Hi all, wonder if anyone can help, I have a 2.5 V6 Mondeo 130,000 miles on the clock and its making a strange noise, its like a fast ticking that sounds like its coming from the drivers side, its not very loud when idling but very loud when revved, also a lot faster as the engine speeds up, am unsure if the V6 is tappits or shims and could this be the cause?? or pulleys that would speed up with revs, I just wondered if anyone else had come across this and how they remedied it??

any help is greatly appreciated
