VEGE Remanufactured DCB4 3.1L 189ci Car Truck Long Block Engine

Description

Lower intake manifold gasket splits and coolant washed rod bearings sideline high mileage fleet courier sedans. The VEGE Remanufactured DCB4 Long Block Engine eliminates crankcase contamination through an industrial engine rebuild protocol. This 3.1L 189ci 6-Cylinder assembly produces 160HP. Installers must note differing intake and exhaust pushrod lengths during valvetrain installation to prevent valve binding.

ASTM A48 Class 30 gray iron forms the deep skirt 60-degree V6 crankcase to resist cylinder bore ovality under load. This VEGE engine core incorporates a balanced cast iron crankshaft, forged connecting rods, and graphite coated hypereutectic pistons. Initial starter draw consumes 145A on standard 12V circuits. Dry mass measures 350 lbs with exterior boundaries of 24in length, 24in width, 24in height and a 4.5 quarts oil pan.

Key Features of VEGE DCB4

Fleet operators buy VEGE DCB4 Long Block Engine inventory to restore dependable service in light delivery vehicles. High tolerance line boring restores main bearing bore roundness to optimize oil pressure during each commercial long block repower.

• 6-Cylinder 60-degree block receives automated CNC plate honing for immediate ring seating.
• 12-Valve cylinder heads incorporate hardened exhaust valve seats to resist thermal recession under load.
• 3.1L displacement yields 185 ft-lbs torque across municipal delivery speed bands.
• 0.0013in rod journal clearance provides uniform hydrodynamic oil separation under severe operation.
• Roller hydraulic lifters minimize internal friction and protect camshaft lobes from cold start wear.
• Color coded pushrods distinguish intake from exhaust valvetrain positions to prevent assembly errors.
• DCB4 commercial core assemblies arrive with brand new high pressure oil pump units.
• Multi layer steel head gaskets eliminate coolant leaks across siamesed cylinder decks.

Dynamometer Operating Benchmarks Limits

Dyno testing protocols measure 160BHP and 185 ft-lbs torque at 5200 RPM for each DCB4 long block engine. Standard pressure sensors indicate 45 PSI oil gallery delivery with oil pan lubricants held at 195°F during full power runs. Cylinder compression checks register 175 PSI in each bore with variance restricted within 3% between cylinder banks. Pyrometer sensors record 1140°F peak exhaust temperature under dyno load sweeps. Calibrated bench indicators confirm crankshaft journal runout remains below 0.0002in TIR across finished bearing surfaces.

Field Installation Directives Exclusions

Mechanical throttle linkage return springs demand 4 lbs manual pull effort to stroke the throttle body mechanism during pedal travel. This engine is not built for rear wheel drive trucks, supercharged drag racers, or marine inboard hulls.

• Drain initial break-in petroleum motor oil at 500 miles and replenish the crankcase with SAE 5W-30 mineral oil.
• Hydraulic roller lifters seat within zero lash envelopes without manual valve adjustment shims.
• Cast iron cylinder heads require clean oiled bolt threads and strict angle torque execution on assembly.

Warranty Terms Shipment Manifest

Commercial vehicle investments receive coverage under the VEGE assembly standard 3-Year 100,000-mile warranty policy. The heavy timber transport crate houses the complete assembled remanufactured long block, front timing cover, stamped steel oil pan, stamped valve covers, oil pump pickup screen, and verified dyno performance test sheets.
