thanks for the in-depth report , it helps a great deal , i will follow your suggestions they are very good . i have no leaks at the vacuum pump now as i swopped my febi brand for the genuine pierburg so its dry now , i have a fairly clean engine i do wipe the top area valve cover etc , i will go under car next week weather permitting and do as you suggest , a D24 friend had a look before this happened and thought he could see a tiny weep on the lower idler pully bolt inside the cam belt cover said he had a leak there as that bolt goes through into the engine ,he repaired /sealed his ok .have you come across this issue ?
thanks again V8 VOLVO
