Legendary Ford 7.3 diesel engine withstands insane tests

Smith’s Diesel Performance has decided to test the limits of robustness of Ford’s legendary 7.3-litre Power Stroke diesel engine. Using an old Ford E-Series van, the mechanics tried to destroy the engine in every possible way. Despite weeks of receiving the wrong fuels and bizarre mixtures, the bloc proved stubborn and survived all the initial tortures.

The first tests and reactions

In the first test, the team poured 37 liters of gasoline into a tank that contained half diesel fuel. The engine didn’t even oscillate. Next, the van ran with a cocktail of used engine oil, differential oil and transmission fluid. The mechanics even emptied the crankcase with the engine running at idle, filling it with an inadequate mixture of 5W-20 and 75W-90 oils.

Nitro injection, bizarre fluids and the E85 ethanol test

The following tests increased aggressiveness. The van performed a 20-second burnout by receiving nitrous oxide directly on admission. The block also faced doses of brake fluid, radiator additive and even butter. The engine failed and had strong internal knocks, but recovered normal operation after receiving a dose of cetane elevator additive.

However, the near-fatal test occurred when the workshop filled the near-dry tank with E85 ethanol. The thruster made a horrible noise and went out. However, after adding used oil and more cetane additive, the Power Stroke 7.3 was resurrected, keeping the block undefeated against destruction.
