What’s Included & Condition Notes

This is a complete long block assembly sold as removed from the donor vehicle. 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.

Critical Installation & Buyer Advisory

Dealer-Level Expertise & Precise VIN Match Required.
This is a highly complex, electronically managed engine.

• Ancillaries NOT Included (Must Transfer):

  • Turbocharger & Exhaust Manifold

  • Full Emissions Aftertreatment System (OPF/DPF, SCR Catalysts, AdBlue Injector)

  • High-Pressure Fuel Pump, Fuel Rails, and Injectors

  • Complete Engine Wiring Harness & All Sensors

  • Engine Control Unit (ECU) – This is VIN-coded.
