Hi:

When I bought '86 Westy a couple of months ago, the oil had just been changed. I tried to change it again, but to my dismay, the drain plug is unservicable. It's pretty "round" and I could not remove it. I suspect that the previous owner or his mechanic has been draining the oil using that larger "pressure relief" thingy, since I don't think it's possible that the proper plug has been removed anytime in recent history. Given the plugs recessed nature, I have not been able to get a hold on it with any of the usual tools of ignorance...I've probably worsened the situation.
What can I do?

Tom
