If it's a tensioner which lost its tension then chain will be loose slightly.
So in the morning before you start the car, open your bonnet and start the engine. Now during the start up you will hear a knocking noise for a second or 2 at the most, thats how we determined it is a tensioner. But also to be double sure I've had one guy listening back of the engine on the left side, and one at the front of the engine right hand side.
The chain and tensioner and chain is just behind the metal cover so its kind of easy to determine if it is a tensioner or not.
And if it is a tensioner then camshaft is out of position slightly.
