Just recieved the trial casting of my bolt on breather adaptor. This was made to use on my valve covers but can be used on just about anything. The bolt on adaptor allows you to be able to fill with oil or add a PCV. It accepts a 1.25" push in grommet and any push in breather you want.
They are not on my website as of yet. Need to make a jig for machining.
