im adjusting my lifters right now and 3 of them are soft/spongy and the rest are rock solid
the car has not been ran for a week
they are stock replacement about 2-3 years old
are they toast?

I adjust then differently but yes use a wire gauge feeler gauge and check for .020 tho lifter preload. You can get away with up to .060 preload with some setups FYI
