Broken Valve Spring

[splenderleith]

I was unsuccessful in removing the head last night. I believe the air from the compression is plenty to break the seal, but the intake side seems to have a slightly weaker bond, which leads to a gap on the intake side. It seems that the air is then able to escape before it breaks the exhaust side loose.

What I think I may try this evening is to hook up the compressed air and pressurize the first cylinder to see if I can get enough space to get some plastic shims in. I believe if I can break the head gasket on the exhaust side free, I can probably pull it off.

If that fails, I will probably have to find a way to remove the studs. I think that will involve some thin jam nuts, with the same thread as the studs.

I will report back after I try option 1.
