Lexus LS 460/500h Engine Oil Leak Repair Malaysia
LS 460 V8 oil leak hotspots at high mileage: valve cover gaskets (both banks combined), front crankshaft seal, timing cover. LS 500h is less leak-prone. Any leak dripping onto the hot exhaust must be addressed immediately — the LS's tight engine bay makes oil leaks dangerous.
LS Oil Leak Sources
- 1UR-FSE V8: valve cover gaskets on both banks — seepage at 100,000 km+
- Rear main seal: high-mileage LS, especially with extended oil intervals in history
- Inspect for oil near VVT actuators — sludge from poor oil maintenance can block passages causing external weeping
