Got this kit (well, similar) for my 12v. I went to my local dealer first but surprise surprise, NLS

Fitted it, so far so good. Sounds smooth and quiet, but not done a long enough run to see if it holds out!! (Fingers crossed) Only time will tell!!
My original (on 157k) chain/cogs/tensioners were shot (the camshaft toothed cog had a tooth missing so God knows how it managed not to jump. Good job it's a duplex).
