Did a 280 mile trip in the type r yesterday, all seemed to be ok, noticed as I was driving back through town a noise that sounded a bit like a heat shield rattle. Got home and opened the bonnet and it sounds like it’s definately top end noise and possibly from the timing chain side. Is it easy to check if the tensioned has packed up or is not working properly? Still drives fine, just the noise. Oil levels are all ok.
