VEGE Remanufactured DFKE 4.6L 281ci Custom Series Long Block Engine

Description

Plastic timing chain guide fragmentation and oil filter adapter gasket erosion disable commercial delivery vans. The VEGE Remanufactured DFKE 4.6L 281ci Custom Series Long Block Engine eliminates timing guide failure through an industrial engine rebuild. This 4.6L 8-Cylinder SOHC build makes 225HP, requiring technicians to inspect heater core coolant pipe O-rings in the engine valley.

Constructed around an ASTM A48 Class 30 gray iron block, this VEGE engine core houses aluminum 2-valve heads and an induction-hardened cast iron crankshaft. Cold starter draw pulls 155A at 12V. Dry weight registers 480 lbs inside 28in length, 28in width, 27in height dimensions with 6.0 quarts oil capacity.

Key Features of VEGE DFKE

Commercial transport fleets buy VEGE Remanufactured DFKE 4.6L 281ci Custom Series Long Block Engine assemblies to keep delivery shuttles on schedule without costly vehicle replacements. Cast iron timing chain tensioners replace failure-prone plastic tensioners to maintain stable chain tension and oil pressure during protracted idling.

• Bore diameter measures 3.552in paired with a 3.543in stroke to deliver dependable commercial torque.
• Cast iron timing tensioners eliminate oil pressure bleed-down and timing chain guide slap.
• Full-depth steel spark plug thread inserts prevent high-pressure blowout failures permanently.
• Micro-finished overhead camshaft journals minimize friction inside the aluminum cylinder head towers.
• DFKE commercial core alignment boring ensures true crankshaft rotation under heavy pulling conditions.
• Hydraulic lash adjusters provide zero-maintenance valvetrain operation throughout engine life.
• Multi-layer steel head gaskets lock high combustion pressures inside cylinder bores under load.

Dyno Test Cell Metrics

Testing on every single DFKE long block engine guarantees factory-spec power delivery. The assembly achieves 225HP at 4800 RPM and 286 ft-lbs torque at 3500 RPM. Sump oil gallery pressure holds 52 PSI hot at 195°F operating temperature. Cylinder compression verifies 170 PSI across all cylinders with 3% variance. Crank journal runout limits to 0.0003in TIR. Steady exhaust gas temp settles at 1220°F under dyno loading.

Operational Exclusions Setup Protocols

Mechanical throttle lever operation needs 5 lbs pull resistance. This SOHC 2-valve modular unit is NOT suited for 3-valve or 4-valve modular harness applications, direct-injection computer platforms, or transverse front-wheel-drive sedans.

• Perform break-in oil and filter changes following the initial 500 miles of highway driving.
• Inspect front accessory drive belt tensioner alignment after the first 100 hours of run time.
• Check cam cover perimeter fastener torque to 8 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, cam covers, oil pump pickup screen, and certified test sheet.
