An oil separator is a very good idea. I have installed them on both my Honda Civics and 2018 Ford F-150 and they all do their job. Our 56 Y is an open system so none on it.

Hey everyone. I'm in the middle of an engine build (almost complete car rebuild) of my '70 GTO with 400. I'm going to get the Dual Flow PCV and Motown oil separator myself and will be mounting the PCV to my valley pan. It will be interesting considering my conversion to EFI with a Fi Tech Go EFI 600 but I've always had problems with excess crankcase pressure due mostly to my own ignorance. Your posts have been informative, so thanks for the real life knowledge. I'll let you know how everything works out.

Just follow up.  A few posts up, I mentioned that I suggested to them making a grommet available to purchase with the valve.  I was curious today and took a look at their website.  Now, they do offer a grommet.  They also offer a couple other adapters, including one called a valley pan adapter.  I don't know how well it would work with a Y but it is assuring that they listen to suggestions and are introducing new stuff.  Maybe someone could be the guinea pig for the valley pan adapter   That would be the ideal setup for most Ys, if it does fit well.  And if it doesn't, I have a feeling they would be open to producing one if there is enough interest.

Charlie.  THANKS for the link to the adjustable PCV test results.  I hadn't seen this information before.  Again, thanks for all the information you share with us here.  Appreciated!

Pretty much.  I have no way to verify their claims, but if it does function as advertised, then it should be better.  It does seem to be working, so that is good.

Charlie.  I guess you wouldn't realize any change in your engine's operation unless what you were originally using as a PCV unit was not working appropriately because of the PCV application not complementing the engine modifications (example: camshaft timing) you have introduced.  Sound right?

Regards,
Charlie

Seems good so far.

Charlie.  Any more comments on this adjustable two stage PCV unit after running it for several months?

Thanks.

Charlie.  THANKS for field testing this for us.  With any significant changes to OEM engine operating parameters, it would seem that an adjustable (tune-able) PCV assembly would be an ideal way to appropriately tailor it's operation.

Idle adjustment seems fine.  According to the instructions, excess oil consumption, and unresponsive idle mixture screws are things to look for for excess PCV flow.  Those look good.  Signs of inadequate PCV flow have to do with oil getting out of the crankcase in one way or another.  That seems ok.  I also had to close the throttle butterflys slightly after installing the valve, which means more air was coming through the valve, providing more evidence that flow is adequate.
It does seem to be working better than the generic one I have used in the past.

So first impressions are good.  We'll see how it does over the long term.
