Well as described in #4 there's a spring in the tensioner to supply tension when the oil pressure is not there at startup, and if the spring has gone weak, then there's no tension at startup.strockus said:The only reason I feel like it might not be the tensioner is because if it was presumably it would rattle on every start up but it only rattles when the oil is out of the engine which is after the car stands for 6 or so hours. That is just an ***umption though as I am not a mechanic.
I don't think it's possible to tell the difference between the two types of rattle from the driver's seat, you need to stand at the chain/cam end of the engine when the car is started, from what I can hear in the youtube VTC videos , the VTC noise is louder.
