Overview

The iABED Industries Billet Aluminum Rear Main Seal Upgrade is a direct replacement part designed for EA888 1.8TSI and 2.0TSI engines. It addresses common issues such as engine stumble, misfires, check engine lights, and oil leaks stemming from a failing rear main seal and PCV valve.

The factory seal utilizes a thin rubber surface that can become brittle over time due to heat cycles and oil saturation. This upgraded solution features a billet machined plate bored to a larger diameter, allowing for a thicker, more durable Viton rubber seal that offers improved resistance to heat and fluids.
Show original supplier description
The IABED Billet Aluminum Rear Main Seal Upgrade is engineered as a permanent fix for common rear main seal failures in 1.8TSI and 2.0TSI engines, specifically those within the EA888.1, EA888.2, EA888.3, and EA888.4 generations. This enhanced design provides superior resistance to the pressures typically experienced, preventing the oil leaks that plague the stock components. The billet aluminum construction also offers increased heat and fluid resistance compared to OEM seals. This product is explicitly listed as 'Not for Sale' on the manufacturer's website, indicating it may not be available for direct purchase or is part of a specific kit. Further details regarding availability and fitment for specific vehicle models utilizing the EA888 engine platforms should be confirmed with the seller.
