Can you get a fine screwdriver behind the head and apply a little pressure while you try to undo?

Others on here have experienced such problems and will no doubt soon advise.

I must say that when a nut is stuck in such a way I would be tempted to think of drilling it out very very carefully........heat of drill.......oil...........fire!!  But then after doing so you could remove and refit a new plug. ;)

Others as I have said will no doubt give further / better advice!!

Doz, haven't got a screwdriver on me and my house is a bit far from where I am and am parked somewhere I can't leave my car unattended. Although doesn't look like I will be able to. Nut hasn't come loose at all

In that case I would not do any more as you will probably need a new plug, and I suspect the sump threads are damaged, which will / may require a special fitting that others can advise on. ;)

If it's not leaking then best left alone until you can get it some where more suitable.

Ironically this is the best place to work on the car. What I need is a minion but he has gone out for a couple of hours. But yes, I will leave it as its not leaking.

Its likely, if the sump plug is turning (ie, you haven't just chewed the torx), that the sump is stripped. You may be lucky, and find its only the plug.

Sump not too bad to change. While its off, clean up the strainer.

If its only the plug, will the sump still need to come out? Would doz' method remove the nut if the sump is stripped?

Is there a guide to replace the sump?

My method will probably get the plug out BUT if the sump threads are knackered then the sump will need to come off at some point.

You will need a Heli-coil kit by the looks of it. Be careful if you drive it, keep the revs low & watch your oil pressure. You will more than likely need a new sump plug too.
p.s. Welcome back Lizzie  :y

How odd... is this just the torx one?

These are a very low torque... 10nm. I seem to remember some months ago yours torqued up fine, with no signs of stripped thread etc... you haven't had any kwik-fit style oil changrs near the car have you?

The good news is, the lower sump pan is a peice of cake to change :y

Just put a new sump on it. There's not enough material in the sump to hold a thread insert ........ my own opinion despite others saying otherwise  ::). The sump plug is originally screwed into an ally insert that's swaged into the sump.

James, no one has touched the sump plug since your kind self, but if I'm honest it felt a bit tight. Maybe your torque wrench needs calibrating  ;D 

So its possible that the nut is damaged (easy option) but if its the sump, it would need replacing or helicoiling.

Is there a way of finding out which is it (or would that be doz' method). Either way I will probably need a new plug at least before I start.

Agemo, didnt think it would be a problem to drive, but not so sure now.  :-\

Yup, for v6 sump, I agree, replace lower sump
