Brian's rule of thumb is in this thread, looks like your TDC marks are not in alignment:

I would change it. It's definitely stretched a bit so needs doing, plus it will take out one possible cause of the rattles. It's a more daunting task to think about than to actually do! Just be methodical, and there's plenty of instruction on here if you're unsure of anything.
Good luck,
Simon.
