i have a 07 frontier 4 cyl auto. when engine is cold i hear a tapping noise for about a mile till engine warms up. does this indicate a problem?

Has it done it from day one or did it start after an oil change? Has the oil been changed since new? How many miles now?

i noticed it about 1000 miles, i had the oil changed today,same thing, after i let it sit until it got cold again, thank you.
