In standard form they are not adjustable. In theory hydraulic lifters are noise and adjustment free.
Like all hydraulic equipment, they wear. Depending on condition and frequency of oil changes directly effect the longevity of lifters. You could try some products like Nulon lifter free to see if it helps but the ultimate solution would be replacement.
