Lexus LS430 persistent oil leaks despite multiple seal replacements and repairs on Lexus LS430

Some Lexus LS430 owners report experiencing persistent oil leaks even after multiple seal replacements and repairs. These ongoing issues may stem from incomplete repairs that fail to address all sources of leakage, including other components like oil pans or the rack and pinion. Additionally, improper installation of seals during previous repairs can contribute to continued leaks. Some owners find that underlying issues, such as damaged gaskets or loose cover retaining bolts, are the root cause of the problem. Furthermore, leaks can originate from multiple points within the engine or oil system, necessitating a thorough inspection to identify all potential sources. To resolve these persistent oil leaks, it is recommended that owners seek a comprehensive inspection by a qualified mechanic to ensure all repairs are performed correctly and in line with manufacturer specifications.
