Fel-Pro® Introduces long-awaited solution to chronic sealing issues facing engine Professionals


The 6.0L Power Stroke® diesel engine was used in more than 700,000 Ford Super Duty trucks and Econoline vans manufactured between 2003 and 2010. Many owners of these vehicles experienced head gasket failures and resulting engine damage caused by leakage of combustion gases into the cooling system. Various media reports have attributed these problems to stretched torque-to-yield head bolts and insufficient clamp loads. Regardless of the reasons, 6.0L Power Stroke engines are known to be "tough on head gaskets." Many engine professionals who have utilized OE-style replacement gaskets in their repairs have encountered repeat failures.

Some engine professionals who have installed OE-style gaskets on these engines have encountered repeat failures.


Following thousands of hours of design, materials formulation, prototyping and testing, Federal-Mogul Motorparts has introduced two innovative Fel-Pro® PermaTorque® MLS (multi-layer steel) head gaskets that stand up to the demands of 6.0L Power Stroke engines, providing the long-lasting, trouble-free sealing professionals demand. These gaskets include an advanced new embossment design that creates increased spring force and robust sealing contact under extreme loads. Each gasket also features precisely controlled thicknesses of proprietary FKM rubber in all critical sealing areas. Both gaskets are designed to accommodate overbore. As an additional, exclusive benefit, these PermaTorque MLS gaskets incorporate a patent-pending oversize guide hole for the pushrods, which eliminates premature pushrod wear and oil contamination.
