Look for cracks or when they have become sufficiently stiff that the vibration bothers you. My 360 made it 18 years before cracks. I just replaced them. It is much smoother now. Should have done it years ago.

I have had Barry mount high temp vibration isolators mounted on my TSIO550. for almost ten years and 900 hours
My question is does anyone know how often the isolators should be changed?
Thank you,
