2009 scion tc 139,000 automatic

Hello, I recently bought a used scion tc. Last weekend the timing chain broke so we replaced it to see if the motor was still good. It still runs and drives but it has what I believe is a ticking lifter just from comparing the sound to YouTube videos with similar ticking. I'm exploring options, should I rebuild engine, get another head, or just get a whole new motor? It is the 2az-fe motor and I heard some people were able to get it rebuilt by Toyota because of some oil burning issue so I don't know if I should try that? I don't know much about cars so any advice and help would be appreciated. Ideally I'd like to keep the car since it's the first car I've bought on my own and really like it.

Do you know why it broke? Was it low on oil?

It depends on the engine conditions. Does it burn oil? How many miles on the car?

You can try but I doubt they do anything for that because I think Toyota offered a very limited time for engine rebuild due to the bas piston rings. 

 

I believe it broke because we were trying to fix some oil leaks on it and we pulled the chain tensioner without knowing and just put it back in without adjusting. Engine didn't burn oil and ran very well with 139,000 miles on it. Didn't overheat or make any weird noise when the chain broke, basically broke at idle at about 700-800 rpm.

Considering the condition of the engine and if you sure that the noise is because of the lifters, I use the current engine.

Would you advise replacing the head or rebuilding it? Maybe another option I'm not aware of?
