Hi Lovel,
Thanks for your info.
I am dealing with a water leak on mine. I guess the waterpump is the culprit, but may be the bolt you are mention as well.
Do you have some pictures of your engine showing the "V" and the rear and right bottom end? There is a square hole in the casting right below the hose-nipple on the rear right end. Is this hole only a blind? Is there any drain channel from the "V" and down on the RH side?
Trying to figure out where this is comming from:
