I have done that and the problem has gone away. Thanks for the suggestion.

I cannot tell the difference between a bad one and a good one so I was wondering what the actual failure mechanism was. I guess no one really knows. I sure cannot tell from looking at the compensator. I but the bad one in a vise and compressed it and it held pressure quite just like the new one did.

Oh well - probably never really know why.
