Mechanic's Assistant: Where exactly do you think the noise is coming from? And how long has this been going on?

Under the hood left side

Mechanic's Assistant: Are you fixing your Seville yourself? What have you tried so far?

I have taken it to three shops who road tested it and .... no solution also the Cadillac dealer checked it for two days.....same answer !

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?
