The Red Bull Racing team has revealed that the engine removed from Mark Webber's car after Saturday morning practice in Belgium is still 'serviceable' and will remain a part of the Australian's useable allocation for forthcoming rounds.

Webber's woe followed on from a nightmare weekend for the entire Red Bull team in Valencia where, as well as not scoring points, both the Australian and fellow title contender Sebastian Vettel suffered ongoing engine problems. The German arrived at Spa-Francorchamps with just two new and two used engines remaining in his eight-unit allocation for 2009, while Webber has a similar tally of unused powerplants available.

Saturday practice saw the Australian sit out much of the hour, and then fail to set a time as he returned to the pits before completing a flying lap, with the Renault V8 being changed as a precaution before qualifying.

The team revealed, however, that despite the switch, the supposedly damaged engine was still serviceable, and confirmed that Webber still had three used engines with sufficient mileage remaining on them to be of use over the remainder of the season. Any driver exceeding the eight-engine allocation would be liable to penalty.
