im very worried. from the cabin it sounds like clicking.. almost in tune with the revs. i've only heard it after driving it for a period of time (mabye a little hard) then while idling i hear the tick tick tick tick tick like in tune with the revs.. ie, very fast. i get out, pin point the sound to the block.. towards the headers is my best guess, but from under the hood the sound isnt tick tick tick, its knock knock knock. so.. i check the oil. its loww.. :S bad sign. i top it up. it hasnt ticked or knocked for the last couple days but i havent been driving it much. any ideas? it sounds like its louder in the cabin than from under the hood! my girlfriend could even hear it hehh thats when u know its loud. the sound worries me, the car only has 6000km's on it. anyone?
