Please help! I am worried about my 1988 Lincoln Town Car I am changing the oil?

happened to me before. i put a screw driver under it to pry gently on it while turning it out, and for a cheap fast fix i bought an expansion plug from a hardware store. the plug is rubber with a bolt running threw it that when tighten it it expands to stop any leaks. take bolt with you so you get the right size.i did this two years ago and its still holding

You have stripped the threads out. Take a screwdriver (flathead) and put it between the oil pan and the bolt and pry down lightly on it. Then take the wrench you were using to try to remove it and work it out of the pan. Once you get it out, take it to the parts store and buy an oversize self tapping replacement oil plug and put it in. It doesn't need to be super tight. Just good and snug. the same for the other plug.

its stripped, basically its chewed all the threads up on either the plug or the sump. my guess is the sump as its usually softer.

to get it out you may be able to use mole grips and wangle it from side o side or you may have to take the sump of and knock it out from inside, once its out you can use a tap and cut the threads a size bigger and put a bigger plug in

well its what we call striped and not much you can do about it othe rthan replace it but first try and pry on it while turning and hope it comes out so you can buy a new one
