1. as said, there are 3 different IMS shafts available [B]and they are different in detail

The only part that would need to be the same would be the tube size for my test purposes. Would that be different on all 3?

2. you have underpressure in your crank case.

True, will have to account for that with my testing.

3. the simple freeze plug - in my opinion - can start moving. That is why i said come up with something more sophisticated.

I want to test just how hard it is to move a freeze plug in an IMS shaft, so am going to install one in a test shaft and try to get it to fail. Sometimes the simple solutions are the best, especially if when tested they hold up. I think any other solution will either be a) not as strong, or b) impossible to remove. Freeze plugs are time tested as very strong, and possible to remove.
