My Townace was getting work done over the winter- needed to have the fuel injection pump rebuilt (learned that a tooth sheared on a gear within the governor) and also decided to replace the timing belt... So the van sat for a few months at the mechanics during the whole ordeal. Earlier this week, everything was looking good for the Townie to hit the road again, when the mechanic called and informed me that it had gotten worse...
Apparently while the engine sat, partly dissembled, moisture caused a valve to stick and when they cranked the engine, the stuck valve jammed the camshaft, caused it to shear, and also bent the valve or valves and possibly damaging the head.
They consulted local engine specialist and it was recommend that I replace the entire head cylinder assembly due to how they manufacture these components. I guess everything is ceramic-casted together, then machined to the proper tolerances, so these components (head, valves, and camshaft) are created as a machined set and thus each component cannot be individually sourced and replaced? Is this true?
Did my mechanic accidentally screw me? I was told by someone else, he should have manually cranked the engine first before cold starting it...
What are my options here? Has anyone else survived a similar catastrophe? I'm guessing this is a similar issue if a timing belt failed...SaveSave
