I do hope no destruction occurs !

1) Freeze plugs commercially available would seem to be .3mm or .01 inch interference. However since they are sheet metal there will be some deformation.
2) I have changed my mind on this, I think steel plug will hold better and be less prone to impacting anything.
3) am hoping that without the air in the IMS shaft to pressurize and depressurize the bearing, a standard 2RS seal will be enough to make the bearing last as long as a clutch reliably. Pelican parts bearing is rated at 40k, plan to pull it at that time to verify if there is any grease left or it all washed out.
The only real risk I am taking is that a freeze plug will cause my engine to explode. I can rule a lot of that out with destructive testing on a dead IMS shaft. I believe there is a previously sold ims retrofit that used a freeze plug, anyone know more about this?
