I don't expect you to diagnose it, just sitting here by myself all night and this morning thinking about it and wanted to bounce it off someone.  |
Sometimes lifters bleed down at idle and clack a little bit. This may or may not be the case with you car. Take the engine from idel up to 2000rpm and hold it there. Does the sound go away? Is it just at idle when you here the lifter or valve train clicking? If you take the engine RPMs up slightly and it goes away, its probably nothing to worry about. If it gets louder proportional to RPM get it into the dealer like right now and have them check it out. More than likely its nothing but its better to be safe than sorry
