Jaloneo and loss of power

Hello everyone ......
Indeed the problem was the packaging of the cylinder head or packaging of the butt box they call, it was burned between cylinders 1 and 2, there was a loss of compression with a symptomatology equal to a coil or injectors or spark plugs or high damaged cables.
They had placed a poor quality packaging before and the car had never been overheated therefore it was never thought to be this problem, it was detected by measuring the compression of each cylinder. The packaging was changed and the valves were calibrated and ready, fortunately it was not needed to rectify the cylinder head.
