About This Td6 Diesel Cylinder Head
A remanufactured left-side cylinder head for the Land Rover 3.0L Td6 turbocharged V6 diesel (306DT / AJD-V6), found in 2016–2021 Range Rover and Range Rover Sport and 2017–2020 Discovery diesel models. Fully assembled with valves, springs, camshafts, lifters, and rockers — ready to bolt on.
Part number LR083672 (replaces C2D50972), casting ident 9X2Q6C032BC. Aluminum DOHC construction with 16.1:1 compression. The matching right-side head (LR014249) is sold separately. Fits the 3.0L Td6 diesel only — not compatible with gasoline V6/V8 engines or the earlier 2.7L TDV6.
