Its the one between the oil pan and the drain bolt. It is supposed to be one of those copper washers but they used something else, either rubber or some kind of fiber one.
Changing oil gasket without draining oil?
I have a minor leak that spreads across the bottom of the oil pan caused, I think, because the wrong type of gasket was used at the last oil change.
The place that did it said that they would be willing to change the gasket. They said they could do it without draining the oil by applying a vacuum to the oil fill tube and I guess blocking off the dip stick hole so that the oil doesn't come out while they change the gasket
Has anyone ever heard of this being done successfully? Can the vacuum cause any damage to any systems in our 7.3 engines?

I kind of agree with you, it would be interesting and if they blow it I get some fresher oil.
But isn't there maybe something in the oil system which could be damaged by all the pressure that would be generated by applying enough of a vacuum to hold in the oil? It seems a little scary. They say they have done it on cars, but there they only have to hold back maybe 5 quarts. I would think maybe the reverse vacuum pressure it would take to hold up 15 quarts could have an adverse affect somewhere else in the oil system. No?
