Hello,

if the lifter is filled with oil and is soft it's gone. Especially if you pull him out of a "running" engine.

There is a spring and ball mechnism in the lifter that in general stops the oil getting out of the lifter chamber. If the spring is worn the ball valve can't work and the lifter will be soft. So the lifter won't be able to generate the correct height for a correct valve play.

If the lifter is new or was a long time out of the engine, just press him and put him in an oil bath (completey covered with engine oil) for some time so he can soak oil in. If the lifter is OK in in general it will work than. Also it will be hard. If it will stay soft something is wrong.

Regards, Markus
