I put 2 spoonful of MMO into each cylinders to soak the rings last night as the head was removed. I found the oil is drained into the oil pan in 2 cylinders, the other 4 still has oil in there. I have problem with the rings on the 2 cyl? I also reached down the cylinders wall and swipe it with my hand. I found cyl two has 2 scratches.

Is my engine block shot? Shall I put the head together and hope for the best. The engine was running and did not smoke. The problem is shaky idle and smoke coming of the 1mm vent hole on the left back valve cover. Also I had water in the cylinders so the HG is definitely shot.

Any opinions?
