Usually its easier to be done with head off for the valve springs have to come out along with collets and keepers.
But it can be done with compessed air blown into cylinder at tdc and using a specail tool to push collts down to allow the keepers,springs, seals to come out and replaced...
Usually the "guides" are worn out that allows oil through as well !! The guides are replaceable....
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
