R50/53 mullicated oil drain plug
#26
So, I tried every method to get it out but couldn't. I ended up using a grinding bit to grind it flat so I'd have a surface to drill in and then use a left hand bit or an extractor (I have both).
Unfortunately, I can spend 5 minutes drilling and not even scratch the surface. Is there a special drill bit that I need? I can't drill at this thing in this position for hours. Something isn't right.

Do you have a Dremel? If so, you could use parting wheel & make 2 grooves 90 deg cross. Then use a hand (hammer) impact tool with large phillips bit to get it to turn,.
Or just bite the bullet & pull the oil pan so you can work on it on bench.

I will probably just end up pulling the pan if needed.

I started drilling before the slot suggestion, there really was no room left when I looked at it.
I doubt anything could have moved this. In the end, I couldn't turn it with a number 6 easy out, and a breaker bar.
Thanks for all the help.

Actually, I’d suggest a used oil pan. There are several on eBay at the moment in the neighborhood of $80 w/free shipping.
And don’t forget to grab an Fumoto valve (p/n F106 below) for when you swap it out.
========
ETA: Maybe before you give up on this pan, you could drill a hole in the plug to drain the engine oil, then remove the pan and try to drill out the plug on a drill press with a proper sized bit? Might save you the cost of purchasing a replacement.

Was thinking of getting an extractor that could work for both power bleeding my new slave cylinder and either doing oil changes with it moving forward or at least getting the oil out for this time.
I don't have a drill press and have never used one. If am getting a new pan I might drill a hole through the pan since that takea far less time than that plug in that position. Of course the pan would be trash but it's probably getting close to being trash at the moment lol.

1. Did you see my post from YEARS ago and repeated regularly: the bung is a 1/2 inch perfect fit ..... the metric is loose and screws you up
2. These have never failed me on a stuck bung
these are IRWIN brand, I'm sure there are others. They bite into heads under reverse (remove) motion .... hammer it on to get a grip then the more you torque the deeper they dig
3. The bung for a GEN1 MINI is a one time use, throw it away item ...... most folks miss that point. Then the problem becomes the deterioration of the plastic seal .....
got my first MINI in fall of 2002 .... been turning wrenches and offering my garage and tools ever since ...... if you want to listen to me tell sea stories while I help you DIY and learn!

I have the extractors that you pictured but there was really nothing left of the bolt. The pictures of what appear to be left do it no justice.
I have been turning wrenches since the late 90's myself and this was an exceptional mess.
Spilt milk at this point unfortunately.

While on topic, anything else that I should be doing while down there? Huge fan of not broken don't fix it, but curious. Also, any suggestions on getting the oil out of the old pan? Drill a hole? Would rather not buy an extractor.

I'll tell you this, I have removed several of these "frozen" oil plugs, but I found all of them the flat gasket area was the thing that was freezing them, from coming out. I will admit that yours is butchered more than any I have tried to remove, but maybe if you use a dremel tool to grind away the flat part of the plug, it may just come out easy. I have never had to change a pan, in the dozen or so, I have done with Minis'. Hope you have success!
