If you would have the time and could copy it down I think it would be helpful. To me and others in the future looking for this that would be a big help. Thanks much!
?n number 3 , 9.part has only 1 hole. Coolant flows through this hole. If there is high pressure coolant pump ,maybe it is normal. If normal pressure pump, the gap between part number 9 and 12 is bigger than normal. I think this the problem. Not back side.
