Yes a huge difference. I installed just the provent on Helmut back in '06 with my own hose and fittings which is not as pretty as DR's, plus I mounted the vent in stock location for the air pump which isn't as effective as DR's approach.
There is no oil in my plenums or intake. Zero oil...
No oil in the intake charge makes for a happier engine with less pinging from low octane of the oil...
My car doesn't smoke any more like it used to...![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)
No noticeable increase in performance... We get all that stuff from Ken!!

That will work...the hoses look tight enough so no need for clamps![thumbup](https://rennlist.com/forums/graemlins/thumbup.gif)

Here is my simple less elegant solution:

By using smaller hose and no clamps, small hose stretched over DR's fittings don't need no clamps, I got just enough, for me, clearance to mount the plenum with only a slight tilt, but good contact to PorKens' rings.

The biggest issue with the smaller hose is that it is a smaller hose and will vent less than the design DR came up with. I still have a large bore hose coming from the filler neck and from the T to the Provent is the same. Only needed to source another 2.5' of hose nothing else.

Well then ofcourse there is no more oil in the intake and it has nothing to do with the type of seperator being used here either.

There must be a cheaper and simpler solution. I noticed the one that goes under the oil filler. It was ugly but supposedly works and is only $100. Maybe all it takes is to put some scotch pads in the oil filler.

The main crank vent baffle plates help - but the 928 Intl one is quite simple, the ones made by John Khun (also alternative by Louie Ott) are much more elaborate & effective - but again only for those specific breathers. John's was availabele commercially - not clear if he will make more - Louie's was a personal project.
The Provent is designed to be able to be configured as either an open atmosphere output or a closed system where the output of the provent goes back to the intake. Even in closed mode it does have an overpressure blow off.
