Hello and welcome ... Obviously didn't spot this when you originally posted. FYI, "c rossover" becomes "crossdresser" "s hite" becomes "marmite" "c rap" becomes "carp" "e arlybay" becomes "prototype" "o range" becomes "Jaffa" etc etc ... Never ask or reply to "What oil do I use". Never ask for opinions. You will get them. Never ask people not to offer opinions. You will get them. If @davidoft doesn't have the part you need, sell your bus. If you don't understand the technical info on offer from @mikedjames ask @Barry Haynes ... (not) If you have plumbing skills, keep quiet about it. If you don't have plumbing skills, pretend that you do. If you like quirky French classic vehicles @Merlin Cat will be your NBF. If you fancy a sunny break away, try Barnsley (allegedly). If you prefer a trip to East Grinstead avoid the taxis like the plague. If your bus breaks down try to make it happen on, or near the IOW. That'll do for starters. The rest you'll learn the hard way soon enough
