VEGE DA31 4.0L 242ci Premium Grade Long Block Remanufactured Crate Engine

Description

Regain dependable all-terrain crawling power with the VEGE DA31 Remanufactured Crate Engine premium long block package. Displacing 4.0L across 242ci in an inline six-cylinder format, this motor generates 190 BHP at 4600 RPM and 225 lb-ft torque at 3000 RPM. Engineered for multi-port fuel injection, it repowers utility trucks while eliminating oil consumption, smoke, and valvetrain noise.

A deep-skirt cast iron engine block features precision decked surfaces with a 3.875-inch cylinder bore and 3.414-inch stroke. The rotating group incorporates a balanced nodular iron crankshaft, forged connecting rods, and premium hypereutectic aluminum pistons. Cylinder pressure achieves an 8.8:1 compression ratio for standard fuel operation. A 6.0-quart steel rear-sump oil pan ensures steady oil pickup under steep angles. Total dressed dry weight checks in at 485 lbs for solid chassis traction.

Key Features of VEGE DA31

Discerning four-wheel-drive owners buy VEGE DA31 crate engine units to cure rear main seal weeping and cylinder head cracks in high-mileage utility trucks. Each premium remanufactured long block features upgraded multi-layer steel head gaskets, micro-finished bearing journals, and upgraded valve stem seals for extended service life.

• 3.875-inch cylinder bores receive plateau honing to seat piston rings fast.
• Overhead valve pushrod valvetrain provides twelve valves of high-grunt low-end torque.
• 48.5mm intake valves and 38mm exhaust valves promote efficient cylinder scavenging.
• 56cc combustion chambers eliminate detonation knock when burning standard 87-octane pump gasoline.
• Multi-layer steel head gaskets seal combustion fire rings under all temperature extremes.
• Upgraded viton valve stem seals inside the VEGE DA31 head halt oil consumption.
• Seven-bearing crankshaft runs on micro-polished tri-metal main and rod bearings.
• Stamped steel rear-sump oil pan clears front drive axle housings and steering linkage.

Combustion Dynamics Dyno Output Specs

The power curve delivers consistent torque output between 800 and 5,000 RPM. Peak dynamometer output reaches 190 brake horsepower at 4,600 RPM alongside 225 lb-ft torque at 3,000 RPM. Camshaft duration measures 198 degrees on intake and 206 degrees on exhaust at 0.050-inch lift, alongside 0.424-inch valve lift. The motor runs on standard 87-octane regular pump unleaded gasoline. Intake manifold vacuum pulls 19.5 in-Hg at a smooth 650 RPM idle. Operating oil pressure regulates between 40 and 65 PSI at 2,500 working RPM.

Drivetrain Interface Engine Bay Clearance

The rear bellhousing pattern aligns flush to longitudinal manual and automatic truck transmissions. An internal neutral balance crank flange connects straight to production flywheels or torque converter flexplates. Standard block mounting pads align with chassis rubber isolators, preserving four inches of clearance above the front axle housing and steering box.

Break-In Protocol Maintenance Parameters

Pre-lube all engine oil passages with a pressurized tank before initial startup to protect journal bearings. Fill the crankcase with SAE 10W-30 high-zinc mineral break-in oil and bleed trapped air bubbles from heating circuit hoses. This premium inline-six motor is not engineered for turbocharging exceeding 7 PSI boost, competitive mud racing, or unmetered nitrous oxide injection.

• Run motor at 2,000 RPM for 20 minutes to bed in flat tappet camshaft lobes.
• Drain initial break-in oil and install a fresh oil filter after the first 500 miles.
• Replace crankcase motor oil and inspect drive belts every 3,000 miles during regular service.

Verified Warranty Physical Crate Manifest

A 36-Month / 100,000-Mile nationwide limited warranty provides long-term mechanical protection against defects. The heavy transport crate contains the remanufactured long block, stamped steel oil pan, aluminum timing cover, harmonic damper, stamped valve cover, oil pressure verification report, and an installation instruction handbook.
