The ISUZU 4JJ1 is a robust and fuel-efficient 3.0L inline 4-cylinder turbo diesel engine used widely in light commercial vehicles and pickups. It features a DOHC 16-valve aluminum cylinder head и high-pressure common rail (CRDI) fuel injection, making it ideal for both urban delivery and off-road use.
Due to the engine’s high compression and operating temperature, a high-quality, pressure-tested aluminum head is crucial in both repairs and rebuilds.
