if you are just replacing the lifter than you dont need to worry about removing the valve srping retainers and dropping the valve. the rocker arm assembly will remove as one unit. be sure to take the timing belt off first. also be sure to plug all oil drain ports with a shop rag because when you pull the rocker arms assembly up all those lifters are going to fall out. when putting the new ones in use some clean axle grease. just take a bunch and shove it in the end of the rocker arm then push the lifter in.


good luck.
