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 tried the shop vac to the oil filler once and only once on an oil change on my old truck, they say it holds the oil in the engine with the drain plug out and it does, what I didn't expect is after I removed the drain plug then turned off the shop vac...
FOUR gallons of oil had a HEAD PRESSURE COMMING OUT!!! /ubbthreads/images/graemlins/phoney.gifabout three gallons did stay in the drain pan and the inside of the hose for the shop vac will never rust (Yea I know its plastic) FUMOTO FUMOTO FUMOTO
