I (and alex) did an oil change on my car around early June, and we noticed a small grinding/rattling noise which seemed like it was coming from the very front of the engine---i don't remember hearing it before the oil change---all the internals in my engine are new (on a side note this probably was the reason why I beat harry when I raced his dinan ///M also). Many have suggested that I shouldn't worry about it that much, and that it may go away. I didn't worry about it until today while washing my car I became double curious about it, fearing it could be bad. I have only driven the car about a thousand miles since then, the noise hasn't gotten louder or anything. I have asked a regular mechanic who is a friend of the family (non-bmw mechanic) and thinks it may be because I switched synthetic oils (previous owner used something else, I went to 10w-40). He said switching to a different grade may make it go away. He also said I may need my valves adjusted possibly. I'm taking the car to a trusty bmw mechanic tommorow morning to find out exactly what it is. Any ideas gentlemen? Fire away.
