Honda CR-V K24Z6 VTEC 2.4L L4 Engine 12488E 2010-2014

Description

Cold start variable valve timing phaser chatter and oil control ring carbon binding cause excessive tailpipe smoke and timing codes. The Honda CR-V K24Z6 Engine eliminates these chronic sport utility valvetrain failures during commercial long block repower procedures. Delivering 185HP, this 2.4L 4-Cylinder unit requires verified intermediate half-shaft carrier alignment to avoid transaxle fluid leakage.

Open-deck ASTM A356-T6 cast aluminum forms the cylinder block and head castings, reinforced with centrifugal cast iron liners. This Honda engine core incorporates an induction-hardened AISI 4340 forged steel crankshaft stamped R40, supported by tri-metal bearings. Starter draw pulls 145A at 12V across bench test sequences. Total unrigged weight equals 210 lbs with external dimensions of 38in length, 38in width, 38in height, with a 4.4 quarts oil capacity.

Key Features of Honda K24Z6

Fleet facilities buy Honda K24Z6 commercial long block engines to resolve persistent oil consumption during industrial engine rebuild cycles. Multi-axis CNC honing equipment produces precise crosshatch patterns to guarantee rapid piston ring seal and long term bore geometry.

• Crankcase casting stamped K24Z6 and cast R40 confirms factory sport utility specification.
• Upgraded intake VTC gear eliminates cold startup rattle and cam phase diagnostic codes.
• Internal balance shafts cancel secondary engine vibrations for smooth passenger cabin operation.
• Forged steel crankshaft marked R40 provides superior fatigue strength under continuous load.
• The K24Z6 commercial core features low friction piston coatings to resist bore scuffing.
• Chain driven high volume oil pump maintains reliable lubrication across all variable valve events.
• Multi layer steel head gaskets eliminate combustion blowby between high pressure fire rings.
• Viton crankshaft seals prevent oil seepage into external accessory drive compartments.

Dynamometer Inspection Load Parameters

Dynamometer testing certifies 185HP at 7000 RPM and 163 ft-lbs torque at 4400 RPM under continuous dyno evaluation schedules. Oil gallery operating pressure measures 55 PSI at an oil sump temp of 195°F. Cylinder compression holds 185 PSI across all four cylinders with total variance restricted below 4%. Crankshaft main journal runout checks show less than 0.0003in TIR across all bearing surfaces. This K24Z6 long block engine maintains continuous exhaust gas temp readouts below 1310°F during simulated grade ascent tests.

Chassis Fitment Platform Scope

Direct replacement fitment covers 2010 to 2014 Honda CR-V sport utility vehicles across front wheel drive and Real Time all wheel drive trims. This long block bolts direct to factory 5-speed automatic transmissions, utilizing original aluminum side engine brackets, front snubbers, and single port exhaust manifold connections without chassis modifications.

Field Usability Maintenance Guidelines

Electronic throttle bodies require proper idle relearn routines following battery reconnections. Field mechanics must note this long block is NOT engineered for manual transmission Civic Si K24Z7 platforms, earlier K24A1 CR-V chassis, or Accord K24Z3 applications due to different intake manifold port angles, single exhaust port geometry, and accessory mount bosses.

• Replace initial break-in engine oil and filter after 500 road miles or 20 hours.
• Check cold valve lash to 0.009in intake and 0.011in exhaust during initial 30,000-mile maintenance.
• Clean the VTC oil control strainer screen during every second scheduled oil change service.

Packaging Manifest Warranty Protection

Protected by a 3-Year 100,000-mile parts warranty, each remanufactured assembly complies with strict Honda assembly standard specifications. The heavy duty wooden shipping crate contains the long block core, cast aluminum oil pan, front timing cover, valve cover, oil pump pickup tube, and signed dynamometer test documentation.
