stevenh, this is a REALLY important thing to get fixed, if ur tensioner's give up (which could happen at any time), you're chain will slip and ull get piston valve contact, ruining the engine. if you need the guide or part no's for doing this urself pm me. but after 73k considering mine has just done 75k on n'plates, i'm unsure about the tensioner's being a problem at this time. but get it checked, better safe than sorry...
