Does anyone know if the 90 degree fitting is removed from the intake valve cover. Is it threaded or smooth bore? If threaded what size? If smooth, then hole size?

When I did my valve cover gasket job on my 01 a few months ago, the PVC on the intake side was smooth. I had to replace it because I had broke it lol.
