adjusting valves/ stud mount?? PKRWUD? Anyone??

Thanks for the slick 50 tip. I do a lot of around town driving. And my car rarely sees the freeway, really. If it does it's usually just for a few miles at most. Plus, my car did sit for a while (a couple of years) when I was having problems getting it smogged. But it's been back on the road now for a little over a year. Sounds like it's time to change my oil again. Thanks again.
