BTTT

 

If its the one up the top, near the turbo,
an old spark plug does the trick. Not a scooby one though as their to small. Just take off the ceramic bit with a hammer
This'l see you ok til you can get a proper blanking plug from TSL, i think they sell them

 

Same thread as the old 18 mm sparking plugs they use in old motor mowers. You could use an old plug to block the hole.
