Thanks AutoZen.

I sometimes get some flak for the sort of contrarian nature of my comments.
People often react from a very narrow point of view. This thread is a good example.

The guy who came back with comments to previous posters is only thinking about the specific problem. I tend to view threads as topics for discussion.
One of the reasons, in my case, is that I am not a professional mechanic. I can only offer up my view of how to approach the problem in general. I really value and enjoy the responses from people in the business who actually see these problems in real life.

I do problem solving for a living. Consulting with clients in my industry about how to run improve operational efficiency. Of course, when the inter-action is live two way communication it's easier to help them through problem identification and suggest solutions. These forums are largely one way with long delays. They are also, by definition, have members from a wide variety of backgrounds, educational levels, and occupations. That makes for some contention, frustration, and hopefully some reflection.
