Stuck piston oil control rings and clogged intake manifold exhaust recirculation ports generate severe oil consumption on fleet transport cars. The Acura Honda F23A1/A4 2.3L L4 Remanufactured Engine 1998-2002 eliminates ring sticking throughout this commercial long block repower. This 4-Cylinder 150HP SOHC powerplant requires balance shaft drive belt tension verification before securing the outer timing cover.

Cast A356-T6 aluminum forms the open-deck crankcase displaying driver and passenger side PAA casting marks. Centrifugal spun iron cylinder liners house anti-friction coated pistons connected to a forged steel crankshaft with tri-metal bearings. This Acura Honda engine core pulls a 12V 145A starter draw during cold startup tests. The unit weighs 180 lbs dry, occupying a 24in length, 23in width, 25in height stance holding 4.5 quarts of oil.

Key Features of Acura Honda F23A1/A4

Regional dispatch directors buy Acura Honda F23A1/A4 2.3L L4 Remanufactured Engine 1998-2002 packages to keep highway transport vehicles operational. Our industrial engine rebuild standard incorporates upgraded low-tension oil control rings and clear manifold recirculation channels.

- Cylinder bores machine to 3.386in with diamond plateau hone cross-hatch finishes.
- Main bearing journal clearance holds at 0.0014in across the five-bearing crankcase.
- VTEC rocker arm pins receive ultrasonic cleaning and hydraulic pressure testing.
- Dual counter-rotating balance shafts eliminate second-order engine vibration buzz.
- Multi layer steel head gaskets stop combustion blowby into the coolant passages.
- This F23A1 commercial core features micro-polished crankshaft journals flat within 0.0002in.
- Induction-hardened valve seat inserts resist unleaded gasoline recession wear.

Brake Cell Load Verification

Automated brake cell test logs verify that this F23A1 long block engine produces 150 continuous BHP and 152 ft-lbs of torque at 4800 continuous load RPM. Internal oil gallery pressure measures 55 PSI while oil sump temp levels at 193°F under full brake load. Exhaust gas temp tops at 1270°F along the manifold collector. Cylinder compression checks between 178 PSI and 185 PSI across all four cylinders. Crankshaft center journal runout holds within 0.0002in TIR.

Field Assembly Setup Boundaries

Automatic transmission throttle kickdown cables demand 5 lbs of pull force to maintain proper downshift control under vehicle acceleration. This 2.3L motor is not intended for forced induction track racing, marine outboard setups, or stationary generator pump skids.

- Evacuate initial break-in petroleum motor oil after 500 miles or 30 run hours.
- Verify cold intake valve clearance at 0.010in and exhaust clearance at 0.012in.
- Torque cylinder head fasteners in three stages to 76 ft-lbs final specification.

Factory Warranty Crate Manifest
