I have no PCV system.....
I vent my crankcase to my catchcan setup to help relieve some pressure in the crankcase since in every type of FI your going to have some blowby.
I like the thread starter hated having oil all over after just having filters on my valve covers...so i did what i posted above. works awsome...
You guys are right though..... mine is a lil spendy....
$104 in 90 degree fittings
$74 catchcan
$20 2 -10an male fittings
8 ft -10an hose.... $$free from a friend.. spool of 30 ft.
$20 2 -10an male fittings to be welded on valve covers or custom valve covers...

how much oil accumulates in the catch can? how often do you drain it? every oil change?

Thanks... So if I cap the rear pass side and run the rear driver side to my can I can remove the entire pcv system and cap the intake???

You can cap everything, remove the PCV, run a line from each valve cover (-10 is good) to a breather/catch can. This is the way mine is, but I went -12.\

Edit: you can see my pic below, it's not routed here, but there will be a line routed from each VC to to it's own breater/catch can, no PCV or anything else.

Thanks man ^^^ I'm going to ditch the pcv tomorrow and vent the driver side rocker cover to my can. Sweet build BTW!

Thanks every one for the help. Sorry for all the newb questions. My first trip to the dyno after the blower The timing cover seal pushed out of the front of the engine. I about had a heart attack. So I just want to make sure i have every thing vented and plumbed right. cleaning 5 quarts of oil out of the engine bay was a nightmare.

I didnt have any pictures of mine seeing i just did it. But i was having the same thing you were having. Pressure was building up and blowing it outta my seals. I tried the breather..and ended up having that still spray oil. This is how i ran my catch-can.

The little piece coming out from what looks like the intake is actually the LS6 valley cover hook up. I have NO PCV hooked up..just straight to the can. All other connections not shown for the PCV are capped off on my car.

Thanks for the pic Thats what I'm going to do tomorrow (-) the line line from the gally cover. mine's still the ls1.
So you had a seal come out too. I about **** a brick... never seen that much oil come out of something so fast in my life. I was standing right next to the car watching the fuel pressure gauge for the tuner and it poped at 5,000 rpms

yes sir, I lost the crank seal 3 times on the dyno, luckily never at the track or it would have been ugly .

Mine was coming outta the rear seal. Blowing oil, hitting the flexplate, which in returned soaked the trans pan..and hit all my exhaust causing a LOVELY smoke show. Seriously looked like the car was on fire. So happy it doesnt do that anymore.

Sorry to hear, as pissed as i was. I was thinking about how bad it would have been to have the rear go and soak my $700 clutch set up that only had 300 miles on it.

Good thing is..it didnt push the seal..so after running my catch-can...i havnt had a problem with oil blowing out.

conan

Good to hear. After the seal i put the breather on the rocker cover and haven't had any issues other than the oil leaking on my nice clean engine bay. Which lead me to this thread.

Thanks every one for all the pics and info. Today after work i got the car in the shop and the pcv system is no more. Caped the the intake and the rear pass side hole, and ran a new hose from the driver side rocker cover to the can. Works great so far.
