About This Used Engine Long Block Assembly — 4.0L V8 with Secondary Air Injection
This premium used engine long block assembly (131,000 miles) is a reliable, cost-effective solution to replace your Discovery II's engine, meticulously tested, cleaned, and rebuilt by expert technicians. This is the 4.0L V8 with Secondary Air Injection version — part number LBB112300N.
Every engine undergoes a comprehensive inspection process including a pre-dismantling test run, oil pan removal and bearing inspection, resealing, and valve cover service. This assembly includes the complete long block but excludes the starter, alternator, AC compressor, and power steering pump — spark plugs, fuel injectors, and water pump remain installed for shipping protection and should be replaced after installation, as they're not covered under warranty. Backed by a 6-month unlimited mileage warranty covering engine knock and excessive oil consumption under normal driving conditions.
