Hi to all, just signed up and looking for some info if anyone out there can help. I have a Lupo Sport, 16 valve, 100 HP, I believe it has the AUB engine? Anyway my question is how can I get at the crankcase end of the breather system? I was getting "mayo in the airbox and breather hose, now I have traces of oil in there but no mayo?? It looks like a black plastic box is fitted at the crankcase end of the breather and it looks very inaccesable. Whats in there and can I service it/clean it/unblock it or whatever is necessary! The car has done 70,000 miles and has always used between 1/2 ltr and a litre of oil per thousand miles. Almost all of this is motorway driving(between 3 and 4000rpm. Any suggestions that wont involve a visit to the dealer??
