Glen,Glen, the oil is coming out of your Center Swivel. The top seal is leaking the oil into the swing tub and then coming out the turntable. If you can get in there, take the rubber boot off the center swivel, pry it up and you should see oil there.
I have the same problem with my 1994 Hitachi EX60URG.
The answer you received is very informitive. "Glen, the oil is coming out of your Center Swivel. The top seal is leaking the oil into the swing tub and then coming out the turntable. If you can get in there, take the rubber boot off the center swivel, pry it up and you should see oil there." The problem is how do u get in there. I have removed all the access plates from under to no avail. Does the entire top have to come off the machine? Can the "center swivel" be dropped out the bottom?
