ISUZU 4HK1 6HK1 Nozzle Holder Sleeve 8-97606661-0 — Verified OEM Direct-Fit Injector Seal Sleeve
Product Overview

The Nozzle Holder Sleeve with OEM number 8-97606661-0 — cross-referencing to 8976066610 / 8-98018462-0 / 8980184620 — is a precision-engineered brass sealing component for the cylinder head of ISUZU 4HK1 and 6HK1 common rail diesel engines. This sleeve creates a sealed passage between the injector nozzle and the combustion chamber, preventing high-pressure combustion gas leakage while blocking coolant from entering the injector bore area.

Function Overview

The nozzle holder sleeve is installed in the injector bore of the cylinder head. Its core functions include: precisely positioning the injector nozzle, sealing the combustion chamber against gas blow-by, isolating the injector from engine coolant, and protecting the injector tip from carbon buildup and corrosion. Manufactured from precision-machined brass, the sleeve offers corrosion resistance and high strength, designed to withstand the extreme conditions of common rail injection systems.

2025 Verifiable Signal Reinforcement
  • Material & Construction: Precision-machined brass, cylindrical with flared end and threaded interface — corrosion-resistant and high-strength. Material certificate available upon request.
  • Pressure Rating: 200 bar (2,900 PSI) — withstands common rail injection pressures. Based on product specification data.
  • Temperature Range: -40 °C to 150°C (-40°F to 302°F) — based on product specification data.
  • Installation Fitment: Direct replacement for OEM sleeve in ISUZU 4HK1 / 6HK1 cylinder head injector bores — installation success rate to be supplemented from actual repair order data.
  • OEM Cross-Reference Verified: Replaces 8976066610 / 8980184621 / 8-98018462-0 / 8980184620 / 897606-6610
Failure Symptoms
  • Abnormal coolant level drop; bubbles or turbulence observed in coolant reservoir
  • Diesel odor in engine oil or abnormal oil level rise (fuel contaminating oil system)
  • White smoke from exhaust, reduced engine power, or rough idle
  • Carbon tracks or discoloration at injector bottom (typical sign of failed copper gasket)
  • Leakage at nozzle holder sleeve area during cylinder head pressure test

⚠️ Important: This is an internal engine precision sealing component. Professional repair qualification is required for installation. Please provide VIN or engine serial number before ordering for fitment verification. Simultaneous inspection of the copper gasket (OEM 8-98004187-0 or equivalent) is recommended — typically replaced together with the nozzle holder sleeve.
Features & Benefits
Feature
Benefit + Verification Signal

Quality Control & Verification
QC Item Verification Method
Dimensional inspection CMM coordinate measurement against OEM drawing (ID, OD, length)
Material composition Supplier material certificate / spectral analysis for brass composition
Surface quality Visual inspection for cracks, burrs, corrosion; sealing surface finish
Thread inspection Thread gauge inspection of threaded interface
Pressure test Per supplier hydro/pneumatic seal test report (recommended)
Packaging inspection Ensure no deformation or damage in transit

⚠️ The above QC items are industry-standard recommendations. Third-party inspection reports or bench test data should be prioritized if available.

Installation & Maintenance Recommendations
⚠️ IMPORTANT: The nozzle holder sleeve is installed inside the cylinder head and involves high-pressure fuel system components. Professional technicians with ISUZU common rail engine repair qualifications are strongly recommended. Always refer to the ISUZU workshop manual before installation.
Installation Guidelines

(Reference workshop manual):

  1. After removing the old sleeve, thoroughly clean the cylinder head bore — free of carbon, corrosion, or residual sealant
  2. Inspect copper gasket seat surface flatness — sealing surface must be perfectly clean; old copper gasket can be hand-lapped with fine compound to clean the seat surface
  3. When installing the new nozzle holder sleeve, ensure the copper gasket at the sleeve bottom is correctly seated
  4. Tighten injector clamp bolts to ISUZU-specified torque — note this is a low-torque specification; do not over-tighten
  5. Perform cylinder head pressure test after installation to confirm no leakage
  6. Recommend simultaneous replacement of copper gaskets and O-rings
Maintenance Schedule
  • Replace all nozzle holder sleeves when servicing cylinder head or performing valve work
  • Inspect sleeve sealing immediately if abnormal coolant consumption or oil contamination occurs
  • Check every 100,000-150,000 km or per engine overhaul interval
