Well, at least it runs good. A lot of mechanics don't check the timing chain during the valve adjust unless you specifically ask them to. Next time make a point to ask them not only to check it, but to tell you the number of degrees the chain is stretched... it wil always be stretched a little, you need to know how much. 0-3 is fine, 4-5 means you should replace it when convenient, and 6+ means avoid driving the car until it's replaced!
