Just taken the engine cover off and noticed , some residue of oil on the right side up near cylinder head (looking from front of car) have wiped off as much as possible, doesn't look like gasket is weeping as such but will keep an eye on it, just wondering if it's where they've fiiled up with oil on the serviceings and they've missed the oil filler hole as it were and it's spilled down the side or is it a common issue for leaks to appear around that area?
Cheers Pete
