Wow didn’t expect all this cheers mate
But yes I will definitely get the crankcase breather done! Can I advise on which one is the best on eBay UK as there’s so bloody many
As for the manifold I got the the exact same one u did the x8r cast iron one! And when they took the old one off it wasn’t actually that badly cracked it was about a 3mm gap so must’ve not been that in the first place! I also had a hole in the rear strorage compartment fixed above the back box to no avail also but least I got it done! As for the egr valve I had that deleted and left open on a re map of the x5 but I haven’t taken it off not sure if that is something I should do! It’s weird because with windows open it does it but with them shut it’s spot on
