Antifreeze for our Rockets


I already put some permatex around the head of the bolt but I cant see it leaking from there.
Im getting a few drops congealing under the water pump. I had the hose off to do a coolant change but cant see any tell tale dribbles coming from there either.
Im going to take the belly pan off again and try to see the drops forming.
 
Yeah. A little fuel change here. A little compression change there. Switch the direct injection for throttle bodies. Add a few spark plugs and voila - R3 engine.

With this much torque, it's not easy to distinguish from a Yanmar.
