I'm building a tubo blacktop.

Ive got to the point of sorting the oil lines. I want to plumb into the oil gallery from the torx headed blanking plug (2-3 inches left of the oil pressure switch.

I dont want to t off from the pressure switch, want to use the RS position.

Does anyone know what thread it is, I want to order up all the bits.

 

Here is a better picture, (ive circled the port I mean)

 

I hope youve got a strong torx bit i tried to get the one out of my block and ended up snapping two bits clean off and it didnt even budge
