LOL, my 3 g has this metal round thing between the head cover and the air cleaner box, almost in the center but slightly to the passenger side..... its about 2in in diameter. What is it??? It seems to make a ton of noise when the car is running and very loud when first started . I just got the car back from having my shop install a remanufactured head (blew the head) and i think it smoked alittle when first starting yesterday :ugh:
