This is a big problem on the Ford DOHC engines. You will even find references to it on the Ford Focus forums, and they have an engine cover and no bonnet louvres. Morgan should be providing a solution for this. Caterham supplied a cover for their Ford Duratec engines. It is not perfect but it does help. I used one of these but I had to modify (as in cut) it to clear the supports for the engine coolant pipe that runs above the inlet manifold. If I had known about this before I fitted the throttle bodies I would have replaced the tube with one that runs below the manifold. I also improved the seal to the cam cover by the judicious addition of some self adhesive neoprene.



This is the carbon fibre offering from Caterham but I found one in fibreglass at a much lower price. I think a similar cover was also made by Cosworth.
