Inquiry (采购产品): 2001 Audi S4-Rear Main Seal This engine has been modified for greater horsepower output at turbo boost. Rear main seal leaks. Replacement OEM seal is a double-lip Radial shaft seal of bronze with rubber-infused outer circumference, no seal spring. Still leaks. Am searching for advice/guidance for a custom Rear Main Seal to factory configurations/materials but with a retaining spring (energizer?) added for additional strength. Pounds per inch pressure, unknown. Temp. rating for +300F? Have stock seal and can send overnight for RFQ. But would like a conversation to learn more.
