Hi guys,

Im hoping you can shine some light on what maybe the issue. Bought my A6 2.7 and ran it  for a couple of weeks. But then change the oil and filter on it using quantuam 5w30 507.00. Since then ive got a  ticking noise from the right bank. Sounds a quite light ticking. It appears louder from the centre of the cam cover - possibly injector?? 

You can notice at idle and speed increases with rev. Until about 2000rpm which is when it appears to disappear (or  drowned out)

Just strange i didnt notice this before the oil change, cant see how an oil change would affect the injector.

Thanks in advance!

Common fault are injector washers. They tick when worn . Fairly cheap to fix.

That's reassuring. Any special tools required to change them? 

You need a tool to hammer out injectors... 

Ah OK, a slide hammer

Took the injector readings today and they are as follows 

0.99, - 0.33, -0.38
-0.24, -0.42, 0.38

norm in + - 2.99 , but the 0.99 seem abit high comparing to the rest 

the worn seals wont show on vcsd

 

Yeah I realise the seals wont show, but I was thinking maybe the ticking is one of the injectors. Maybe the one showing as +0.99.

Which is what cylinder number?
