose to see if it's pinched or blocked anywhere.
