Well I found a puddle of oil under my 1993 F150 with a 4.9L straight six cylinder..I got to investigating and found that at the bottom of the oil pan near the plug there was a very small hole. So I ordered the new pan and gasket and then got to reading some books about the removal of one..it sounded a little more complicated than I had planned. So how hard is it to change one? Any tips will help. Thanks.

Here is a thread that was a about the oil pan removal on a 300-6.

If the hole is in an accessible place, it is also possible to reliably plug the hole:

* Drain the oil
* Wire-brush the pan in the spot of the leak, with a cup-brush in an angle-grinder, if possible
* Identify the point of the leak, put a large center-punch on that point and hammer it in until the edges of the hole are solid metal.
* Clean the pan with brake-cleaner in the area around the hole, making sure it is rust, grease and oil-free
* Find a self-tapping screw or bolt slightly larger than the resulting hole; a bonus if you can find a screw or bolt with a washer-flange under the head.
* Mix up some JB-Weld (I used the quick-set version), and spread it around the hole and on the threads and underside of the screw-head or bolt-head.
* Drive the screw or bolt into the hole until it bottoms.
* Smooth over the head with more JB-Weld.
* Once the JB-Weld sets, you can refill the oil pan; if it leaks again, that means you missed a spot; just repeat in that one spot.

It took a total of five screws and/or bolts, the largest being 5/16", to seal up my rusty pan. It is, however, now leak-free.
