How important is it to restore the sump capacity if Im only chopping 30mm or so off the deep part of the sump.
I'm considering not bothering with the extension bit of the mod. 
Any thought on the matter would be appreciated. 
ps when I get someone to show me how to do it I'll post some pics but nothing exciting yet. (how many chassis does anyone need to see!)

HI Adrian,
The volume of oil in the sump pan is determined by how much oil is circulating round the engine as max revs. If you reduce the volume of oil by not doing the extension then the engine will suffer oil starvation at high revs followed rapidly by failure!
Do not be tempted just to raise the oil level above the max mark on the dipstick - it's there for a reason - The crank and rods will dip into the oil when the level is raised causing major problems, loss of power and even crank failure.
The extension is not hard to do compared to some of the other tasks on the haynes roadster, its not a short cut as you'll be doing it later when you fit a replacement engine!!!
