Lexus LS429 Replacement Engines
The Lexus LS429 evolved through multiple generations from 1991 to present: UCF20/UCF30 (1991-2006) with 1UZ-FE/2UZ-FE engines, UCF50/UCF60 (2006-2017) introducing 2GR-FE/3UR-FE families, and later generations with advanced VVT-i systems. All 1UZ-FE engines (UCF20/UCF30) suffered timing chain tensioner failures addressed in Toyota Service Bulletin TSB-001-98, while UCF50/UCF60 3UR-FE V8 engines share HPFP weaknesses regardless of trim (LS460-LS600h). The later generations adopted direct injection systems with revised cooling but inherited VANOS vulnerabilities from predecessors.
