Hello all, I am hoping to get some help identifying an engine noise that has appeared over the last month.
Above is a video with the noise, it is coming from the drive belt side of the engine and near the back. I have had the main crank pulley replaced recently to rectify another issue but alas it didn't solve this one. And now I'm noticing a change/roughness in the engine idle too.
I recon it's an idler or tensioner but could be wrong. The MOT is due in November and if she needs work then might as well ask my mechanic to have a look but a bit of research before may help in the long run, or allow me to fix the issue myself.
Thanks in advance for any suggestions.
