Yeah, thats been suggested. There are no signs of bulding or venting.

I took one of them off (they are OST brand) and checked it with my ESR
meter. It had ESR of 0.02 so prob stll good and was pretty close to

I know that to be sure I really need to test them all, Not sure if
this would cause my symptom tho?
