Are my BOVs shot?

I have a recent ticking noise. I think it's my BOVs. A few weeks ago I cleaned my DCI. I must have knocked the vacuum line from the intake to the BOVs loose. A few days ago I got a ticking noise that seems to originate from them. I took out the DCI and found the loose hose. I reconnected it but it still ticks.

1. Do bad BOVs make a ticking noise?
2. Can I damage anything if they're not functioning properly?
3. Can I do a temporary fix? I plan on replacing them in a few weeks anyway when I get paid.

They are stick, have 226,000 miles on them. The waste gates are leaky and shot. I'm not making any boost at the moment and wasn't before. I just want to limp along for a couple thousand highway miles till I can replace them and not cause sny damage. I think one or both may be stuck open. Would this happen if I loose vacuum? Maybe hose is leaking.

Thx
