I apologize for my endorsement of CAP I went back and read all the posts and admit I was unaware of this problem. I hadn't used the products until 2009 to the present and fortunately haven't had problems. Hopefully the QC was improved on the parts I bought. Again I'm sorry. As old as I am I'm still learning. 75Sport
