It includes the engine block with integrated aluminum intake manifold, cylinder head, crankshaft, pistons, valve train, oil pan, and timing case. Critical emissions components (OPF/DPF, SCR system, EGR) and turbocharger are typically NOT included unless explicitly stated and shown in photographs. Sold in “as-removed” condition; professional inspection is mandatory.
