I'd probably put a check valve on the wiper line anyway. You absolutely do not want ethanol fumes to find their way to the vacuum wipers. Nor to brakes for that matter. Check valves help to keep condensing vapors from destroying things that are less than compatable with today's fuels.

Any insight on connecting the vacuum end of the pcv onto the same vacuum line feeding my vacuum wiper setup?

IAN, YES.

I'm not going to change mine as it looks original and the car doesn't do many miles each year, so if I have to change oil a little more often it is no bid deal for me. I still want to ask the question to you guys that have done the conversion, did you notice a definite change in the cleanliness of your oil?

Although expensive, that Wagner adjustable PCV valve is an interesting solution. I expect that they don't sell enough to allow for huge profits. I think that it is a clever idea and would not blame a person for investing in one. The performance-enhanced daily driver might actually benefit from using this. It would allow one to actually control the flow and mitigate unintended vacuum loss due to an unfortunate PCV choice for a given engine carb and cam arrangement. If you did go this route, you might want to also get a rebuild kit while it's available.

And, yes, a properly-engineered PCV valve will keep the crankcase and oil cleaner. Even more effectively than a road draft tube. A poorly-engineered PCV valve choice will possibly cause either poor crankcase scavenging, or, excessive vacuum loss that can lead to idle and/or off-idle issues.

I only thought they were for emissions. I don't have problems with fuel smell. How does it achieve a cleaner crankcase?

It would be interesting to find out if that expensive valve is of any benefit. How would you quantify that in order to test it against other off-the-shelf valves? How do you know that you have the "right" pcv valve?

Have you ever noticed that gas fume smell in your garage when the car has been sitting enclosed for any length of time?Thats from the open crankcase having the Road Draft Tube.Install a PCV and close off the opening where the Draft Tube was(or still is for appearance only blocked off) and that smell is gone.Just one of several reasons for installing one.

  

Here are some good reasons;
• Properly ventilates crankcase, resulting in cleaner oil and cleaner engine internals
• Reduces emissions
• Reduces moisture and acidic vapors in your engine’s crankcase

i don't know maybe its techy, adjustable its bright and shiny.....

now tell me something why do some PCV valves have two hose barbs?
