started about 4 days ago but it has been doing it for a miniute
my lifters are ticking in the back and two of the lifters were very loose on 2003 Chevrolet Impala
I think you mean rocker arms. The lifters are on down in the engine! Need to get a mechanic to check it out for worn parts. Hard for the average diy'er to tell. Also, adjustments are critical. Now you may be capable but no way for me to know that.
