I opened my hood the other day and the rings that are on the case over the engine have broken off. Has this happened to anyone else? And what do you think the cause could be? Just wondering if something would be going wrong under the hood for that to happen.

Thanks for any help

I had it happened to me during maintenance, of course the mechanic denied it. I basically glued it back on and had no more issues for the last 2 yrs

mine are long gone
