The cost of adjusting valves usually includes an oil change since the oil wants to run out with the bottom covers off. You can do this for the price of a gasket set and some sealing nuts if you raise one side of the car at a time and adjust the valves on the high side. And, you can order some silicone VC gaskets and use them over again. It's always a good idea to use new sealing nuts each time to prevent leaks.

That having been said, you could pull of a top cover and check out what's in there, maybe throw a feeler guage in there just to see what's going on. Can't hurt and you might decide to go ahead with it. Get a copy of 101 Projects from our host. You don't need hardly any more tools than what's in your tool kit.
