Sludge can build up in the engine because Lexus did not recommend frequent enough oil changes. Lexus will sometimes offer a discount on cleaning the engine if necessary. Owners who changed their oil every 3,000 miles did not experience these problems. This sludge build up can lead to excessive oil consumption.Google+

My Lexus problem resulted from a buildup of sludge in the engine. I had followed all the oilchange guidelines but still had a sludge buildup. Lexus agreed to install a new engine in my car even though it was older. They were very agreeable and I have always been treated with courtesy and respect as a Lexus owner. My car now runs like a new Lexus!

just bought 2003 Lexus es500 (75k miles) last week and noticed white smoke coming out of tail pipe at startup. I took car to Lexus Dealership today and found out that it has sludged engine and would cost me 12k to replace engine. I have put a call into Lexus customer relations in hope of getting this repair fixed.
