If you’re hunting for an OEM‑spec long block that drops in without drama, the Engine Assembly for K24Z1 CRV 2.4L for Honda has been getting a lot of attention in shop circles. I’ve seen it land on benches from Arizona to Auckland; mechanics like that it shows up clean, measured, and ready to button up. And yes, it comes from 289 Heping East Road, Chang’an District, Shijiazhuang, Hebei—an address many parts buyers will recognize.
The CR‑V’s K24Z1 is a DOHC i‑VTEC workhorse. Realistically, owners want a quiet cold start, solid mid‑range torque, and emissions compliance. Shops want consistent machining and paperwork. This unit checks those boxes. In fact, many customers say the NVH feels “new‑car-ish” once the mounts and ancillaries are refreshed.

- Direct replacement for 2007–2011 CR‑V K24Z1. - Fleet refresh where downtime is pricey. - Engine swap projects using CR‑V ECU and emissions gear (verify immobilizer and sensor mapping). To be honest, the cleanest results come when you keep the intake, sensors, and catalyst from the original vehicle.
Long block vs. short block, gasket set inclusion, oil pump and VTC actuator pre‑installed, dyno sheet add‑on, and export crating. Some vendors can pre‑prime with break‑in oil, which is handy.

| OEM Reman | Higher | 12–36 months | Dealership lead times | OEM program | Excellent docs; pricier |
| Salvage Yard Take‑out | Lowest | 30–90 days | Immediate | N/A | Mileage unknown; riskier |
A regional courier (mixed 2008–2010 CR‑V fleet) swapped in three Engine Assembly for K24Z1 CRV 2.4L for Honda units over six months. After 25k–40k miles each: oil consumption under 0.3 qt/5k mi, average fuel economy returned to baseline, and cold‑start clatter essentially gone. Not scientific, but it lines up with what independent shops report.
Use new TTY head bolts, OEM spec coolant, and follow torque/angle from the Honda service manual. Replace wear items (water pump, rear main seal) while the engine is out. After install, perform idle learn and CKP pattern learn—tiny steps, big difference.
