    Talon is talking about the piece or pieces below your powerhead. The cooling systems can be quite complex if someone has messed with it. Obviously someone has since therms are missing

    Did you try removing poppet valve and putting the cover back on to see if water comes out? and is there a spring in the valve.

    I'm not sure if it would create enough pressure to open poppet. I just reread this entire post. In post #1 you said you had 35 psi @3000 rpms and in post#13 you had 20 psi @2000-3000 rpms. Two totally different situations. Ideally you want 20-30 at WOT and 5-8 at idle. If you have a good psi gauge and your poppet is working properly, you should see pressure drop at around 2000 rpms when poppet opens (if my memory serves me right). Have you pulled poppet and made sure all parts are there?
