This used OEM Audi engine long block assembly, part number 079100033N, is the complete core of the 4.0L turbocharged V8 found in the Audi A8 Quattro and S8. This long block includes the cylinder block, crankshaft, pistons, connecting rods, cylinder heads, valvetrain, and timing components already assembled. Replacing a long block addresses major issues such as bottom-end knock, low compression, or internal oil leaks that cannot be fixed with a short block or top-end rebuild alone. This genuine OEM part was removed from a late-model donor vehicle.
