the last guy i let work on MY ENGINE overtightened my oil pan bolt now its really stuck . Whats the best repair strategy

 

Vicegripps? If not you could weld a bolt or nut to it and get the old one out to replace it

 

If it is rounded off, use the next size smaller socket or even a standard on it, beat it on with a hammer.. Might mess the socket up, but should work.. Or take a chisel, hammer it in the counter clockwise direction towards the out side of the bolt.. Or like stated you could weld a nut to it

 

Is it the thread or head? I dont really know how you strip one.. but, if its the head, get these (sold at Home Depot or Lowes)

 

Get it up to operating temp (or use a small propane torch)and use this to get it out.

 

No need to get up to op temp. Its only a 10mm head and TQed to 18ft lbs (if installed right). hell, if its the 2 small ones, theyre 8mm and 132in lbs.

 

Why not play it safe and get some heat in it first, makes it much easier. No use breaking the head off. A little head on a big bolt will snap easy if its seized that bad.

 

True story

 

Preeeettty sure the OP is talking about the oil pan plug....

 

Heat will definitely help, run it and get it good and hot. I'd have a new drain plug ready to go though, and hope that it isn't cross threaded, or you'll either be drilling, re-tapping, or replacing the oil pan. There are oil drain plug repair kits available, not sure if they work on aluminum pans or not though...
