Clicking noise coming from back left of engine
I'm pretty sure I've pinpointed what it could be as when i put a screwdriver on the part and put up to my ear, it matches the noise but i cant figure out what it is. The video below is the part i'm talking about, it's the silver cylindrical thing at the start of the video
I've checked the oil and that's as it should be. It has a service history and was last done in November 2015. The oil looks pretty clean as well so I have no idea as to what it could be.
Any help would be much appreciated. Thanks!
