my car makes a loud noise when i first turn it on (cold) on idle then gets quite?

i have 2002 ford taurus with 215,000 miles on it
when i first turn on the car in the morning its really loud then when the car gets to temperature it gets quite
then while im driving the car makes the same noise when i hit the gas and it get louder with the more gas i give it
makes the car scary to drive i dont want it to break down

I believe its the lifters that are making this noise but not sure also is there anything i could do to make it stop?

pretty normal for a car that age and ks on it when the noise doesnt go away when it warms up thats when its a problem
