i got that size from a previous thead via search (sump nut size) if that helps

Take it out. With an adjustable spanner close it around the thread and then measure the gap between the jaws of the spanner (its a poor mans vernier caliper). All scoob threads are metric. Anything over 4mm is 1.5 pitch.

I've got a micrometer so can measure it fine, just wondered if anyone knew without me having to remove it and faff about ( changed the oil not long ago so dont really want to do it again yet ).

Suppose I could just buy another sump nut and measure that.
