Can any one help or ideas got a 02 v8 petrol !!!! When u start it up it sounds like a bag of marbles till oil gets round it !!! But does not do it all the time !!!!! It as just done 90,000 miles yesterday !!! It's seems though the oil is draining out of gallery's or something it was serviced 600 miles ago where I bought it from and today I've dropped oil and filter to make sure it as and replaced with fully syn oil and new filter and it don't sound any better to be honest !!!!! Any help suggestions please !!!!

BMW Vanos issue I'd say, plenty of stuff on this forum (and BMW forums too)
