In reading your original description of when the bubbles appeared it got me wondering about how you went about performing your leakdown test. Did you use the same amount of air pressure at TDC and BDC? It's possible if the pressure was not the same (higher at BDC) the source of the bubbles may not be a crack but else where such as the head or gasket and just happened to take a higher pressure to show itself. Also just curious how you locked the motor at TDC?

Thanks,
