Hi there M8

I would like to add something to this post. If you are not sure about the scrach and you must not have been sure as you put a post on here. I would take it in and have it checked as there mybe more to it than the 1 scrach that you can see. Is it worth blowing the Engine and taking it back and having to try and sort it out, or would it be better to take it back before you run it ?
