hi guys not been on for a wile so i'll say happy new year to all that read this :D ok down to buisness a rattle started about a month into owning my e46 318 coupe it sounds like its coming from the actuall head/block and my own suspisions are the cam chain, had a "mechanic" look at it for himn to say they all do it dont worry bout it but its gotten louder and its now driving me crazy, spoke to bmw and have been assured that they chains dont "stretch" or break so tbh i'm back to square one if its rattling then it must be loose it does get a little better when its warmed up but still rattles on tickover if anyne can shed any sort of light on a fix for this or poss's as to what else it could be i'd be forever gratefull :) many thinks in advance daz ps it has the 1.9 m43819 engine in it if this helps
