After Lewis Hamilton's Mercedes-Benz unit was checked and given the all clear following the German grand prix, the FIA is moving ahead with its inspections to test manufacturers' conformity with the engine freeze.

The Hamilton check was the first in 2008, and F1's governing body announced after the Belgian grand prix that the 2.4 litre Ferrari power plant fitted to Felipe Massa's car will be the next to go under the microscope.

"These checks will be done before the Italian GP," the FIA confirmed.

The Spanish sports daily Marca, meanwhile, reports that at a bosses meeting at Spa-Francorchamps last week, the issue of apparent engine performance disparity within the engine freeze was discussed.
