Over the past 3 seasons I've had to rebuild the MMI flange pump in my freshwater cooled A4 twice. The symptom is I see oil leaking through the weeping hole and when I pull the pump I see that the shaft is scored and likely the seals are bad too. Bearings look fine and there's no obvious play in the shaft. So what gives?!
After a rebuild, pump works great for a while (no leaks).
Now after two rebuilds im reluctant to do it again without figuring out what could be causing this.
- Alternator belt tension issue? (I just ordered a gauge so I'm not eye'ing it)
- Pump housing no good, needs replacement?
Any ideas?
