hello everyone.

i own a 1985 yamaha tri-z red & black. why would it be blowing a milky colored oil out of the oil fill plug? and it is blowing it out of a hose on the bottom of it too?

Youve got water in your crank. If you were not driving through water, it came from your cooling system, and the impeller shaft seal probably needs replaced.
