So I sold my wrangler to buy this Yota, I also have a 99 4Runner so I was excited at the relatively low miles for a 5vz-fe. I sea-foamed the engine today, didn't get much smoke. Also changed the oil and added Lucas, I'm gonna try using mid grade gas my next fill up as well.
Any suggestions on what could be causing this knock? I'm gonna try to get it into a shop soon.

 

When did the knock start?

 

Just bought this truck a few days ago, not sure when it started.
