T5 "scare" - lookin for yer thoughts

Gents,
Tonight while temporarily mounting the bearing retaining sleeve (or whatever it's called - the sleeve the release bearing slides on that is bolted to the front of the trans... that thingy) I think I accidentally overtorqued one of the 4 retaining bolts. It's an aluminum case and the torque specs were only 15 ft lbs. I was only temp mounting it because I still have to take it back off and take a hacksaw to the sleeve length - but in the process I felt one of the bolts start to "give" or feel like it was about to be overtorqued - didn't think I was anywhere near the spec yet and was only "finger" tightening them - but, aaaa, with a wrench.

Anyhoo - took out my in-lb wrench (and did the math) - the other 3 bolts I ca safely get 15 ft-lb on, but on this one it starts to slip around 10 or so. I'm thinking that with some black loctite gasket maker (required on the final install) that 10 ft-lbs is gonna be sufficient as the other 3 will ensure the proper bearing preload for the roller bearing on the input shaft (it's a WC T5).

Thoughts?

Makes me a little nervous. The idea of a bolt comin loose and getting munched inside the bell hsg/pressure plate area makes me wanna barf, especially after the nightmare of getting that stuff in around the bell hsg cross-member. I can always just break down and buy a tremec TKO or something, but the only thing worse than spending that much money is spending it after you dumped a pantload into a T5 swap first... So, curious if you all think this thing would come loose, affect bearing preload as long as the other 3 are properly torqued, etc etc.

Any tips for getting the bolt to 15 ft lbs would be much appreciated. Can't think of any off the top of my head - no way to get in the case without removing the input shaft - ok, let me rephrase that - I have NO intention of opening the case. Hope I haven't just shat a great WC T5 by apparently getting to the gym a little too much...

Considered using blue thread locker on the bolt, but it needs to be sealed also and the two don't mix very well (do they??)
