Get yee a manual.Most likely it is simply a <br />leaky water jacket cover.A fairly simple repair<br />though some bolts are hard to reach.

Dagored,<br />I have a buddy's exact same engine torn apart in my garage. He was having the exact same problem, it seems that the engine had a hole blown through the #1 piston. So we had to get the head redone and welded, it is not an easy engine to work on, due to the way it was built. The head and block are all one piece, the entire engine. So we will be putting it back together in about a week or so. His had water coming out around the spark plugs due to the hole pressurizing the water jacket, this all was caused by a rock being stuck in one of the little tubes that took the water out the pee hole.<br /><br />Thanks,<br />Bryan Cox
