Conservation/ Maintenance History
Cylinder 1 Low Compression

An attempt was made to remove the exhaust valve cage from No 1 cylinder. This was found to be seized and eventually broke. The cage was collapsed in-situ and has been now been replaced. Compression remains low on No 1 and 2 cylinders and the engine will require a full strip although currently running.
