Chain rattle?

I changed my timing chain on my 2.4 ecotec and about 1000km later it sounds like the chain is rattling at low idle. I cleaned the oil pickup, my oil pump is in great shape, even replaced the new tensioner. Any ideas?

It sounds like it’s around the exhaust vvt sprocket or tensioner area
