It's done 128k and had a remap done 2 weeks after the cams were done, it's been done for 2 years now, it has regular oil change probably every 6 months, and service, I haven't done anything to bottom end, do have a slight knock on a very cold morning start up and goes after 10 seconds but recently has been more noticeable, after its reached temp, but is due a oil change, but it's never had an issue till recently with blue smoke, and does smell like burning oil when driving 😕
