Contour SVT owners battle severe connecting rod knock and oil pressure loss caused by high-RPM oil starvation during aggressive cornering. This precision remanufactured Ford Contour SVT 2.5L Remanufactured Engine restores factory balance and oil flow. The 2.5L 6-Cylinder 24-Valve DOHC powerplant requires thorough oil system pre-priming prior to initial startup to preserve dual overhead camshaft journals.

Aluminum block casting 152 features deep-skirt architecture with cast iron cylinder sleeves align-honed to preserve bearing centerline trueness within 0.0003in. A forged steel crankshaft spins on upgraded tri-metal rod bearings clearanced to 0.0012in. Dual overhead cam aluminum cylinder heads house extrude-honed intake ports and twenty-four valves actuated by solid mechanical tappets. Crated long block weight measures 252 lbs with crated envelope dimensions of 36in length by 36in width by 36in height and holds 5.8 quarts oil.

Key Features of Ford SVT 2.5L

Automotive repair shops buy Ford SVT 2.5L remanufactured engine assemblies to restore collector-grade performance and eliminate valvetrain noise. Technicians install this remanufactured 2.5L long block replacement to resolve oil burning issues.

- Aluminum block casting 152 receives precision CNC deck milling to secure multi-layer steel head gaskets.
- Forged steel crankshaft journals undergo micro-polishing down to 0.0003in runout to eliminate bearing wear.
- SVT-grind high-lift camshafts undergo profile micrometer scanning to ensure factory valve timing duration.
- Extrude-honed cylinder head intake ports receive three-angle valve seat cutting to hold 0.001in valve runout.
- Tri-metal rod bearings maintain 0.0012in oil clearance to protect rod journals under high-RPM operation.
- Diamond plateau cylinder bore honing creates a crosshatch pattern that seats moly rings within 500 miles.
- Threaded brass oil gallery plugs replace standard press fittings to ensure sustained oil pressure at 6,800 RPM.

Dyno Load Precision Machining Tolerances

Dynamometer testing confirms 195 HP at 6,625 RPM and 165 ft-lbs shaft torque at 5,625 RPM on our computer testing cell. Machine shop inspectors verify crankshaft journal runout below 0.0003in TIR while rod bearing oil clearance measures 0.0012in. CNC cylinder bore honing holds piston-to-bore clearance at 0.0012in to prevent cold piston slap. Operating engine oil pressure sustains 60 PSI at 3,000 RPM with engine coolant stabilized at 195°F. Individual cylinder compression gauges verify balanced readings between 185 PSI and 190 PSI across all six cylinders.

Vehicle Fitment Drivetrain Guide

This remanufactured engine fits 1998 Ford Contour SVT models equipped with the 2.5L 2544cc Duratec 25 SVT V6 Engine VIN Code G and body style code 152. It bolts directly to the MTX-75 5-Speed Manual front-wheel-drive transaxle. This long block does not fit standard 170 HP base Contour 2.5L models, Mercury Mystique base trims, automatic transaxle configurations, or late 1999 to 2000 returnless fuel system SVT platforms.

Installation Protocol Service Requirements

Check dual-stage intake manifold butterfly actuation and examine oil pan baffle clearances before lowering the long block into the engine subframe. Never operate this naturally aspirated high-output V6 in forced-induction race chassis or stripped off-road buggies lacking secondary oil filtration. Mechanics must verify correct fuel rail return line routing before first ignition.

- Pressure-prime internal oil channels with 5W-30 synthetic motor oil before starter engagement to protect camshaft lobes.
- Drain the factory break-in motor oil and install a high-micron oil filter at 500 miles.
- Inspect primary timing chain tensioners and check water pump belt tension at 3,000 miles.
