180ml, the same as a normal service.
Thanks for the info your suggestion is the fix for sure its the female thread in the casting thats gone and the plug just spins ive used time serts before on exhaust manifold to good success, although the male plug is just spinning neither in or out, I thought about welding a long bolt to it so i can apply outward pressure as i turn hopefully picking up some usable thread with the pulling force, then like you say put a time sert in Gently drive an EZ-out in the plug and back it out. Then replace the plug.
If the threads are tits-up a Time-Sert or Helicoil is your friend. There is a thread on the big adventure site that discusses this.
Trouble is their is no undercut flat to the plug to pry under its more like a grub screw thats seated down beyond the surface of the casing hence having the idea of tack welding to the plug im in no rush to do the fix as the oil in your their feels ok and i can still change it via drainage from the speedo sensor hole, i will have a go sometime when i got the time to set aside and a good clean tidy workshop thanks for the inputHey, I have done a good amount of sump plug helicoils in my time, but only on cars. Normally I have found that in this situation there is 1 or 2 threads of the sump plug through into the casing that are not dammed. The good threads struggle to engage and drive the sump plug out, so I normally get a flat head screw driver in between the head of the plug and the copper washer ( not to damage the sealing face of the casing) the gently leaver it out at the same time turning the sump plug. This it to try and force the undamaged threads to engage on something. Then repair with heli-coil or timesert. And ofcourse fit a new plug.
Hope this helps.
