Sludge can build up in the engine because Toyota 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.

    Oil was being blown out the exhaust (white smoke) making it look like it was coolant but the oil was leaking rapidly, not coolant at all. The entire engine had to be cleaned out due to sludge buildup and I am only going to run synthetic oil from now on to avoid the problem again.

    sludge stopping up the PCV system causing blown valve cover gaskets and engine had to be cleaned and flushed with valve cover gasket replacement.
