Oil leak

What service was it?. Did it have the valve check done?. If so, its common for the rubber seal under the front cylinder valve cover to get trapped between the mating faces. It has to be sat perfectly in line, otherwise it can get trapped and end up with a weep of oil from the location of the pinched seal, which drips down the front of the engine and accumulates eventually, in the belly pan area, usually soaking into the sound proofing material. Main cause is a cack handed mechanic, although it has to be said, its a complete pain getting into the front cylinder valve cover bolts, especially the one right at the front. Other thing that can cause similar symptoms is a leaky oil pressure switch, front right hand/offside of the engine near the bottom. Worth checking that too. Both are very common complaints on the RSV and Tuono. [:)]
