Why do TDI engines last longer?

In addition to more oil and coolant capacity diesel engines are simply built with heavy duty components that wear out less frequently. Diesel engines are built with a simple yet durable valve train. The rollers are harder and more solid than in gas engines and there are no hydraulic lifter failures to worry about.

What is VW strongest TDI engine?

Without a doubt, the most powerful and torquiest diesel engine the Volkswagen Group ever made was its 6.0-liter twin-turbo V12. It's the only twelve-cylinder diesel engine we've ever seen in a production automobile, producing an impressive 493 horsepower and a gravity-altering 738 lb-ft of torque.

What happens if TDI timing belt breaks?

First, the camshaft stops moving, and all timing is lost. Then, the pistons crash into the valves, damaging both parts. Depending on how hard the pistons and valves collide, you might also end up with decimated cylinder walls. The broken timing belt basically takes out this entire portion of the engine.

How much HP can a 1.9 TDI handle?

With more extensive work (rods, better crank, cam, valve relieved pistons, larger injection pump), 300 hp is achievable, but for one of the most extreme examples of what a 1.9L TDI can do, look no further than the 350 to 400hp version pictured above.
