Jun.23 (GMM) Christian Horner is not ruling out a five-place grid penalty for Sebastian Vettel in Valencia.
Vettel's Red Bull teammate Mark Webber lost his front-row starting place in Canada due to needing a precautionary gearbox change prior to the race.And Vettel finished the Montreal race with a different gearbox problem, meaning that if it needs to be changed at Valencia during its four-race life, the German will also be penalised.According to a report in the Cologne publication Express, there is a possibility the Montreal gearbox is damaged.Horner is quoted as saying Vettel's problem in Canada was "an oil leakage".But as for whether the gearbox will be changed, the team's British boss added: "We must look into that."
