What causes sludge build up in engine?
Causes. Sludge is usually caused by a poorly designed or defective crankcase ventilation system, low engine operating temperatures, the presence of water in the oil or crankshaft-induced cavitation, and can accumulate with use.
What causes Toyota engine sludge?
After prolonged exposure to high heat, engine oil can oxidize and break down, forming deposits known as sludge. In a related case, Toyota settled a class-action engine-sludge suit in 2007 that covered an estimated 2.5-million Toyota and Lexus vehicles made between 1997 and 2002.
Is engine sludge a problem?

Why is the oil sludging up in my car?
In some situations, oil additives are burned off or destroyed; then oxidation occurs and pollutants congregate in the oil, producing sludge and varnish. Originally, it was thought that the oil was being “burned” by excessive heat, but the sludge may be caused by problems with crankcase ventilation, at least in some cases.
