Web cam solid lifter failure? Options

[mate914]

As I was recently doing a jug and slug transfer on my 2056. As I rotated the engine one of the lifters slid out and landed in the box. When I picked the lifter up it appeared to have come apart, I push the part back down in. Are solid lifters empty in the middle, no springs or ball like the hydraulic?
1. Should they all be replaced?
2. I have a brand new set of CB performance solid lifters, will they work if same spects?
3. Should I just replace that one.
4. I kind of wanted to show up for Carlisle in a Porsche.... I have faith I can accomplish this. Especially with all the knowledge on this 914 world.

Some are solid, some are two piece, some 2 piece have a c-clip, some have a lube hole, some don't...

Simple test to see if they're worn:
New or good condition the face should be slightly convex.
Place two lifters face to face and hold them up to a light. If good you should be able to see light on the outer edges. No light and IMO they're done.

The lifter in question just put it back together, it doesn't need a clip once installed the loose part is trapped and not an issue.

-Using new lifters on an old cam is a crap shoot, it will either work or the cam will go flat.
-If the old lifters pass the test above use them.
-Don't replace just one, replace them all.
-Keep used lifters in order.
