VEGE Remanufactured DD57 3.9L 239ci Car Truck Long Block Engine

Description

Vacuum plenum pan gasket failure and timing chain slack trigger oil fouling in municipal cargo vans. The VEGE Remanufactured DD57 3.9L 239ci Car Truck Long Block Engine eliminates continuous exhaust smoke through a commercial long block repower. This 3.9L V6 build develops 175HP, but mechanics must verify distributor drive gear mesh against the iron camshaft gear.

Constructed around an ASTM A48 Class 30 gray iron block, this VEGE engine core utilizes remanufactured cast iron cylinder heads and a counterweighted nodular iron crankshaft. Starter draw demands 150A on 12V circuits. Bare engine weight reaches 410 lbs inside 25in length, 24in width, 26in height dimensions holding 4.5 quarts oil.

Key Features of VEGE DD57

Service managers buy VEGE Remanufactured DD57 3.9L 239ci Car Truck Long Block Engine assemblies to keep delivery vehicles on route without incurring new equipment lease costs. The upgraded aluminum belly plate maintains rigid manifold clamping to prevent crankcase oil siphoning under high-vacuum engine braking.

• Engine displacement spans 239ci across a 3.910in bore and 3.310in stroke crankshaft radius.
• Upgraded intake manifold plenum belly pan plate prevents vacuum-induced oil consumption leaks.
• Hydraulic roller camshaft and lifters eliminate flat tappet camshaft wear during protracted idle.
• Cast iron cylinder heads feature induction-hardened valve seats for unleaded fuel durability.
• DD57 commercial core precision line-boring guarantees true crankshaft journal rotation under heavy loads.
• Tri-metal copper-lead rod bearings absorb micro-particulates to prevent crankshaft journal scoring.
• Double roller timing chain sets prevent camshaft synchronization drift across severe duty cycles.

Shop Test Stand Tolerances

Hot test protocols record vital statistics on every DD57 long block engine before dispatch. The assembly generates 175HP at 4800 RPM alongside 225 ft-lbs torque at 3200 RPM. Sump oil gallery pressure stabilizes at 50 PSI at 195°F operating temperature. Cylinder compression gauges show 170 PSI across all ports with 3% variance. Crankshaft runout checks at 0.0003in TIR. Dynamic exhaust gas temp stabilizes at 1240°F under dyno loading.

Installation Demands Maintenance Guidelines

Mechanical throttle linkage operates with 5 lbs return resistance. This Magnum pushrod V6 is NOT designed for front-wheel-drive configurations, late-model CAN-bus direct-injection chassis, or early LA-engine shaft-mounted valvetrain setups.

• Flush break-in engine oil and replace the filter element after 500 highway transit miles.
• Inspect intake manifold belly pan perimeter bolts at 84 in-lbs after the first 50 operating hours.
• Check cylinder head bolt torque down to 105 ft-lbs following initial thermal normalization runs.

Factory Guarantee Crate Inclusions

Built under strict VEGE assembly standard protocols, this remanufactured powertrain includes a 3-Year 100,000-mile commercial warranty. Uncrating reveals the remanufactured long block core, oil pan, timing cover, valve covers, oil pump pickup screen, and certified test sheet.
