How to tell if I need to replace valves in motor?
my car runs good but has a little skip, someone said oil might be passing and getting onto spark plugs causing the skip.

Normally poor performance or a compression test will tell you if your valves are bad or not the skip cold be a bad plug/wire etc. Normally not a valve to do that.
