Pros & Cons-- Catchcan setups vs Breather setups & Proper Ventilation

I have been reading over PCV threads ever since I joined this site. It seems it can be done with research and careful attention to what is going where.
Automagicls1 posted something neat the other day, and also I have read where other people have opted to do this, but I am curious if there are drawbacks to running two passenger side valvecovers and running a breather with a checkvalve in it (Rx makes these)
Also it was suggested that it would be even better to weld in two -10an fittings and just run the lines to a puke tank.
Just wondering if this would have any long term effects on motor I want to take care of any way I can.

I would run a punk tank with as big of line as you can put on it. Probably -12an. I use 1.25" hoses on my motor. There is no issues with venting the crankcase, short or long term.

well you already know my opinion.....btw heres 450-500 miles on the corn with a #10 off each cover to my puke tank. no way in hell i'd run one of those PCV setups. scary because a couple years ago I never really had a good crankcase ventilation setup and to know how much moisture was in my crankcase then. I never get any oil in my tank though which is a good thing!

so to clear it up a little..
So with an LS1 Valle cover..
Run -10an/-12an off each valve cover to a vented catch can for each cover correct? no PCV valve? no breathers on the valve covers?
valve cvr catch can

no vent line to the turbo/SC intlet, nothing right?
seems to simple to be true... lol

people have been overcomplicating things for a long time man. The proof is in the pudding.

I'm doing this same setup as post 4 and 5 on the first page.......plus i might do a small electric vacuum pump that always runs and pulls vacuum very mildly full-time, mostly for when the engine is idling or when I'm cruising steady for a long time. I think I'll connect that to the valley cover port. If I see any oil at all in the vacuum pump or in the outlet hose, I'll ditch that and just keep the catch can......When I hit it hard, any back pressure will push its way out to the catch can but at low or steady rpms the vacuum will pull crankcase gases.

Some have said that is more than enough. I believe it will be but cannot attest to it personally. You may be the guinea pig on that one bud.
The real question now is, where I should weld the #10 fittings on the valve covers that will allow the coil packs to sit without compromise. I dont have them in front of me right now, and wont any time soon.

just reloacate the coils. or come off the side of the cover.
anyone used these? Seems like theyd be pretty easy to come right off the side with a -10 bung.

When I get my heads here at the shop and get our fab guy to weld on the bungs I'll show you guys simple and easy what needs to be done, but that said there have already been posts and pictures that illustrate that in here.
Might even get David(MM) to make me a custom breather that is larger than the ones he currently makes. I'm mainly doing mine for safety in case the crank case becomes pressurized it will end up in the puke tank and not all over my tires at 130mph in the 1/8th. I'll be putting mine somewhere away from the tires that is for sure.
