Hi Guys,
The car in question is actually a golf gti but it has a CDL engine fitted.
Recently it had a bad misfire throughout the rev range, and ran on 3 cylinders, however this was fixed by replacing injector 3 and all 4 spark plugs.
Now on tickover its got a very slight hiccup/misfire.. Not enough to cause the engine light to come on, and it drives and boosts fine.
There is also a metallic rattle coming around the 2.5/3k revs, I thought this was down to a possible failing timing belt tensioner, so I've had the Cambelt Kit done along with the water pump and the issue is still there. The sound won't come through on a video as there's too many other sounds coming through from the engine.
The fan belt tensioner looks like it has some slightly play, are they meant to have any play? And would the aux belt and tensioner make a noise from applying revs?
Any advise would be appreciated.
