Alright guys I've got an 04 2.2 direct sri which has developed a ticking/tapping noise which has got gradualiy worse over a few weeks.I had my chains changed recently by the legend that is benny so I can rule this out.I've had an intermitent battery light on but have had this and the alternator checked. I'm sure the noise is coming from the tensioner and I'm sure I can see slight play in the tensioner wheel when the engine is running.Is this the part of the tensioner that fails? Any pointers would be appreciated .
