Personally, I guess I'd say this is one of those things that you could easily replace when it fails and that the very act of preventative maintenance might be riskier than just letting it fail. Mine is probably original...I'll let you all know when it finally goes!
I think this must be true. The DISA has to be pretty much flush against the manifold for it to be of any use. So the PIN can't fall out unless you actually remove the DISA. It's not really a time bomb.
