1NR-FE
"The 1.33 petrol in the Yaris XP90/XP130, Auris and Corolla E150/E180, iQ, Urban Cruiser and Verso-S. Chain-driven, port injection, no turbo. German and French used-car data rate it durable, but it is known for oil consumption that grows with mileage, and engines run low on oil can fail. Check the dipstick and the service history."
2GR-FE/FSE/FKS/FXE/FXS
"Toyota and Lexus 3.5 V6 (RX 350/450h, IS 350, RC 350, Camry, Highlander, RAV4 V6). Long-lived and smooth, with known but manageable leaks: early engines (to 2010) need the all-metal VVT-i oil line that replaced a rubber hose under a Toyota campaign, the front timing cover can seep (engine-out on the RX), water pumps wear, and 2016-2018 FKS engines had a cam-housing leak bulletin."
