Lower intake manifold gasket breakdown allows coolant intrusion into the oil crankcase on high-mileage fleet sedans. The VEGE Remanufactured DCHC 3.1L 189ci Premium Grade Long Block Engine eliminates internal bearing washdown during this commercial long block repower. This 6-Cylinder 140HP pushrod powerplant demands strict coolant passage sealing checks before reinstalling upper induction hardware.

Dense ASTM A48 Class 35 cast iron forms the rigid 60-degree V6 block paired with precision aluminum cylinder heads. A balanced cast nodular iron crankshaft spins in tri-metal copper-lead bearings with two-bolt cast main caps. This VEGE engine core draws a 12V 155A starter load during sub-zero test cranks. Total dry weight is 295 lbs, measuring 24in length, 23in width, 25in height, with a 4.5 quarts oil capacity.

Key Features of VEGE Remanufactured DCHC

Corporate fleet supervisors buy VEGE Remanufactured DCHC Premium Grade Long Block Engine builds to cure persistent engine overheating. Every industrial engine rebuild receives diamond-machined cylinder head decks and upgraded intake sealing land geometries.

- Cylinder bores measure 3.504in with diamond plateau honed cross-hatch finishes.
- Main bearing journal clearance holds at 0.0014in across the four main journals.
- Upgraded multi layer steel head gaskets eliminate cylinder fire ring distortion.
- Hydraulic roller lifters receive magnetic particle inspections to stop valvetrain wear.
- Hardened valve guide inserts prevent oil migration past intake valve stems.
- This DCHC commercial core includes micro-polished crankshaft journals flat within 0.0002in.
- Connecting rod assemblies balance within two grams across the whole set.

Brake Dyno Load Output

Automated test cells certify that this DCHC long block engine produces 140 continuous BHP and 185 ft-lbs of torque at 3600 continuous load RPM. Internal oil gallery pressure measures 54 PSI with oil sump temp stabilizing at 192°F under full thermal loading. Exhaust gas temp tops out at 1250°F down the test header runners. Cylinder compression registers between 172 PSI and 180 PSI across all six cylinders. Crankshaft snout runout checks out at 0.0003in TIR.

Chassis Placement Excluded Usages

Transmission kickdown linkages need 5 lbs of linear pull force to guarantee proper shift timing under road acceleration. This pushrod motor is not designed for twin-turbo racing cars, marine hovercraft, or high-vibration sawmill skids.

- Drain initial break-in petroleum motor oil after 500 miles or 25 operating hours.
- Check non-adjustable hydraulic roller lifter preload at 0.020in to 0.040in cold.
- Torque cylinder head bolts to 33 ft-lbs then add 90 degrees rotation.

Commercial Protection Crate Manifest

Our trusted VEGE assembly standard backs each long block with a 3-Year 100,000-mile commercial warranty. Every crated shipment includes the remanufactured long block core, steel oil pan, front timing cover, aluminum valve covers, oil pickup tube, and signed dyno load sheet.
