Modification Required
These look good online, so went ahead and ordered. Didn't want to clean my old original valve covers off 2009 Expedition XLT 4x4 5.4 3V. Thought red color looks great. OK, got'em. Upon opening, the LH side cover had PCV tube pushed inward, looked at it, it was glued to the cover wit RTV on the underside, cmon, really? OEM Ford had a secure fitting, so when you install the PCV hose from outside and push on the pipe it stays in place. OK, got a JBWeld epoxy kit out, glued the pipe from underside the cover. Feels rock solid now, but hope that JBWeld epoxy can withstand engine oil and not fail. The epoxy can handle up to 550 degrees F, so that shouldn't be an issue, but not sure about oil. Felt like a small detour, so I thought, ok, no big deal. Then I am looking at the valve cover bolts that came with this kit, they are 1/2 shorter than OEM. Those are going to trash. Valve cover gaskets and the bolt gaskets that came with the kit are inferior grade, luckily I already had FelPro set on han

Use the right gaskets and these are awesome!
They fit well and work excellent when coupled with the ford gaskets! The ones supplied are ok, but figment issues.

Are these Dorman or Ford?

Does replacing a valve cover set eliminates knocking noises?
There could be multiple reasons why you're having this particular problem. We suggest taking your vehicle to a nearby reputable shop to identify the cause. Once you know the cause, we'll be happy to see if we carry the parts and how-to videos needed for your repair.
