Bad hydraulic lifters -- How can you tell?

[joselu43]

I am in the process of replacing worn rocker arms and I am wondering about the lifters. According to the manual, you check them pushing with a hammer handle and making sure they do not "drop too fast". Mine do not move at all ... does that mean they are OK or just the opposite?. I also tried "Herr Fuchs finger test" but I cannot make sense of it. The rockers are out now, is there any other way I can check the lifters?
Your advice/opinion will be grately appreciated.

Also, does anybody have a lifter go-no-go test gage that you would like to sell/rent?
(I tried in the tool rental section with no luck)

Thanks.
