how much does it typically cost to repair the lifter? on 2005 Chevrolet Trailblazer

Our trailblazer has a constant ticking noise under hood that is very loud and shakes and vibrates when start up car and at stoplights...been told a couple thousand to repair the lifter.

You don't repair lifters, they all get replaced at the same should just have it gaskets and seals through out the entire engine.that way you KNOW everything is new.
