Catchcan has worked real well for me. Need to invest in a good one though if you go that route. The cheap ones won't do much for you.
Friend of mine swapped over to a breather and had a number of problems.

Catchcan worked a while for me. Then recently I took my LS6 intake off for a FAST 90 and oil just poured out. Somehow it was getting in past the catchcan. Still haven't figured that one out yet but anyway, I just bought 2 metco breathers and will no longer have to worry about it.

I think it is time that someone does write up, on removing the PVC system, and putting a catch can in, and any other ways that keep oil out of the intake. I think that this would be the best and then stickey it. Because i would love to know how to delete the PVC system run breathers and be done with it.

I have never gotten oil all over the engine compartment with my breather setup, and my oil doesn't look any different than it did before, I change it every 3k miles anyway so what difference does it make.
The ONLY drawback I can think of is it smells like oil at idle or just cruising after going WOT sometimes.

i had this setup on my old motor and got what you had
buddy has same setup on his and same thing
now i have the breather setup on my mustang and with a 170k miles on the car it does get oil places but that motor is tired
if motor in good shape you shouldnt have any oil in the bay

No, 3k is what the oil industry wants you to mistakenly believe. But if you read up on oil, you'll see that if you look past the propaganda, the 3k is wrong. Check out bobistheoilguy.com so you can see what I'm talking about. The oil is good for much longer as long as the filter is in good shape. Unless your motor has something wrong with it making it wear fast and put excessive shavings into the oil. Why is your new motor wearing so fast? I'm concerned about that.

if you go by the monitors in some of vehicles the determine the oil change. it depends on alot of things. if you do mostly highway driving then oil changes arent as needed as often but if you do all but stop and go driving i would change it early
but the result here is that breathers wont damage the motor. and your not getting anything extra into the oil as you would other wise

I drive my car like I stole it every day, I beat the everliving **** out of it. I would change the oil every 3k regardless of whether I had a breather, a catch can or the stock PCV system.
I'm sure I could probably run my oil for 8-9k miles (with or without pcv) but to me a 40$ oil change is alot cheaper than a new motor.
