Believe its built into the plastic valve cover on top, that round cap looking thing with the hose coming off of it, next to the dipstick in that picture.

thank you! That's what I was thinking too, I want to change the valve but the mechanic said we need to change the whole cover on the top we can't change that round cap only is that true? Anyone has done it before here? Thanks.

Not sure havnt done it. I did see some various videos where it shows you can rebuild the valve. Look up the parts for it and see what is orderable.
