Hi there,

This is sounding like a burnt exhaust valve in the engine, that is engine compression is leaking past the burnt valve, but I feel the price is a very bit high, I would consider getting a few quote on fitting a change over cylinder head, this may be a cheaper option for you that will still address all the original problems.
