VEGE Remanufactured DFA7 2.9L 177ci Compact Car Long Block Engine

Description

Thermal stress cracks between intake and exhaust valve pockets cause chronic coolant consumption across commercial utility pickups. The VEGE Remanufactured DFA7 Compact Car Long Block Engine eliminates internal coolant migration during an industrial engine rebuild. This 2.9L 177ci 6-Cylinder pushrod unit generates 140HP. Mechanics must verify upper intake manifold plenum gasket alignment before torquing fuel rails.

Cast ASTM A48 Class 30 gray iron forms the 60-degree engine case beneath reinforced European-spec iron cylinder heads. A balanced cast nodular iron crankshaft spins on bi-metal aluminum bearings inside this VEGE engine build. Cold starter operation draws 140A through standard 12V automotive electrical circuits. Total dry unrigged mass reaches 340 lbs across dimensions of 24in length, 23in width, 25in height. The stamped steel sump holds 4.5 quarts.

Key Features of VEGE Remanufactured DFA7

Fleet mechanics buy VEGE Remanufactured DFA7 Compact Car Long Block Engine units to return light service vehicles to regular routes. Every commercial long block repower integrates crack-tested thick deck cylinder heads and renewed rotating components to ensure durable performance.

• Reinforced cast iron cylinder head decks eliminate thermal cracking between center combustion chambers.
• Precision ground rocker arm shafts provide steady oil volume to upper valvetrain friction pads.
• 0.0013in connecting rod journal clearances sustain uniform hydrodynamic oil film under high engine heat.
• The DFA7 commercial core incorporates induction hardened valve seats to resist recession on unleaded fuels.
• Single piece elastomeric rear main seals lock out oil seepage at the flexplate flange.
• Plateau honed cylinder walls allow piston rings to seat fast without bore scuffing or glazing.
• Dual row timing gear sets prevent timing scatter over thousands of service route miles.

Bench Dynamometer Operational Ratings

Shop dynamometer sweeps measure this DFA7 long block engine at 140 BHP and 170 ft-lbs of torque at 3400 RPM continuous test loading. Main gallery oil pressures register 46 PSI at 190°F oil pan thermal stabilization. Exhaust runner probes reach 1210°F during sustained continuous test runs on the water brake absorber unit. Dynamic compression testing displays 170 PSI across all six cylinders within 4% balance across cylinder banks. Crankshaft total runout measures under 0.0002in TIR to protect main bearing babbit surfaces under load.

Vehicle Usability Field Standards

Throttle body linkage cables require 4 lbs of return spring resistance to guarantee positive idle closing. This 60-degree pushrod V6 powerplant is NOT engineered for marine inboard installations, transverse front-wheel drive vans, or high boost turbocharged racing setups.

• Flush out initial break-in petroleum motor oil and change the filter at 500 miles or 30 operating hours.
• Hydraulic flat tappet lifters operate with fixed pedestals requiring zero manual screw lash adjustment procedures.
• Tighten cylinder head bolts in three progressive steps using angle rotation specifications without hot retorque passes.

Crated Freight Warranty Breakdown

Built to meet the comprehensive VEGE assembly standard, this replacement long block includes a 3-Year 100,000-mile parts warranty. The timber crate carries the complete long block assembly, stamped oil pan, timing gear cover, steel valve covers, pickup tube screen, and signed dynamometer test documentation.
