rocker cover gasket, bit more involved than 8v versions however gasket is only a few quid and garage wont charge you more than an hour...leak doesn't look that bad to be honest compared to many I have seen.
The leak has been cleaned up dramatically I originally thought it was coming from the gasket behind the coil pack but have replaced this an still she continues to leak.
Few photos of the leak in progress
Although its a small leak its using 2ltr of oil a fortnight
