I am in the process of awakening a ´68 2000 TC that´s been off the road since 1982. As the compression ratio was almost nil on a two cylinders, I removed the cylinder head to have a peep. Before doing that, the valve clearances were checked and found to be zero on number 3 and just over nothing on cylinder number 2. I had expected burned exhaust valves, but to my surprise both valves and seats look ok - no cracks - though the valve stem on exhaust number 3 has a lot of carbon deposits, which may well be the reason for the lost compression. But SOMETHING nasty has happened, as can be seen from the photos - but what? Am pretty certain that this is the first time the head´s been off since the seventies, as witness the presence of Jubilee clips and state of hoses etcetera. Any suggestion on what's entered the cylinder and caused these marks would be appreciated!
