Thread pitch of valve cover oil drain fitting?

[nextelbuddy]

So with my current project I need to replace the PCV oil drain line that goes from the valve cover down to the oil pan.. I have to convert to a stainless steel line with AN fittings to clear my turbo manifold.

I understand in my S54 which is an older S54 2002.... I have a rubber line coming off the barbed fitting and that barb fitting is 1/8npt So I know that fitting spec

But for the top one that's a banjo bolt

Does anybody know what the thread pitch of that one is?

I need to get a fitting that goes from whatever thread pitch that is to a -4an.

Maybes someone has a loose one and can mic it.

Normally, RealOEM gives you fasteners' specs, but because it's a banjo/hollow bolt, they don't I guess. From memory, I'll guess m14x2mm (coarse) fine would be 1.5mm, but it looks coarse to me:

Thanks man. It appears to be M12 x 1.75" thread pitch.

Sounds right
