2005-2007 ford focus 2.0 knock

Hey guys thought I’d share some common issues with you.on 05-07/focus 2.0 they have a knocking sounds on these when cold.these are known for the intake manifold runners to go out.to diag the noise pull the vaccum hose off of the small intake manifold hose in between cylinders 2,3 you should hear the noise disappear while engines running.there’s no rebuild kit.replace whole intake manifold.really easy intake manifold its about 200 I want to say.have a good one guys
