ENGINE RATTLING AT FIRST CRANK COLD

2009 Toyota Highlander • 29,000 miles

I have a 2009 toyota highlander with a 2.7L engine with 29,000 miles. It has a rattling in the topend after sitting over night cranking in the morning. It will go away after 5 seconds. Lazt oil and filter change. Was 2,700 miles ago and run the correct grade oil in it. What would be the cause?

I figured it was the lifters, but the variable valve actuator system want let it bleed back by would? A faulty selenide or something.

No connection. Why, do you have a code for this?
