So I just got my 2001 Lightning back from the shop for some regular maintenance and the mechanic told me that my Oil Pan gasket as well as the gasket for one of the valves was leaking.

I'm a little pissed because I just had this oil pan gasket replaced at 34k miles and it wasn't cheap. Now i'm at 50k and they are telling me that it is leaking again. Could this be a sign of something more serious? I haven't notcied the truck leaking any oil on my garage floor so hopefully its nothing to worry about.

The valve gasket leaking is new to me, should I be concerned or is this just my truck starting to show its age?

Any advice would be appreciated.
