ATTN: everyone who has a fliter on the valve cover breather
PLUG IT INTO THE INTAKE! I know many people here have said this before, but trust me, IT IMPROVES YOUR IDLE AND LEAN IDLEING/VAC LEAKS. It was an amazing difference when I acually connected it. So do it! now!

The breather was only added to cars for emissions reasons. The only thing its gonna do is pull some vac at idle. I'd much rather tune my idle with ms and have my breather vented to atmo with a catchcan though. Under boost thats the only way you are gonna remove crank case pressure quick enough. I'f you live in an area that has emissions checks though....thats not an option for you (once a year that is :P)

I'm not a fan of the PCV systems anymore to be honest. They were primarily an emissions thing.
I run a turbo honda with just a vented catchcan... no issues. This is along with many others I know with turbo cars.
I know people will argue with me over that, with regards to getting some vac during cruising and with the proper pcv, nothing during boost. But honestly.. that system then blocks venting during boost... which i do NOT like at all.
My ideal setup would be a catchcan and an old gmc electric vacuum pump pulling vacuum from the motor at all times. I just haven't found a good deal at the junkyards for one yet.

To avoid the leavy PCV issue and yet still have some negative pressure on the crankcase, I wonder what the effect would be of plugging the PCV ports and simply connecting the left side port to the intake between filter and compressor inlet? Granted, assuming the air filter is in reasonably decent condition it won't pull much vacuum, but it should at least be better than the little vent filter I've got on there now...
Note to self - buy a fitting and re-connect that line.

I have both lines routed to a breather right now. It needs a catchcan though as the spot it's routed to stays oily. I personally don't want oil going into my intake manifold, or exhaust gases for that matter.
Joe, if you do that, just don't put it too close to the filter, or the oil will probably get on the filter anyway.

Why would it really matter if the breather is connected between the filter and the turbo? Its just a source of fresh air for the crank case isnt it? As long as its clean, it should be fine.
As for the PCV. I am guessing some of you recommend a catch can because the additional boost causes more oil to be pushed out of the PCV during vacuum conditions?

i am really trying to read all this and take it all in and learn from it, but i have to admit, i am more confeused now...
it is my understanding that the breather side of the PCV system is just a source of fresh air that is supposed to circulate through the crank case and help absorb the vaporous gases and move them along towards the intake manifold/vacuum source to relieve the crank case pressure caused by these gases
so why does it matter where the fresh air is coming from?
as long as the PCV valve is functioning properly, you should not have any problems, right?
if i am understanding this wrong, someone please point it out to me, i will not get offended!
thanks
