The chip is not an issue, if it does not go into the water jacket. Maybe, see is you can get a dremel tool in there and smooth out any sharp edges on it to stop any crack formations.
ok, thanks, i do have a dremel that is small, what tip should i use to smooth it down sand paper i have the 12 grits. and also should i just work the top of it and not the front of it right.
