The vibration problem is solved. It was the exhaust system , proberbly hitting the crossbar below the exhaust pipe and cardan shaft. A new ruber piece , looks like an O-ring holding the middle muffler a little bit higher up solved it. Cost aprox 3 €
Still haven´t found where the oil leak is . Right side / back side of engine or cylinder head , near right ignition distributor.
