went to change oil on my newly purchased 27 t and discovered the oil drain pan plug's threads are striped. I will be trying to use a screw extractor but if that doesn't work any tricks out there before I take the engine out.

Try a different drain plug. Plug metal is softer than the threads in the pan.

Don't know the thread pitch, may use a chase to clean up the pan threads

William, I don't understand what you are trying to say. If the threads are stripped but the plug is still in and only spinning you should be able to drive a flat blade of some kind under the edge and apply pressure as you back it out. If the plug is out and the threads are stripped then any good parts store will have oversize plugs that are self tapping and will screw in with a little effort. KB

William

You could try this fix, haven't used one, but seems like a way to prevent pulling the engine.

Years ago, when I was heavy into Model As, we were helping a club member put his "new, rebuilt" engine in his frame. Went to tighten the drain plug, and found the threaded bung was loose in the pan! Well, only one way to fix that, drop the pan and rebraze the bung.
Boy, that was a fortunate find, as the pan was filthy dirty, even had blasting sand in it. The block looked great--turns out the rebuilder had some kids working for him & I guess they just didn't care what the parts looked like on the insides!AFAIK, that motor is still going, so it was only the pan that was messed up. Whew--dodged one huge bullet there!
Unfortunately, this is only ONE of my stories of finding sand where it shouldn't be, and of "Fix with paint" restoration work done by paid folks!

I have one of the aforementioned plug repairs in my '24 runabout. YOU MUST FOLLOW THE INSTRUCTIONS , as it will have to be clean to epoxy new plug adapter to pan after threading in. Works very well so far,the other repair is to pull all out and cut out old thread ring then weld new in.

yes the plug is still in. as I turn it, it will loosen, then as I keep turning it will tighten a bit,then loosen again etc. etc. etc. I tried to use a puddy knife to apply downward pressure but there is no lip to catch on.

William - Can you possibly grab the plug by the edges with vice-grips and pull downward while turning the plug to unloosen? Seems like once you get a thread to "catch", it should then unscrew outward,....???
