Description
ISUZU 4JJ1 Cylinder Head Gasket Set 5-87815452-J 5878154520 OEM Fit
Product Overview

The Cylinder Head Gasket Set with OEM numbers 5-87815452-J, 5-87815452-0, and 5878154520 is a verified direct-fit replacement for ISUZU 4JJ1 / 4JJ1-TC / 4JJ1-TCX 2.999L diesel engines. This complete gasket kit provides all essential seals required for professional cylinder head and engine overhaul.

Working Principle

The cylinder head gasket set serves as the critical sealing system for the engine's combustion chamber and fluid passages. Each precision-engineered gasket maintains perfect seals between mating surfaces—cylinder head and engine block, intake and exhaust manifolds, oil pan, valve cover, and other critical sealing points. The head gasket withstands combustion pressures exceeding 160 bar while sealing coolant passages and oil galleries.

Failure Symptoms
  • Coolant or oil seepage at the cylinder head joint with visible fluid traces
  • Compression loss between cylinders causing misfiring, rough idle, and power loss
  • Exhaust gas bubbles in the radiator from combustion gases entering cooling system
  • Oil contamination with coolant creating milky emulsion or oil slicks in coolant
  • Persistent overheating from combustion gases in cooling system
Critical Inspection Note: ISUZU service manuals require replacing all gaskets in affected sealing paths during cylinder head removal or engine overhaul. Reusing old gaskets risks compression loss, fluid leaks, and premature engine failure. Verify correct thickness grade (notch code) against original gasket before ordering.

Fitment Verification: For 100% accurate matching, provide VIN or chassis number before ordering for verification through ISUZU global EPC system.
Important Fitment Notes: This gasket set is designed for the 4JJ1 engine family. Head gasket is available in multiple thickness grades (notch codes). Verify correct grade against original gasket or workshop manual. For resurfaced engines, check cylinder head and block deck heights before ordering.

Installation Guidelines
IMPORTANT: Engine overhaul is a professional-level operation requiring qualified diesel engine technician in clean workshop environment. All gasket surfaces must be perfectly clean, flat, and free of old gasket material.
  1. Preparation: Remove engine from vehicle or position for top-end access. Drain coolant and oil. Disconnect all hoses, wiring, and fuel lines
  2. Disassembly: Remove cylinder head bolts in reverse tightening sequence. Carefully lift cylinder head and remove all old gaskets
  3. Inspection: Check cylinder head and block decks for flatness. Inspect for cracks, corrosion, or pitting. Resurface if necessary
  4. Head Gasket Installation: Place new multi-layer steel head gasket on block dowels. Ensure correct orientation and verify notch code/thickness grade
  5. Cylinder Head Installation: Carefully lower cylinder head onto gasket. Lubricate head bolt threads and heads with clean engine oil
  6. Torque Sequence: Tighten cylinder head bolts in specified numerical order: Stage 1-2: 70 N·m each, Stage 3-4: 60°–75° turn angle each
  7. Final Assembly: Install remaining gaskets and seals. Reconnect all components. Refill with fresh coolant and engine oil
