JE Pro Seal BMW S54 Series 87.5mm .044in Head Gasket jepBM1009-048
1. The JE Pro Seal BMW S54 Series 87.5mm .044in Head Gasket Stepping up to Pro Seal MLS head gaskets from the composite or graphite units now are standard equipment on many factory engines.
2. This trend is being validated by more automakers offering MLS gaskets on select high-performance engines in their lineups.
3. Also, all NASCAR and Pro Stock teams use MLS gaskets as composite fell out of favor and solid copper gaskets were not effective in sealing fluids.
4. An abbreviation for multi-layer steel, MLS gaskets have taken center stage in the shop due to a number of engine-builder-friendly features.
5. Granted, they can be a bit more expensive that conventional gaskets, however, the performance and durability advantages will pay off in the long run.
6. The “JE Pro Seal gaskets differ greatly from OEM gaskets,” said Jeremy Anderson of JE Pistons.
7. “JE Pro Seal gaskets have a proprietary outer layer coating that prevents them from sticking to the deck surfaces.
8. JE gaskets go through a heat treating and tempering process for good.
9. The basic premise of a MLS gasket is sandwiching three or more layers of thin steel that have been embossed in critical sealing areas.
10. The embossments act as “springs” to ensure that there is no leakage of fluids or combustion pressure if the cylinder head moves or expands while the engine is under heavy load.
11. The gaskets can also be coated to improve sealing in “micro” areas between the block, head and gasket.
