Crankshaft cross over tube is loose. What to do?

[ArjanPlomp]

All,

We just had our prop overhauled and were told that the cross over tube inside the crank shaft was rotating while it should not be.

We had a few opinions about this:
-live with it since you have been flying with this for potentially hundreds of hours already (we have 700 hrs on the engine)
-split the case and repair it.
-might as well get the engine overhauled (oil consumption is 6hrs/qt)
-remove the cross over tube.
-fly and check at your condition inspection to determine of the play/rotation gets worse.

What to do?

-Keep on flying is the easy way out, but might not be safe.
-Splitting the case is the 'cheapest' formal solution, but it might be more economical to get an overhaul done.
-Remove the cross over tube.

It's a Superior Engine with Millenium cylinders.

Thanks!
