The owner of this Porsche 911 came to see us after a recommendation. The previous garage had stripped down the engine and were unable to take on the task required.
As the engine was already stripped down we were able to immediately inspect the cylinder walls and determine the issue. The cylinder walls on the naturally aspirated Porsche engines are Nickel Sealed Aluminium and are known to suffer from cylinder pick-up. This is where as the piston is moving up and down inside the cylinder it makes enough contact to gradually strip away this Nickel Seal, leading to loss of compression.
After we spoke to the customer it was decided that to replace the cylinder block it would be worthwhile in fitting the existing cylinder block with brand new Steel Liners. This would ensure that in the future this enginer would never suffer the same issue.
