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?

Spongy or not put about .020 preload on them

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

are you loading them up with oil ?

1/4" drive on the oil pump ? run em so they are tight ? then adjust rockers ?

i took out the 3 bad lifters and soaked them over night and they were still soft and i even tryed pumping them up submerged in oil

so i just found 3 lifters from my backyard and ima soak those tonight and put em on tomarow morning
