Try to imagine the friction between metal parts at 6000rpm! To reduce this friction and to make sure that there is enough lubrication at any place and application the oil flow is of highest importance. All small gaskets in the oil circuit makes sure that the oil can flow internally without any pressure decrease and helps to control oil pressure and flow. Of course our main goal is that these gaskets seal all parts of the oil circuit reliably to avoid any oil leakage to the outside. High tech requirements need to meet expectations to take care for our environment. Make sure that your engine doesn´t lose oil, and rely on Elring gaskets.
