1984 Chevy S-10 Front lifters making noise

My fromt lifters are making noises this started about a month ago, I have never driven the truck low on oil but about a month ago the front lifters are making a noise some days are louder than others also I have lost some of the oil pressure, I drive the truck back and forth to work about 10 miles each way five days a week is there any hope for the truck or should I drive it till it dies also is there anything I can do to make the lifters not make so much noise
