opinions on knocking sound?

any opinions on this knocking sound. sounds like its in the upper front cylinder but to me it doesnt sound like the acct, I've had the acct apart many times and put in toc but it broke and switched back to my originals with a little extra tension on them. probably gonna do the mcct conversion and hope its not something else. she runs fine other than this knocking at idle, seems to go away more with higher rpms.

Has the same exact sound and poured seafoam in gas tank and in oil. no knocking/ticking sound anymore. At first it drove me nuts I thought a bolt or nut was loose, or metal knocking on something.
