IMS - 2rs + freeze plug

I had not seen this link, about halfway through reading it, came upon this:

had not considered the pressure disassembling IMS shaft. Will have to think that one through. At first blush, I don't think the pressures will be high enough, but need to test exactly how high the pressures might be experimentally.

EDIT: the last two posts in the thread seem to indicate the IMS Solution uses a "blanking plate" to block air/oil from the ims shaft tube. Sounds very similar to what a freeze plug does, and would indicate that pressure inside the shaft is not an issue.

All I want to do is make the Porsche bearing last as long as a clutch does reliably. May not be possible. Nothing in that thread rules out that a plug might help the situation, however.

I appreciate your willingness to experiment and freely share your results. I wish you best of luck and be safe.

I get where your coming from financially. My car has 133K miles and, at 17 years old, the last nine of which have been mine, I've of the opinion that the car owes me nothing. That being said, if I'm still the owner when the car needs a clutch, I'll replace the bearing.

My math is kind of like this....
Current value of car: $7.5K
Value as a roller (worst case):$2.5K
Spending $1500-$2,000 to just go ahead and replace the bearing seems like very expensive insurance.

Please understand that I'm all for the bearing change with a clutch. I sleep well at night not worrying about this thing although I do find the discussions worth reading.
