Valve Spring insert This is probably a dumb question, but I'm replacing my valve springs. The ones I'm removing have a spiral coil insert inside the valve springs.
What is that for?
Is it necessary?

No duel spring. Its a thin coil looking thing inserted into the spring. It looks like it might protect the valve from the spring if it broke.
Do I need to reinstall them?
I'll try and get a pic up in a few minutes.

One of the springs broke, so I'm replacing all of them.

That's funky looking, but I'd still bet it's a dual spring. 
Edit: On the borken spring, did the valve drop into the chamber and/or hit the piston? Was the inner coil broken, or did it hold hte valve up?

The valve didn't drop....thank god....
No other damage that I can tell. I just want to put the new springs on the correct way. I bought some 918s with titanium retainers to replace the old ones.

I'm still betting those were dual springs. Somebody who knows more should happen across this later.
The 918's won't need anything in them. Just the springs on the seats with retainers up top, and they are a great spring, BTW.
