Audi 079103052AL Crankshaft Housing / Lower Engine Block – a used OEM part from a donor vehicle, also known as the lower engine block. This casting replaces 079103011P, 079103011AE, and 079103011AA. It houses the crankshaft in the 4.2L V8 (4163CC and 4172CC) gas DOHC engines from the Audi A6, Allroad, and S4. A cracked or warped housing can cause oil leaks or main bearing failure, requiring full engine disassembly to replace.
