I am not the owner of the car I have been asked to rebuild the engine for the owner. The cylinder block has been rebuild two times. When the owner brought the car to me for diag. Cylinders 2,3,6,7 were not firing. I also noticed at high rpm it had a crank rumble. Long story short what I have found so far. Block had 7 cracks. Cylinders on 2,3,6,7 had turned blue from heat. Water jacket had a jury rigged plate, the holes did not line up with the space between the cylinders. The plate covered about 1/8" of the water pump discharge area. The plate was 3/16" from sealing the front area just behind the water pump discharge. Water pump impeller has been rebuilt but the impeller was 3/8" from the block. The car has a working shutter system, it also had a thermostat. It does have an after market temp gauge mounted under the dash. It will be removed tonight and checked for accuracy.
I have my own theory on the above mentioned but would like to have any input regarding the above topics.
Owner stated it has never been hot damage shows other wise.
