Q: Odd sound on start up
I've noticed that whenever I start my engine there is an odd grinding / shearing sound for about a second. It sounds very similar to Startup 1 in this video. It only happens on cold starts. I tried starting my car after I got home yesterday and didn't hear the noise. From what I've been able to find, it seems to be related to the timing chain, but I'd love to hear your thoughts and input as to what other possibilities it could be. Would you also be able to give me estimates / quotes for the various repairs that could solve it as I know it's best to tackle this early before more serious damage occurs. The other day when I was leaving for work I heard an odd grind when I was backing out of my parking spot, but I don't believe this to be related.
