Think my engine is going to die :(

Depends on your situation. If you've got a bit of time sure you might as well strip it and see what's going on inside. You could get a used head and cams cheap enough if that's the problem or if you need it for everyday transport and you don't have the time to fix it maybe go down the replacement engine route, they're fairly reasonably priced you might even get one on here.
