Turbo engines are not as reliable as N/As because they generally run hotter under more stress & use up oil faster. The issue w/cylinder #3 is that the turbo is right next to it, so the heat from the turbo is always sinks into that side of the engine, which is already hot, causing more heat to build up. The H6s do not have these kinds of problems.
