soo i plan on running a turbo soon but when i do what do i need to do with my PCV system.....can i just stick a breather on the valve cover and run it like that for a while????
pcv system

Sure, it doesnt really become a problem until you start throwing some serious pressure into it so, it will be fine like that for a while.
whats some serious pressure??? i plan on pusing around 15psi on a T3 .42/48
You'll need to install a good catch can off the valve cover.
I would say anything over 350whp I would look for a good breather system.
Come on chaos, I know you have seen the thread about this on turbod16 
Run a vented system: catch can connected to valve cover and a gutted pcv valve.
do not run a breather, it will soak with oil from blow by and eventually make a mess in your engine bay.
Or setup a vaccumed system if you are able to

yea ive seen threads but ive seen so many ways to set up a pcv system.....i just want it to be simple lol
i hate that you just suggested that. I am NOT going to get into full detail of the PCV system. i have spent far far to long correcting other ppls suggestions on the pcv system.
if you run boost with teh stock pcv system YOU WILL PRESSURIZE YOUR CRANKCASE. pressurizing your crankcase will result in blowing your rings. TRUST ME.
you can rip out the stock pcv valve, cap off the IM nipple. and run a simple vented system, or you can get creative and run a vacuum system which IS BETTER THAN A VENTED SYSTEm.
if you really want all the details i'll find and copy and paste my other posts

I don't know, I have seen these posts before and all the explainations but what I do know is, I have been running like this for 4 years and still going. I do compression checks every 6 months and the last was 215 across the board from 218 before I started boosting.
I'm not going to sit here and argue who's right or wrong in theory you are correct but through my experience, the filter is working just fine for me at the moment.

i too speak from first hand experience. i've been boosted and self tuned for 3 years now.
here's the easiest way to think about it. The pcv valve that's in the black box on the back of the block is inplace to prevent any positve pressure form the IM getting into the crankcase. however, if you just run the stock valve in a line *thinking* that it means it is vented, what is actually going on is the valve has a cracking pressure. a very small cracking pressure like .3psi but that is still .3psi that has to build in your crankcase before that valve will let it out.
i'm not here to argue either, i just want people to have the right information.
easiest setup is to pull the pcv line from the im, cap the nipple on the im, and yank out the pcv valve. bam. there is a "vented setup".
add in a catch can, maybe a drain back feature, and some creative ways to add vacuum sources and now you're talking a real crankcase ventilation system.
i'm happy to help where needed

sooo hmm....on the intake mani i just cover the nipple to the pcv? and then i just yank out the pcv valve? so is the pcv valve in the black box ?? not so sure on this as pics would help.....just try not to make it to confusing.....
thanks guys!
thanks guys!
in most d's it is in the black box. some older d's it's in the intake mani itself. google search for a picture of a pcv valve.
and yes, that technically makes a "vented system". you can add improvements to it but that would be a minimum setup.

Ok now I am interested.
I am going to be going back to the dyno after my current completion of upgrades to get more tuning in cause it was cut short last time because of a wastegate issue. What would you consider the ideal set-up? I think I would like to try it and see if there is any improvement in power. From alot of what I have read there should be an improvement in power cause of the oil contaminating the air/fuel mix in the combustion chamber.
From the lot of breather systems or catch can that I have seen Endyn's seems to be the most complete. Do you suggest that one or something other?
here is my ideal setup. it has a vacuum source at all times, and has check valves to prevent reverse flow. the line to the IM is double filtered. the vacuum sources work at opposite ends of the spectrum:
IM provides vacuum while cruising under light load. closes under pressure
Exhaust slashcut provide vacuum at high rpm and high load. closes under low load to prevent the minimal potential for pos pressure to go up the line
-Luke
OK doesn't look all the difficult and some that can be done rather quickly. I would leave the stock box on the back being my PCV Valve is in the intake manifold. The line going from the valve cover to the T is stock vent location? Catch can your standard run of the mill catch can? 5/8 inch lines? Where would one go about picking up check valves that large? I would guess they would have to be metal being one going near exhaust.
Ordering parts tomorrow.
Thanks !
Thanks !
