Hey there, i just got a 07 civic Si on the 11th of october, got 1500 miles on it now.. When i was driving home today, i got stuck having to go through a puddle deeper than the curb id say.. after going through it, i didnt notice any problems at all, didnt sound wrong or anything. when i got home i popped the hood while it was still running, and it has a constant lil "click click click". like a chatter from the engine. cant really hear it with the hood down.. I dont remember if it always sounded like that.. Im thinking its just normal... I figure if something was wrong a light would come on? SO is this normal?? should i have it looked at? thanks for the help
