Hello there i was wondering.. Im a mechanic but i had someone else replace my timing belt/cam seals/water pump/ lower main seal. Ive put maybe a 100 mi on it and now im hearing serious metal on metal aound from what sounds like the cam seals or under timing belt cover.. It started out only doing it every few rotations but has become constant.. Im thinking maybe its a bad water pump bearing or the cams were not seated right? Any ideas anyone... please feel free to move this thread.. - - -
