Ok I noticed today while trying to find the location of an oil leak around the crank case that I have a hose without a hose clamp. I can tell that it is missing a clamp because I can see the indentation on the hose from a clamp that used to be there. Also the fitting the hose connects to is loose where it enters the cylinder head. So according to the parts manual it is on page # 26 and is part # 23 and is called simply "union"? What does this do? Should I be concerned that it is loose in the metal cylinder head and has no hose clamp in place? I am assuming it is not good but what would it cause by being loose? Any help would be great. Sorry if unclear not sure how else to describe it.
