The cylinderhead showed some leakage around the valves when I tested it with petrol. One good reason to take the valves out and regrind them. Tonight's job: disassemble the cylinderhead. Say hello to my new tool, the valve spring compressor.
This tool permits to compress the valve spring. Then you get access to the cotters and can take them out. Release the spring and the valve spring retainer comes off. The valves come out, some by themselves, some need a little persuasion.
The valves should not mix up, cardboard helps to keep them sorted. Unfortunately, one copper insert came out with its valve. Tapping it back in didn't work.
This leaves me with two more problems: #1 getting an insert off the right size and #2 find the right valve stem seals. Those in the seal kit (left) aren't the same as in my engine.
And one more to prepare a sleepless night, how about this little crack? Is this serious? I will further investigate with some specialist friends and decide what to do.
Cheers.
Cylinder head cracking can even be caused by localized hot spots within the engine, that typically represent a failure in some portion of the cooling system.
