!PCV???? worth it?

Plug every hole, and run a breather, just stay on top of your oil changes.
This may sound dumb but it works, I'm using a Detroit Diesel fuel water separator as a catch can on my Z-28. It came with the mounting bracket, the filter and has a petcock valve to drain the oil out when full. I ran both lines into a T fitting then through the inner fender and up to the filter, which is all hidden so there is no clutter.
Then the outlet line runs next to the radiator and up to the throttle body. I was getting lot's of oil consumption and water condensation back into the intake but after running this set-up the intake is nice and dry. I painted the bracket and filter assembly a nice anodized blue so it looks aftermarket and hides the Detroit lettering.

I would say that it would be minimal. I ran breathers on all my old motors with no problem. The only one that omitted any oil was the one that had 150,000 miles on it. And it was still very little. As long as you clean the breather after each oil change there should not be a problem.

Here's a pic of my set up with braided lines:
As you can see, you still need to maintain the hose from the throttle body to the passenger side valve cover. That will provide the fresh air.

As for coating the engine bay in oil mist. I have been running a breather for about 4,000 miles and it only smoked a little bit for the first 1,000 after the breather got a good coating of oil on the inside it stopped. Honestly the PCV delete was one of my favorite mods, the car ran so much better without it, something about having only air fuel and spark in the combustion chamber just makes it run better

hey guys as an update here is what I did...
just capped off ANY fitting I saw....all of the ones on the TB, valve covers, etc
Then I added a Metco breather where the oil fill cap goes as ventilation...we will see how it goes

You COULD run a 3/8" hose from valve cover to valve cover in the back but you don't have to, the engine will equalize pressure internally. Cap off everything else. Sticking breathers into the hose will look really messy and cheap IMO. it will work fine, but won't look great.

I also drilled my oil cap and stuck a breather on top of that. Its a PITA with a strut tower bar, since the bar practically goes right over the oil cap, but I made it work by using a tapered breather filter

Cap off the PCV port on the throttle body and remove the PCV hose, it will no longer be needed.
