Hi there is a slight difference with replacement chain tensioners but awkward to see the tensioner head ( just a hex bolt) is just that on the original, on replacement ones they have either a punch hole directly in the centre of the head of the tensioner or the head has a raised circle area on top. I will try and dig out some photos and post them. What I think is more important is that even the new parts are fickle if the oil level is allowed to drop too low, and these engines generally use oil, the tensioner/chain can fail.
Possibly due to the fact that Peugeot won't admit to the fault in the first place they don't advertise the fact that the jobs been done on service histories, I got a printout of the work done when I had my kit replaced.
When looking at a new car make sure the engines flat cold and listen for A rattle from the offside part of the engine this may quieten down within a minute or so on chains that are bad it will sound like a diesel!.
What I would do is factor in around £600 into the cost of the car for possible future chain replacement.
Good luck :thumbup:
