Hello to UK mini folks, from Canada , my first post here
My problem; what sounds like valve train noise , just a rattle [ from the frontish area ] that makes my car sound like a diesel , not dangerously loud , just an annoying background noise [ my other mini is smooth and quiet by comparison. ]
i tried to get rid of it by installing a new cam, followers, roller rock , timing chain , from MED Eng. but the only difference it made was to make it quiet at idle but as soon as i move the car in gear it appears . I now also have a 123 ign. and its the same with all timing curves . Its also no better or worse driving at any speed.
i did find that the Nural pistons had some scraping on the skirts and the only other thing i can surmise is that the followers are a bit tight. ???
thanks for any help ,
