Last year I changed the engine in my boat and I installed an OM 606.962.
The Turbo I mounted then became too big so when the boat is full loaded, it cannot rev up in enough to spin up the turbo.I will now mount a HX 35 turbo instead
I have not been able to measure the exhaust temperature but I think it has been too high because loss of turbo pressure.

The engine could reach max 2800 rpm and the turbo started to build pressure at 3100-3300 rpm.
so it became a slow boat vacation 
I have run the engine like this for about 100 hours 
Before I started to dismantle the engine, I wanted to check the compression and it varied between 6 bar and 31 bar.
When I had disassembled the cylinder head I checked the exhaust valves and all were leaking.
is there anyone here who knows what has happened to them? why do they look like they do?
I also saw that all cylinders except cylinder no. 2 are marked with an X, cylinder no. 2 is marked with an A Why is it like that?
What is recommended that I change now when I have the entire engine dismantle
