First start in morning can hear lifters tapping for 5-10 seconds then goes away. Whats problem?

What is your question?

When I start vehicle in morning...1st start of the day....lifters are tapping for 5 to 10 seconds and then go away. What is causing this. Its a 2012.and has 89000 miles.

What makes this problem better or worse?

When it sits over night or doesn't run for awhile

How long has your 2012 GMC Acadia had this problem?

Just bought vehicle 3 months ago but noticed it about 2weeks ago
