hello peoples im not too good with the forum thing so bare with me

i have a 2007 acura tsx auto that makes a bad rattling noise during a cold start. it only lasts about a second before going away.
the oil is good im using mobile 1 5w 20 full synthetic

i had a 2009 accord coupe 4 cyl that had the same problem and it ended up being the VTC actuator and got it fixed before the problem got any worse. i was talking to a few of my friends including a mechanic and said that it might be the accessory belt that maybe making the noise even a bad mount somewhere. i doubt its that and i think it might be the same problem i had in my accord but i cant find anything on the internet about this issue and the first gen tsx only for the second gen. i sold my 07 TL and thought that this car would be a way out of costly m/x but its not looking good so far and just might give up on Honda. i can record a video of it and post it if you guys need to hear it


where do i start with this car?
has anyone had this problem or heard of it?
do these engines have this problem in common?
can it be something else?
is this hurting internal components?

looking for help not douchebags
