VEGE Remanufactured DB55 3.8L 231ci High Displacement Long Block Engine

Description

Lower intake manifold gasket port degradation leaking coolant into crankcase galleys ruins commercial delivery sedans. The VEGE DB55 High Displacement Long Block Engine eliminates bearing wipe delays during commercial long block repower installations. This 3.8L 231ci 6-Cylinder unit makes 205HP. Mechanics must verify plastic coolant bypass elbow seated depth prior to tensioner bracket bolt torquing.

Poured ASTM A48 Class 30 gray iron forms the cross-bolted 90-degree V6 cylinder block. This VEGE engine core features powdered metal connecting rods, a nodular iron crankshaft, and high flow iron heads. Starter motor draw requires 160A at 12V. Dry mass equals 385 lbs, sump capacity spans 4.5 quarts, with a mounting stance spanning 24in length, 24in width, 25in height.

Key Features of VEGE DB55

Municipal supervisors choose to buy VEGE DB55 industrial engine rebuild assemblies for suburban passenger transport. The balanced pushrod valvetrain maintains high fuel economy with low maintenance downtime.

• Cylinder bore finished to 3.800in optimizes piston ring tension for clean oil control.
• Crankshaft stroke set at 3.400in produces responsive acceleration through congested urban routes.
• Aluminum frame lower intake manifold gaskets eliminate coolant migration into lifter valley oil.
• Hydraulic roller lifters prevent valvetrain friction and camshaft lobe scuffing.
• Counter-rotating balance shaft cancels engine vibration across continuous idle periods.
• The DB55 commercial core fits standard front transverse passenger vehicle subframe mounts.
• High volume oil pump feeds pressurized lubricant to connecting rod bearings under load.

Dynamometer Bench Operational Tolerances

Live dynamometer diagnostics test each DB55 long block engine before shipping crate sealing. Bench readouts verify 205 BHP and 230 ft-lbs torque output at 3600 RPM continuous load. Oil gallery pressure maintains 50 PSI at 192°F oil sump temperature. Pyrometer probes show 1120°F EGT across manifold runners. Cylinder compression reads 180 PSI across all six cylinders. Crankshaft center journal runout remains below 0.0002in TIR limit under dynamic full load testing.

Chassis Installation Limits Criteria

Throttle cable assembly demands 5 lbs pull force for smooth return spring pedal action. Do not drop this naturally aspirated pushrod engine into factory supercharged chassis or longitudinal truck engine compartments.

• Evacuate initial break-in petroleum fluid and change spin-on filter after 500 roadway miles.
• Confirm fixed torque-to-yield rocker arm bolts reach 11 ft-lbs plus 90 degrees rotation.
• Torque cylinder head fasteners in stages finishing at 37 ft-lbs plus 120 degrees rotation.
