Lifters tick for a couple of and varnish accumulates in the small oil hole and results in one or more lifters not being able to pump up to the proper oil pressure,resulting in a metal on metal tick.If u change to solid lifters,they will ALL tick.A good potential solution is change u r oil to a 5w-20 put 1/2 can of Seafoam in with the oil and 1/4 can in ur gas tank.Run the truck for 500 miles and then change oil again to whatever u r going to run permanently and put the remaining 1/4 can of Seafoam in.This will clean the top end pretty well and may eliminate ur tick. without engine repair.BJ
