Interesting - I could not compress any of my lifters yesterday - I tried them one by one by putting a pushrod in the seat (lifters in their normal positions) and pressing as hard as I can - zero movement. Does anybody know the specifications of the internal lifter spring?
FYI the engine has not been run for about 10 weeks, so I assume the lifters are bled down...
So the #88958689 caddie, ltx, lsx roller lifter will work in an '89 L98 also? Or would the lifter kit #12371042 be a better selection, considering they are so close in price? Which one would work better w/a cam w/.539"/.558" lift? Thanks,
Rich K

I tested a couple today - the movement inside the lifter is visible when I added half a turn of preload. Didnt mean to hijack the thread - thought it may be useful in future to add this info.

I had two in my hand on the bench.
one would compress, not much but it did compress, with just a little pressure.
The other would not compress no matter how hard I pressed.

Perhaps it's a solid lifter?
Are you sure it isn't still full of oil? If lifters are full I don't think you can push them in by hand. Try standing them up and soaking them overnight in a jar of oil, then see how they act in the morning.

That practice is specifically NOT recommended by every engine parts manufacturer I have ever seen address the subject.
