Interesting reading this. I have a TR7 which desperately needs an oil change but whose sump plug is stuck fast (18 previous owners hans't helped things I guess)
One of the ideas suggested to me (other than drop the sump & sort the plug out) was to remove the oil filter, put a big bowl under the filter housing and start the engine.....this leading to all the oil being pumped up from the sump and out into the outside world. Obviously one would need to stand over the engine ready to pull the coil lead out once the oil was drained.
Filter is vertically aligned and is a spin-on one, so can refill that with fresh oil before starting.
thoughts, comments ???!
cheers,

Sounds a bit risky to me, I would remove the sump and put a new plug in.

Stu,
Why not use a vacuum pump to remove most of the oil (there's a thread running on them in parallel with this one) to remove as much as oil as possible before taking the filter off?
You can get quite cheap versions for boating suppliers that include a 5 litre can to collect the waste oil as you suck it out.
Should leave you with less mess to clean up, at least, after you've sorted the sump plug.

But surely if the oil is being pumped out through the missing filter, it isn't circulating round the engine? The filter is the first stage after the oil pump, not on the oils's return trip!
That sounds extremely silly. How long will it be running with no oil before the sump is emptied?
If it were me, I couldn't bear to live with it and not sort the plug out properly. Weld a bit of bar onto the stump?

Don't do it you'll have no gallery oil pressure at all.
If you have a spin on oil filter thats a conversion and use CVH Ford ones.
Get it to a garage who can put it on a ramp and dril/chisel the old one out & get a new one from Robsport to replace it.

Now who dream`t that one up,
>>this leading to all the oil being pumped up from the sump and out into the outside world.
into the outside world is correct,unlikely it will be directed
in direction you wish
I don`t understand the reason for wanting all oil to be removed?,you cannot,a certain small amount remains??

Stuck sump plug
I presume the corners of the plug have been rounded off as well. Machine Mart sell a set of Irwin bolt grips. This is a set of different size sockets but instead of the internal flutes being vertical they are reverse spiralled. Extremely effective in gripping a damaged bolt head. Invented by Snap-on whose own full set costs a couple of hundred pounds but Machine Mart sells a few of the most usual sizes for £23.44. There is also an add on set for about £19. Obviously they wont last as long as the Snap-on but very effective for the occasional job.

Nothing to beat a Stilson wrench! I've got a couple of these in my toolkit and when all else has failed they seldom let me down.

Formula1 used one of these sockets to remove a locking wheelnut that wouln't respond to the adaptor(they'd fitted it in the first place which is why I went back to them).Very effective and with the nut sunk into the wheel nothing else could get near.

These sockets cut into all the flats whilst a stilson can only grip two. And as, Formula1 points out, a stilson cannot deal with a bolt head that is recessed. So clearly a stilson can be beat.

I didn't try it in the end (and I have no idea if the oil filter is on the return trip of the oil or not!).
I painstakingly filed the sump plug back to a square then a smaller square so a brake adjust spanner would fit on it. Then it came undone, and fairly easily as well.
So no crazy antics with removing the filter and starting the engine required!!!
