think i'm going to have to bite the bullet and change the tappets in my X20XEV (95 cavalier Sri) anyone advise on this job i'm lead to believe its a cam out job to change and a royal PITA obviously its going to be a timing belt and tensioner as well when cams are dislodged anyone suggest anything else to try and quiet down these noisy tappets? btw it seems to have gotten worse since i had it flushed and changed the oil and filter. thoughts guys?
