[QUOTE="JEEPSTER401, post: 1548826, member: 3946"] The only thing that doesn’t make sense if it were cups is that I don’t see fuel in the coolant and the block test isn’t changing colors. So if it were cups one would have to have a crack from the bottom part in the combustion chamber up into the water jacket. So in theory I should at least show gasses in the coolant. You would think that would affect the way the cylinder/s with the effected cups would run. This thing runs great. If the bubbles aren’t combustion gasses I have no idea where they would come from. I can’t see it pulling outside air in under an area of vacuum to built that kind of pressure in the cooling system. When I say it bubbles in the cooling system it is excessive, like 20 bubbles a second. It is also strange that it hold a pressure test for hours without dropping pressure. [/QUOTE]
