How exactly is the engine running?
What makes you think it's on it's way out?
Need a little more info. so I can direct you in the most practical way to move forward on this issue.
low power, rattling noise coming from the cylinder /head when revved. runs very very hot. after a few minutes of running it bogs down. the spark plug looks light brown.
