Does the IMS Guardian work?

[clickman]

Thanks JFP. What I'm trying to get a handle on the results real world users are getting. Are you getting people coming in to your shop with Guardian having gone off?

I'd also like to know, assuming it's the IMS bearing that's failing, how much work will have to be done to the engine should the Guardian go off. Simple as cleaning out the pan and replacing the bearing, or is a teardown required?
