The torque setting for the cylinder head bolts on the Isuzu 4JB1 engine is typically around 70-80 Nm (51-59 lb-ft) for the initial torque. It's essential to follow a specific tightening sequence and perform a final angle torque of around 90 degrees to ensure proper clamping. Always refer to the manufacturer's service manual for the most accurate and detailed specifications, as variations may exist based on engine condition or updates.
The torque settings for a 4JB1 engine will vary depending on the specific component being tightened. For example, the cylinder head bolts may require a torque setting of around 90-100 Nm, while the main bearing cap bolts may need to be tightened to 130-140 Nm. It is crucial to consult the manufacturer's specifications or a reliable repair manual to ensure the correct torque settings are applied to each component to prevent damage or failure.
there is a plate on the firewall which has its identification engine should be 4jb1 (2.8 diesel) or 4ze1 (2.6 petrol)
The valve clearance for the Isuzu 4JB1 engine is typically set at 0.20 mm (0.008 inches) for the intake valves and 0.25 mm (0.010 inches) for the exhaust valves when the engine is cold. It's important to check and adjust the valve clearance regularly to ensure optimal engine performance and longevity. Always refer to the specific service manual for detailed specifications and procedures.

The Isuzu 3.1 engine, commonly referred to as the 4JB1, is a 2.8-liter diesel engine often found in Isuzu vehicles. It shares some compatibility with the Isuzu 4JG2 engine, which is a 3.1-liter diesel engine. Both engines are part of Isuzu's family of diesel engines, but direct interchangeability can depend on specific vehicle models and configurations. Always consult technical resources or a professional mechanic for precise compatibility information.
For new engine (2011-2012) 13-16kms/L For used engine (2000-2010) 10-13kms/L For old engine (1997-2000) 9-11 kms/L
The Isuzu Sportivo and Isuzu Crosswind are both equipped with similar engine types, specifically the 4JA1 and 4JB1 diesel engines. However, variations in tuning and specifications may exist between the two models, affecting performance and efficiency. Overall, while they share a common engine lineage, the specific configurations can differ based on the model year and market.
