I've read that you do pick up a couple hp that way but who knows.:scratchchin If PLstang doesn't post here, I'd PM him.
Thanks, I was thinking the same thing.

Man that's a good question. I wondered the samething before I put a catch can on mine and decided to keep the PCV system. I was worried that venting those oil fumes into the air instead of the intake would have 2 potentially negative side affects....I might affect the tune and a dirtier/hotter engine bay.

I would think it would totally be different on a boosted application since vacuum and pressure are critical. It's really hard to say if it would be beneficial on a N/A application. It's a pretty complicated process(PCV system). I wouldn't change it without consulting a Ford engineer or equivalent knowledgeable tuner.

What is the benefit? Where all do you put/use them?

It is suppose to aid in crankcase blowby. It should help with a bit of HP also. I am not sure it would help at all with a N/A car. I will maybe try it and see if it helps at all. I hope Plstang will chime in.

I've gone back to the PCV system that came with my Vortech. Honestly saw no real benefit from the breeathers. And I got oil all over the place.

Thanks again, I was on my way to Autozone. I just saved a good amount of money thanks to you.

LOL can't say it wasn't breathing I guess. More like blowing it's nose with a wet tissue. That's exactly why I didn't go that route.
And on another note, it was also sucking all that hot engine bay air into the crankcase. I'm sure that didn't help with operating temperatures.

Yep instead of the PCV tube that pulls cold air from the CAI. I can see the hotter air from the PCV delete would negate any added vacuum picked up in the crankcase. Makes perfect sense.

Just keep the pcv system intact and you'll be fine.

On my Ducati motors I use one of these crankcase breathers (which is more of an adaptor because it's hollow):
58cycle Parts & Accessories Webstore
From this we run a 25mm hose up to an underseat "catch tnak" that increses crankase volume. Them a hose runs from that too the airbox and it is capped with a carbon fiber reed valve that closes after each engine pulse and in a sense created a vacume. Pic attached. This setup is goof for 5-7hp on a 135hp bike. It promotes better ring seal, prevets ring flutter and evacuates the crankcase so the pistons have a lot less resistace to fight during their downstroke. They even work better on FI cars because the push the rings into the cylinder walls. It also solves a lot of potetial leaks because of the low pressure in the crankcase.

I plan on modding my valve covers to accept breather hoses and I will run them to a catch tak like a Morosso or Canton.
