Seal Up Your Cummins ISB 6.7L, 5.9L, or 4.5L with a Complete Upper Gasket Set
Is your Cummins ISB 6.7L, 5.9L, or 4.5L overheating, weeping oil around the valve cover, or showing discolored coolant in the reservoir? A failing upper engine gasket is one of the more common reasons an ISB starts leaking or losing compression at the top end, and once one seal starts to go, the rest are usually not far behind, since they are often the same age and have been through the same heat cycles. HHP’s new 4955229 upper gasket set replaces every major seal on the top of the engine in a single purchase, so you are not chasing down individual gaskets one leak at a time and paying for shipping and labor on each separate repair.
Why Replace the Whole Upper Gasket Set Instead of One Seal at a Time
Engine seals take constant heat cycling, vibration, and exposure to oil and coolant, and over time that wears down the materials holding a tight seal. Replacing a single gasket when others nearby are the same age and condition often means doing the job again within a year or two. This complete upper gasket set lets you replace everything at once during a head gasket job, valve cover repair, or turbocharger service, so the engine goes back together with fresh seals throughout the top end rather than a patchwork of old and new.
What’s Included in the 4955229 Upper Gasket Set
The 4955229 set is manufactured in an ISO 9001:2015 certified facility and built with hard wearing materials designed to handle the heat and vibration of daily highway use. It includes a cylinder head gasket, valve cover gasket, rocker lever housing gasket, intake manifold cover gasket, accessory drive cover gasket, oil drain gasket, six exhaust manifold gaskets, a turbocharger gasket, two turbocharger oil drain gaskets, six injector seals, a thermostat seal, and a wide range of O-ring and sealing washer sizes used throughout the upper engine.
