Federal-Mogul‘s Fel-Pro Gaskets brand has introduced two Fel-Pro PermaTorque MLS multi-layer-steel head gaskets that address a common combustion sealing issue encountered in 6.0L diesel engines. The patent-pending PermaTorque MLS head gaskets are available through Fel-Pro distributors.
Owners of trucks equipped with Powerstroke 6.0L diesel engines have encountered premature head gasket failures and resulting engine damage caused by leakage of combustion gasses into the cooling system, said the company. The engines, originally equipped with multi-layer-steel head gaskets, have been known to experience combustion leakage at as early as 50,000 miles of service under heavy loads.
“These engines generate a great deal of power, heat and combustion pressure and are being run in vehicles seeing heavy use, which can exceed the sealing capabilities of conventional, OE-style MLS head gaskets,” said Jim Daigle, product manager, sealing, Federal-Mogul Motorparts. “Our engineering team invested thousands of hours in designing and testing these new gaskets to ensure that they meet Fel-Pro standards.”
The Fel-Pro PermaTorque MLS head gaskets feature several design enhancements that address combustion leakage and other issues encountered in these existing engines. The gaskets include an embossment design that creates increased spring force—and significantly more robust sealing contact—than conventional gasket designs under extreme loads, according to the manufacturer.
The PermaTorque MLS gaskets also feature a highly controlled thickness of proprietary FKM rubber in all critical sealing areas. Each gasket is engineered to accommodate engine overbore.
