Alright so my stock lifters where starting to tick so i replaced them with some brand new LS1 lifters and now i have a damn tick on the 5/7 cylinder. What else can cause a tick? They are brand new comp cam hardnened pushrods so i know that they cant be bent. And ive adjusted the lash on them so many times hoping the tick would go away and it doesnt. I dont want to take the manifold off to replace the lifters again if i dont have to so any help would be great.
