IMS failure - how can I confirm my engine is toast?

[flaps10]

There is where I have to disagree James. My main and rod bearings were heavily worn from those chips and my cam journals (they aren't really bearings in any sense) had some light scratches - thankfully light enough that I may have dodged a lightening bolt.

I do agree that the stock filter is better than it is given credit for, and it is certainly easier to inspect.

I'm also curious how the LN filter ( which I have installed ) is supposed to eliminate bypass since it mounts on the same location as the stock filter. Bypass is usually a function of the oil pressure relief and the LN doesn't touch that.

Apparently the stock filter housing has a spring and plate in the bottom that also acts as a bypass if the oil is cold enough. My rod and crank bearings were also worn, but evenly (not scratched) from 120K of freeway driving. The chips never made it past the filter in my case.
