The Lexus LS430 remanufactured engine (part number e-r-n_10944) is a 4.3L V8 DOHC 32v unit designed for the 2006 model year. This engine is built with aluminum cylinder heads and an aluminum block, ensuring durability and performance. The remanufacturing process meticulously re-machines or replaces every component to meet or exceed original equipment manufacturer (OEM) standards. This comprehensive rebuild includes the crankshaft, connecting rods, new rod bearings, pistons, rings, camshaft, timing chain, cylinder heads with new valves, keepers, springs, seals, rocker arms, pushrods, and lifters. Additionally, a full gasket set and a new oil pump are included to ensure a complete and reliable installation. This remanufactured engine is backed by a 5-year, unlimited mileage "No Fault" warranty that is transferrable with vehicle ownership and offers nationwide coverage. The warranty includes authorized repairs reimbursed for parts and labor at a rate of $50 per hour for Mitchell labor, with labor paid only on approved claims after factory inspection. For vehicles from 2000 and older, the warranty is 3 years with unlimited mileage and the same labor rate. Included with the engine are the block casting, crankshaft, connecting rods, new rod bearings, pistons, rings, camshaft and timing chain. However, the flexplate, flywheel, harmonic balancer, intake manifold, oil pan, and timing cover are not included and will need to be sourced separately. The engine's specific options include Variable Valve Timing (VVT) and an extra bolt hole, with block cast numbers including 3UZ and factory codes like 3UZFE.
