So my original idea didn't hold up, Has anyone taped into the valve cover ? I was looking online on Russell performance, the smallest NTP to AN is 1/4. and the hole looks like a 1/8

Will taping a 1/4 NTP work for this ? or is there not enough material for it to hold up.

also This looks like a -8AN for the catch can, can anyone confirm the size.

Thanks

 

STM has -6AN valve cover fittings that you can push in.

 

I did call them this morning spoke to Brian, they don't have the -8AN which I believe is the size I need.
