heli-coil it. they are strong than the stock and really easy to do. also with the gasket get the new one from ford. the cheap one with the filter WILL leak even if you fix the bolt. i am a mechanic and have ran into this a number of times. any time someone uses the cheap gasket it leaks. i even converted my 95 over to the reuseable gasket whick required grainding the pan to make it fit and i am leak free.
