VEGE Remanufactured DFEP 3.9L 238ci Car Truck Long Block Engine

Description

Timing cover water passage corrosion and pushrod cup galling trigger catastrophic valvetrain noise in commercial transport vans. The VEGE Remanufactured DFEP Long Block Engine eliminates premature pushrod failure through an industrial engine rebuild standard. This 3.9L 238ci 6-Cylinder assembly produces 193HP. Mechanics must verify camshaft synchronizer alignment depth before torquing the retainer clamp bolt.

ASTM A48 Class 30 gray iron forms the rigid 90-degree V6 block architecture. Metallurgy throughout this VEGE engine core incorporates an induction hardened cast iron crankshaft, forged connecting rods, and sintered iron main bearing caps. Cold cranking requires a 12V starter drawing 150A. Assembled dry weight totals 375 lbs with physical proportions of 25in length, 24in width, 25in height and a 5.0 quarts oil capacity pan.

Key Features of VEGE DFEP

Fleet technicians buy VEGE DFEP Long Block Engine units to maintain reliable cargo transport operation. Diamond honed cylinder walls establish immediate compression ring seal to streamline the commercial long block repower.

• 6-Cylinder 90-degree iron block receives automated line boring across main bearing bores.
• 12-Valve cylinder heads feature hardened exhaust valve seats to prevent thermal seat recession.
• 3.9L displacement yields 240 ft-lbs torque for moving heavy delivery freight.
• 0.0013in rod journal oil clearances maintain hydrodynamic oil separation under severe loads.
• Internal counter rotating balance shaft reduces rotational harmonic shake in passenger chassis.
• Hardened steel pushrods transmit uniform valve motion without flex distortion at high speeds.
• DFEP commercial core assemblies arrive with new pre-tested high volume oil pump units.
• Multi layer steel head gaskets eliminate coolant leaks across siamesed cylinder decks.

Test Dynamometer Performance Limits

Controlled dynamometer cell tests register 193BHP and 240 ft-lbs torque at 4400 RPM for the DFEP long block engine. Internal pressure sensors track 48 PSI oil gallery delivery at 195°F continuous sump operating temperature. Cylinder compression gauges verify 175 PSI across all six cylinders with under 3% balance variation between banks. Pyrometer readings on test manifolds confirm 1140°F exhaust gas temperatures during brake load cycles. Crankshaft journal runout remains below 0.0003in TIR across finished bearing surfaces.

Shop Clearance Usability Directives

Mechanical accelerator linkage brackets require 5 lbs manual cable pull force to achieve full throttle body rotation during operation. This engine is not built for transverse front wheel drive minivans, marine jet boats, or forced induction supercharged applications.

• Drain initial break-in motor oil at 500 miles and refill with high quality SAE 5W-30 mineral lubricant.
• Hydraulic roller lifters establish automatic zero lash operation through rigid torqued rocker arm pedestals.
• Fastener threads on cast iron cylinder heads require fresh lubrication prior to executing angle torque steps.

Commercial Warranty Crate Specifications

Operational security stems from the VEGE assembly standard 3-Year 100,000-mile commercial warranty program. Each heavy timber shipment crate houses the complete assembled long block, front timing cover, stamped steel oil pan, stamped valve covers, oil pump strainer, and certified dynamometer test report sheets.
