2Pcs Aluminum Valve Cover Set With Gasket For 2013-2016 Ford F-150, 2015-2022 Ford Transit-150/250/350, 2015-2017 Ford Expedition & Lincoln Navigator 3.5L V6 EcoBoost

Valve Covers for the Ford and Lincoln 3.5L EcoBoost V6

This is a pair of left and right aluminum valve covers with gaskets, built for the 3.5L V6 EcoBoost engine used in the 2013-2016 Ford F-150, 2015-2022 Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD, and the 2015-2017 Ford Expedition and Lincoln Navigator, cross-referenced to OE numbers BL3Z-6582-H (left) and DL3Z-6582-C (right). If you're seeing an oil leak along the top of the engine or a valve cover that's cracked or warped from heat, this set replaces both covers with new gaskets already included.

Why the F-150, Transit, Expedition, and Navigator Share This Engine

Ford's 3.5L EcoBoost V6 was used across a wide range of the company's trucks, vans, and full-size SUVs during this era, including the F-150, the Transit van lineup, and the Expedition, with the Lincoln Navigator sharing the same engine and much of the underlying platform as the Expedition under its own badge. That shared engine architecture is why one pair of valve covers, cross-referenced to the same OE numbers, fits vehicles across four different nameplates and two brands instead of needing a separate part for each one.

Compatibility

Fits the 2013-2016 Ford F-150, 2015-2022 Ford Transit-150/250/350 and Transit-350 HD, and 2015-2017 Ford Expedition and Lincoln Navigator, all with the 3.5L EcoBoost V6. Because Ford used more than one V6 displacement across these model lines during overlapping years, it's worth confirming your specific vehicle has the 3.5L EcoBoost engine before ordering, particularly by checking the engine code on your door jamb sticker or against your owner's manual.

Signs Your Valve Cover Needs Replacing

A failing valve cover on these EcoBoost engines typically shows up as an oil leak visible along the top or sides of the engine, a burning oil smell from oil dripping onto hot exhaust components, or visible cracking and warping in the cover itself from years of heat cycling. Because the valve cover gasket also seals the coil-on-plug openings on some of these engines, a failing gasket can sometimes show up as a misfire caused by oil contaminating the ignition coils rather than just an external leak.

Why Replace the Complete Cover Rather Than Just the Gasket

While a valve cover leak is sometimes just a hardened or improperly seated gasket, a cover that has already warped from heat or developed a crack won't seal properly even with a brand-new gasket installed on it. Replacing the complete cover with a new gasket included removes that guesswork and ensures the sealing surface is flat and true, rather than spending labor twice if a gasket-only repair doesn't resolve the leak.

Installation Notes

Replacing a valve cover on this engine means removing the engine's plastic cover, disconnecting the ignition coil wiring and any breather or PCV hoses attached to the valve cover, and unbolting the cover in the sequence specified for your engine to avoid warping the new part. Torquing the valve cover bolts to factory spec in the correct pattern is important, since overtightening cast aluminum covers can crack them or damage the sealing surface, undoing the benefit of installing a new part.
