During investigation of the cooling problems this car was experiencing, we removed the side plates to inspect the waterways and the visible areas appeared free. Using our bore-scope we were able to see further into the hidden areas where it became apparent that there was a great deal of corrosion and debris blocking the water circulation around the push rod side of the cylinder block.
This has all been cleaned out and new copper tubes inserted. Raymond is now lapping in the valves before putting the engine back together.
