:help :help My 95' 525i (140K miles) is making a slight "diesel" engine type noise (louder when I'm idling - a little less when in motion). I was told that my timing "chain" was grinding against something and that I needed to replace the chain (also was advised that it may just be a tensioner for the chain). Any ideas? Thanks in advance for any knowledge and help. (You guys are pretty good on this forum and a novice like me certainly appreciates it). Also, I'm getting ready for my first oil change - should I go synthetic? Should I go with a certain oil filter? Is it relatively easy if I do it myself? :confused
