It can be the raise or lower poppet in the reel lift valve leaking. The reel lift valve is used to control header speed when corn head is installed. I would highly doubt the poppets in the reel lift valve. The approx. 500psi relief valve that is in the line right next to where you hook up the small hydralic coupling is more than likely the problem. Replace the relief valve and you should be back on track. We had some of these leak on early models and the new valve is improved.
