Thread: freak T seals..?

300tdi engine
T seals replaced with rear main seal 6 or so years ago
flywheel housing is dry in drain hole, but sump has started leaking.
took sump off and resealed with the sticky non hardening gunk, unfortunately leaking even worse now

I found it a bit difficult to put the sump on as the T seals were weeping a tad of oil ( on the bottom where the sump conveniently bolts onto ) so I waited a few days and made sure to degrease before bolting the sump on, but something went wrong and I need to reseal again soon.
Thought I might do the T seals while its off again if I can..

Questions:
What sealant should I use on the sump if I leave old T seals in (... previously used the black silicone stuff, this time the non hardening stuff)
and could I remove rear main bearing cap in situ (engine & g/box) to replace the T seals, or will I get myself in even worse trouble with the rear main seal....?

Thanks in advance!

Thank you - will have to try black permatex again...... it is literally pouring out oil at the moment
otherwise it might do for an interesting T seal experiment... can't get any worse
