The balance chain tensioner is a weak spot on the engine mine snapped on my old car and I noticed more vibration due to the balance shafts not being quite right and did the chain. When I saw the bottom of the crank case the chain had been rubbing against it. I don't believe the chain is a lifetime item due to the extra power they tuned the engine to from its Saab origins.

Mine is all done and driving really well now, really quiet and the power delivery is much better than previous. Happy days
