Seized oil pan drain plug

[Gatorbait]

So the drain bolt on my oil pan is seized. There's one on the side so I can work around it but it's a pain in the ass to suck the rest out. I need an oil change soon so I figured I'd remedy it on this go around.

I'll probably just leave the bolt alone and tap/die a new hole. Anything I should look out for or NOT do? I'm thinking of dropping the pan just to clean it out real good and check everything out. is it as easy as I think: drop it, clean it, drill it, new gasket, install? Am I overthinking this? lol

if you are going to drop the pan anyway, I would see if I could find a new pan.

Or it should be a hole lot easier to repair the damaged plug once the pan is off, that's what I would do. Once the´pan is off and clean hit the plug hole with a propane torch, the aluminum will expand faster than the steel plug and release the hold on it. Chase the threads and install a new correct drain plug.

Now would be a good time to install a Fumoto oil drain valve, then you won't have to undo a drain plug ever again. Well worth it.

Personally, I am a fan of magnetic drain plugs. They capture and hold anything from micro to macro ferrous particles and keep them from circulating and doing damage. Used them on race bikes and numerous cars over the years.

**THIS**. I had a valve on my hotrods.. no more droppign the drain plug in the oil drain pan!!

ive had good luck getting a stuck bolt loose with a wrench and tapping on the wrench with a hammer.. just a long wrench will break the welds everytime on the bung. but tap-tap-tap. has gotten me out of trouble more than once..
