Can't see any clear evidence of anything, although the water ports in front may have been wetter. There is no hole in the block that I can see but I also cannot see whether I managed to damage Cylinder #1 with a too-long and overtorqued bolt, as was suggested at some point above. Is there a way to check for this?
It seems I only have a set of stamped metal intake gaskets I got by mistake a while back. Do I remember correctly that I should not use these on an aluminum intake manifold?
