I can't get the bastard undone; I've got a new HEL one still in the box because I can't get the old one out. There's nothing wrong with it, but I was replacing the brake hoses and thought I'd do that one too.Clutch pipe isn't too bad to do. Remove the pipe from the maf to the turbo and you can see it, I got an updated braided one on mine now off eBay, probably cheaper than original Nissan one.
