I don't know if this is in the right area but I need some help.

 

 

I will supply a link to a YouTube video of the sound of my engine I have had it looked at but the mechanic said it was ok but it sounds like it's running high and knocking and to me it doesn't sound right. I am no way a pro on this so I am seeking advice from the fellow community 

 

I don't know if this is in the right area but I need some help.

 

 

Mines sounded like this for about 3 years, still runs bob on  

Sounds pretty much like mine does - no problems here.
