I started having some noise when idling or driving and then pressing clutch (releasing load from engine) its not much like grinding, but like low pitch humming, i am pretty sure its a chain however if you think it might be something else let me know.

My main problem is engine shaking on idle without load too much no matter if i have set high idle rpm there is still too much vibrations.

For chain whats better brand to use BECK/ARNLEY, CLOYES or SEALED POWER for chain, tensioner and guiden?

One is pretty much good as the other, just make sure the one you get had steel guides, not plastic.
