Eliminate chronic cylinder head cracking and coolant consumption across commuter vehicles with this Chevy Cavalier 2.2L Remanufactured Engine. Each 2.2L 4-Cylinder 8-Valve OHV long block features casting 554 iron block metallurgy and refreshed aluminum cylinder heads. Technicians must perform pressurized oil priming before initial cranking and execute an exact 500-mile break-in oil change to protect pushrod lifters.

Built with cast iron block casting 10068554 or 10103566, this pushrod assembly features trigger fire ignition sensor provisions and round intake port geometry. The rotating foundation features a micro-polished nodular iron crankshaft casting 1237, balanced connecting rods, and oversized hypereutectic pistons. The 8-Valve aluminum cylinder head casting 738 or 049 receives diamond deck milling for head gasket retention. Dry weight measures 240 lbs within crated dimensions of 36in length by 36in width by 36in height. Sump capacity equals 4.0 quarts.

Key Features of Chevrolet 2.2L

Automotive fleet mechanics buy Chevrolet 2.2L remanufactured engine long blocks to restore fuel efficiency and pass state tailpipe emissions. This long block replacement provides factory-matched machine shop tolerances for front-wheel-drive economy passenger cars.

- Aluminum cylinder head casting 738 receives pressure decay testing to rule out internal thermal cracks.
- Round intake ports maintain optimized air charge velocity for efficient low-RPM fuel atomization.
- Block casting 554 features precision align-honed main saddles to preserve crankshaft centerline roundness.
- Crankshaft casting 1237 journals receive micro-polishing to hold total indicator runout under 0.0003in TIR.
- Diamond plateau honed cylinder walls establish an Ra 16 micro-inch finish for rapid ring seating.
- Multi-layer composite cylinder head gaskets prevent combustion gas leakage across aluminum head decks.
- Trigger fire ignition crankshaft sensor provisions ensure accurate ignition pulse timing to the engine computer.

Dyno Bench Clearance Machining Specifications

Dyno cell spin testing verifies mechanical oil gallery pressurization and power output prior to crate shipment. The 2.2L 134ci OHV engine produces 95 HP at 5,200 RPM and 120 ft-lbs of shaft torque at 3,600 RPM. Crankshaft main journal oil clearance holds between 0.0011in and 0.0015in, while connecting rod clearance measures 0.0012in. Individual cylinder compression gauges verify 175 PSI across all 4 cylinders. Hot engine oil pressure maintains 50 PSI at 3,000 RPM with regulated coolant operating temperatures steady at 190°F.

Vehicle Fitment Drivetrain Guide

This engine fits 1990 to 1991 Chevrolet Cavalier, Chevrolet Beretta, Chevrolet Corsica, and Pontiac Sunbird models carrying VIN Code G with block casting 554 or 566 and round intake ports. Drivetrain compatibility includes transverse front-wheel drive paired with 5-Speed manual transaxles or 3-Speed automatic transmissions. This unit does not fit earlier TBI engines without trigger fire ignition, rear-wheel-drive S10 pickup trucks, or later 1994 D-port cylinder head variants due to intake runner and bellhousing divergence.

Installation Protocol Service Requirements

Technicians must inspect the crankcase trigger fire sensor o-ring, check throttle body gasket sealing, and purge cooling air from the radiator bleeder screw during installation. Operational warnings restrict use in custom forced induction turbo conversions exceeding 5 PSI boost or demolition derby vehicles lacking auxiliary oil cooling.

- Pre-fill the spin-on oil filter and prime engine lubrication passages with 10W-30 conventional motor oil.
- Drain initial break-in oil and install a replacement oil filter at the 500-mile service marker.
- Inspect pushrod rocker arm nut torque and check ignition sensor wiring at 1,500 miles.
