I have searching through the forum and the net about the oil catch cans and what the differences between them are.
I am considering the Provent 200.
A couple of things I am uncertain of, are:

1. The existing hose from the rocker cover looks like it is about 5/8" internal Diameter. Is the Provent inlet and outlet the same size?. Cant seem to find any specific info on what size the inlet & outlet are on the unit.

2. I was also looking at a previous post I found on this site, (a pdf file) and it mentioned that the restrictor was removed from the original hose and refitted to the new hose. Is this restrictor in all models or only some.

Thanks
