Put the new timing chain in.
I know of the same loose timing chain issue on a caravan. Recommendation was only drive it back and forth to work 4 blocks away.
Their kids took it on a road trip to Duluth MN on I-35w, 70+ miles per hour.
Blew the timing chain half way there, had to leave the van up there and junked it out.
The price of new vehicles it's a no brainer, put the new chain in.
