Rounded Oil Plug

[DeRocha]

If you search on "Vise grip 7LW" you'll get a bunch of hits where you can find it. The part # is 7LW and as mentioned by BrooklynBay they come in several sizes. The best part is slipping a pipe over the handle and getting a ton of force to muscle stuff off

The link to the bolt extractors is your friend. SK also make spline sockets that will grip rounded bolts, it is an awesome set to have because of all the different types of bolt heads it can grab.

The Craftsman brand now has those type of sockets and also wrenches as well. They are very neat and can take out just about anything (including reverse TORX)

But on the subject... Just get a good pair of vicegrips and clamp them down and tight as you can, then give a good even pressured push (or pull depending on which side your on).

I had this same problem on my room mates car when he asked me to change his oil. Vice grips are great. Just make sure you get a replacement plug before you pull it out

sk is in bankruptcy and will not warranty broken sockets. try to steer away from them.
