@Shumi: И за кое по-точно не съм прав?
Ти сам казваш, че са ни заблуждавали. Защо?

The way the process works is that a team or engine builder must submit a report to the FIA about a part which has proved unreliable, together with photographic evidence of its failure and request a modification to that part.

This report is then sent out by the FIA to the other teams and engine makers and they have five days to voice any objections, otherwise permission to make the change is granted.

One weakness in the system is that teams are not obliged to prove that a problem occurred during a race weekend, so if a team wanted to make a performance upgrade they could deliberately cause a part to fail on the dynomometer or test bench in the factory and then request a change.

Engine builders tell me that it is very difficult for them to object to a change because they know that if a failure should happen to them later in the season, they are likely to be turned down, tit for tat, by the rival whose claim they rejected.

The problem Ferrari have been working hard to rectify relates to some of the moving parts of the engine, according to sources in Italy, such as the connecting rods and in particular the way they are fabricated, rather than their design, as I understand it.

As the engines are frozen in development terms the engine builder must have incorporated a reliability problem in the changes they made to the engine over the winter, ironically when supposedly chasing out a reliability concern from last year’s engine.

The team did have some problems on the valve system prior to the Malaysian Grand Prix and changed the system in parc ferme before the race. But Fernando Alonso recently denied suggestions that the valves were the item the team had requested the FIA to be allowed to change.
