The valve is actually located inside a small hole that feeds oil to the
head of the engine. It just screws into this hole with an 8mm triple
square tool. It is a check valve that is supposed to keep oil from
draining back from the cylinder head. Here is a link that has a picture of
it if you scroll down. They are calling it an oil retaining valve.
