This is a summary of a video about the worst internal combustion engines of the 21st century. The video covers 10 engines from different manufacturers and explains their main problems and defects. The engines are:
- BMW N20, a 2-liter turbocharged petrol engine with a plastic timing chain guide that breaks easily and causes the timing to skip.
- PSA 1.6 THP, a turbocharged petrol engine with direct injection that suffers from carbon deposits, faulty injectors and timing issues.
- Volkswagen TSI and TFSI, a group of turbocharged petrol engines with direct injection that have problems with piston rings, bearings, carbon deposits and timing chain.
- Subaru 2.0D, the world's first diesel boxer engine that has issues with clutch, flywheel, crankshaft, EGR valve and DPF.
- Toyota 2.2 D-4D, a diesel engine with direct injection and D-CAT system that has high fuel consumption, cylinder liner wear, injector failure and cooling system leaks.
- GM LFX, a 3.6-liter petrol V6 engine that has problems with spark plugs, ignition coils, oil pressure and oil leaks.
- BMW N47, a 2-liter diesel engine with a chain timing drive that is located at the rear of the engine and is prone to stretching and breaking.
- BMW N63, a twin-turbocharged 4.4-liter petrol V8 engine that has reversed gas flow and generates excessive heat that damages injectors, pistons, valves and timing chain.
- PSA/Ford 2.7 HDI, a diesel V6 engine that has problems with rotating bearings, crankshaft, injectors, EGR valve and cooling system.
- Ford Triton, a 5.4-liter petrol V8 engine with 3 valves per cylinder that has problems with spark plugs, ignition wires, fuel pump and timing chain.
The video concludes by noting that most of the engines have timing chain issues and advises checking the car's history before buying a second-hand car. The video also thanks its sponsors and invites viewers to comment and subscribe.
