you bet, I changed all of the oil tubes on that bank, and have gone over them again to make sure that none were blown out. thanks for the imput, I was just hoping that I did not have to remove or move timing chain out of the way, Some techs say that the lifters have factory shims on them, is there any truth to this, I am not too sure of what kind of bee's nest I am getting into.?? Can the cam just be lifted up enough to get the problem lifter ou and the new one installed?? Ben
