LEM Chamber Vacuum issues

[MacAttack]

I have been having issues with my MaxVac. When it changed from vacuum to sealing there was a distinct change in the normal sound, and I don't really know how to describe it. I checked the oil from the peep hole in the back and noticed some weird things floating in it. I have drained the oil, I need to try it again once I fill it back up, but has anybody had like a fat or rust looking substance come in the peep hole of your MaxVac?

I'll try and post pictures but it wouldn't let me...

Might need a new v pump, amazon or ebay it

Take apart your chamber vac, pull out pump, install new one.
