    I ran a tap into it and bought a new plug and some nylon washers. it leaks worse now. apparently i've milked it long enough.

    so i take to to a machine shop or welder, right? which one?

    What do I tell them? "Weld me in some new threads, fool!"?

    i could helicoil i guess, but i've seen the newly welded in threads/nut/whatever it's called and they look strong and professional, the way I do stuff on my truck.

    thanks...i tried the search but all i got were transfer case and transmission questions...

    You should be able to put a new oil pan & gasket in for $50-100.

    Well i thought about that welding a nut idea but then any metal debris will collect around that nut on the inside of the oil pan. I suppose I could weld one on the outside of the drain hole...

    I didn't even consider buying a whole new one, usually I'm all about fixing the old one and then keep on truckin'. It sounds like a new pan is in order if the cheap price is true, since that will save me down time with my oil pan off.
    thx for the info dudes!

    See. That is a much better idea than anyone else had.

    I did the same thing a couple of years ago. I got this new plug from NAPA, but im sure that most auto parts stores have them. It is a threaded plug that will cut new threads into the stripped plug hole. It has a nylon ring that seals it when you crank it down. Inside of it is a smaller drain plug that threads out the other way. It was less then 10 bucks. Good luck.

    don't feel bad, you aren't the only one to strip out some threads... at least you didn't strip them out on your engine block :doah:

    Piggyback drain plug..

    Thats a "Piggyback" drain plug!--I've used them lots of times!..there are also a dozen or so others that are rubber expandable,single,double,or triple oversize steel drain plugs,etc..--lots of options other than pulling the pan or changing it..cheap too,less than 10 bucks..

    One guy that came in the parts store was looking for a 14mm drain plug--someone before him stripped the 1/2" x 20 hole in the oil pan--and tapped it to 14mm(about 9/16!) and screwed an old sparkplug in it!--he was going on a long trip,and feared the spakkplug might get snapped off!..I sold him one for an Audi--it fit perfect!..

    Just pull the pan and put a new one on do it right the first time so you don't have to do it again. I give this advice cause the pan is so easy to pull in a chevy truck if it wasn't I would probally go for the other plug fix idea. :D
