There isn't a gasket on these engines, they just use an anaerobic sealant (and o-rings around the spark plug holes). It technically isn't a rocker cover either, as it houses the camshafts (therefore known as the cam carrier).

As it houses the camshafts, the timing belt has to come off anyway (once you take the bolts out, the cams will be free to move). It makes sense to stick a new belt on it.

Just make sure the garage uses a flange sealant that isn't silicone based (use Loctite 518 for example). Most garages that don't specialise in these engines probably won't know about this.

The sealant and the 'O' rings form the gasket. There just isn't a physical gasket for example made of cork. The sealant and or O rings can still fail and have to be cleaned off and replaced.
