Sorry Chris I don't know where it is.

Might be worth doing a search on the forum for "bleed screw" and see what comes up.

The search button is just below your log in name and slightly to the left

 

Its located along the return pipe which comes around the engine on the Air filter box side. Bleed screw is roughly under distributor i think. Towards back maybe, under neat inlet/injection manifold.

I am assuming it is a K-Series

 

Welcome Chris to .ORG, I have just found this thread and moved it into the F/TF section (I am assuming that is what you are asking about?).

Take a look at this page and this page, it's quite involved.
