Billet Aluminum Rear Main Seal

The 034 Motorsport Billet Aluminum Rear Main Seal offers a robust solution to the common issue of leaking rear main seals on 2.0T TSI and other compatible Volkswagen and Audi engines. The factory stamped steel rear main seal is prone to failure over time, leading to oil leaks between the engine and transmission, which can also contribute to crankcase pressure problems and even engine misfires. This upgrade addresses those issues by replacing the OEM component with a precision-engineered part. Constructed from CNC-machined 6061-T6 billet aluminum, this rear main seal holder is anodized in gloss black for durability and aesthetics. It incorporates an OEM Elring FPM fluroelastomer Viton seal, complete with an integral tension spring to ensure a consistently tight seal against the crankshaft. This design is a significant improvement over the factory's PTFE sealing lip, offering superior longevity and reliability under demanding conditions. The kit includes the billet rear main seal holder, the Elring rear main seal, and new Grade 8.8 mounting hardware. Installation requires careful adherence to the workshop manual (WSM) procedures. It is crucial to use an oil-resistant RTV sealant (typically black) or another VAG-approved sealant as specified. Bolts in the kit should be torqued to 9Nm. During installation, a guide sleeve from the repair kit should be pushed onto the crankshaft, and it's important not to apply oil to the sealing lip of the seal. Ensure the sealing lip of the sealing ring is not folded back or damaged during the installation process. The product is listed as a direct replacement for OEM Part Number 06K-103-171G. This rear main seal is designed for a wide range of Audi and Volkswagen models equipped with 2.0T engines, as well as some 1.8T Gen3 engines. Specific fitment notes indicate that for Audi A3 8P and Volkswagen EOS/Golf V models, it is for vehicles with TSI engines only. Always use the vehicle selector to confirm precise fitment for your specific vehicle.
