Hello friends,
I'm trying to locate knocking noise from the engine,
So far I checked crank bearings and nuts, i also replaced timing chain and checked tensioner ,
But I can not find the knocking.

I also checked the balancer and discovered a kind of free play (video attached)
dont know if that's ok or not,
what do you guys think, is this normal?
