I know that the AWS pipe can be vented to air but I would like to replumb it back into my Greddy elbow. Plus I just remember what MaxCooper wrote about it seemingly avoiding stales when he had it plumbed back in plus with it unplugged I didn't want oil spraying all over the place.

I no longer have my stock elbow but I was wondering if anyone had an idea of the inner diameter (ID) and outer diameter (OD) of that nipple?

Thanks.

 

18mm OD and 14mm ID, OK

 

Block it off!

 

Thanks for the size!
