Re: Weep Hole Drilling Video
No definative data. All this does is give a leaking slave cylinder some where to dump the fluid besides into the clutch. If you use it as a preventative measure then you need to inspect the hole periodically for evidence of leakage. At least when you perform the procedure you will see the condition of the slave and the rear tranny input shaft seal.
Prior to this there was a recommendation to replace the slave @ 60K. This was one engineer's idea based on the small diameter throwout bearing. The failure of this bearing will cause the slave cylinder piston to spin and destroy the seal. BMW, of course, says nothing on the matter.
