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

This was the truth.

In keeping with James response, the absolute cheapest way to drive your car (if the end of the IMS isn't trashed as he indicates) is to replace the bearing and flush.

Second cheapest is a used motor of unknown origin and history

3.6 or 3.8? You must have deeper pockets than I do. Going rate on those engines (again, unknown history and total crap shoot) is $10k all day long. Check that your ECU is compatible with the engine before even making that decision.

Not sure if rolling up your sleeves and doing it yourself is on the list of possibilities. I did all my own work and spent less than the unknown used option. I'm just a retarded engineer and managed.

That looks scary. Thanks for your input.

The 2005 may have the large diameter IMSB ? Check with other Forum members. Makes a difference because the only way to remove the large IMSB is a total engine dismantle.
There is a hack method of boring out the back of the crankcase halves but there is not much field experience/results from this new method.
Like James and Flaps ,I have just done a rebuild and it is stunningly expensive to do correctly. Lots more time than a regular engine,very specialized machine work and very little factory documentation to help.
Just be aware of what you might be getting into before you start. I am familiar with Jaguar engines and found this M96 very exacting!
