Hi . I have the same issue with my oil light coming on when warm perfectly normal from start up , I have checked with a external oil pressure gauge and the pressure drops to low for my liking at tick over but picks up when revved.
I have had the oil pump out and checked , all looks ok and changed the spindle whilst it was out but dont know the tolerances of free play there should be on the two cogs .
I will watch to see if this thread goes any where to helping us !
Cheers Andyoh
