I'll by confessing up front that I don't have any experience with newer Northstar engines.
Now this particular engine looks clean (how can it not with the admittedly nice plastic cover?) but there is a slightly audible ticking coming from the drive belt near the center of the engine. Other than that the engine very quiet. Is this slight sound normal? Am I concerned for nothing?
Regarding this noise, the sales manager though this sound might be possibly be coming from a high pressure direct injection system, if this engine had such an item. Good guess on his part, but does the 2011 Northstar engine have a direct fuel injection pump in this area (top center of engine)?
Last new guy question... what's that belt near the center of the engine bay going to?
