In this thread today:
- E39 (1997 - 2003) > Engine code po171

Paul kindly showed how he fixed his M54 rough idle with Permatex around the DISA valve o-ring.
- **Rough Idle**p0174 and p0171**Vacuum Leak**ALL FIXED

It's likely he was unaware of the DISA o-ring source at the time of his rough-idle P074 P071 DIY ... so I ask this question (of him) and of the tribe in general.

QUESTION: Knowing that the source exists for the M54 DISA o-ring, if you had a leak, would you 'still' use Permatex or would you simply replace the o-ring unlubricated?
