Lexus NX 200t/300/300h Oil Leak Diagnosis & Repair Malaysia
NX 200t/300 turbo oil leak points: turbo oil feed line banjo bolt seals (inspect every 40,000 km), valve cover gasket, and crankshaft front oil seal at high mileage. Turbo oil leaks cause smoke from the exhaust and oil burning smell — address promptly. NX valve cover gasket. Turbo oil line seals. NX 300h is much less prone to leaks.
NX Oil Leak Sources
- NX 200t turbo: oil return line seals — inspect at 80,000 km, especially if you see blue smoke on hard acceleration
