My Cayenne S has developed a leak in Banks 1 and 2 of the Valve cover at 80K miles, is this common ? Seems a bit early, low mileage.

The main belt tensioner is also leaking, which I thought was odd too.

Yes, it's common. The valve cover gaskets get brittle from heat. Treat it as preventive maintenance. I just replaced mine at 67k.

Hi, how much it costs to replace it ?
