i bought this motor last week,got a good deal on it,but it needed new cylinder head gaskets i put them in a couple of days ago,and i have a small leak,the leak i am talking about is about 1-2 drops ,I have been watching it ,it's not on the boat yet it's on a motor stand,when i start it about 30 seconds later i get one small drop of water between the head a gasket,then 30 seconds later another drop then it stops,but i have only run the motor for about 3 minutes,i put the gasket on dry,as i was told to do,my questions is do i need to fix this and how ,like a gaskets silicone or something and will i have to buy another gasket thanks
