http://theoldone.com/components/breather/ actually taps in to the back of your block and elimnates the stock pcv system, the only 'real' crank case breather kit that i'm aware of, not some cheap catch can with a 'vacuum' source from the turbo intake.

Re: PCV Setups??
thats decent, but its for b-series and it $170. any cheap alternatives besides the catch can and vacume source????

Re: PCV Setups??
is it really needed? i have mine from the back of the block, into a custom can, with the hose on bottom, with steel wool inside packed, then the top line goes to the intake tube..

Re: PCV Setups??
yes, the PCV valve is what the problem is. it doesn't like boost.

Re: PCV Setups??
i'm only gonna have a filter on my turbo, no piping. any other ideas???

Re: PCV Setups??
if you've ever seen all the ---- that gets in a catch can, you'd have second thoughts about routing it back in to your turo intake. even if you have a true 'baffled' can which cost about 80 bucks just for the can, some of the stuff still gets by and sucked in to your intake, which in turn lowers octane rating and can cause detonation.

Re: PCV Setups??
if you're worried about it, you can set up a pcv system like the ones in the diagram above, but be sure to use a real baffled can, not one of those cheap 15 dollar ebay 'catch cans', or else all you'll be doing is sucking dirty oil and unburnt gas vapors in to your intake, which your engine will not appreciate too much. if you're only gonna have a filter on the turbo, just drill a hole in outside of where the clamp will be on the turbo and shove the hose in there and use a 'slash cut' on the end of the tube that will be inside the intake/turbo inlet. basically, just cut a 45° angle on the end of the hose and have the 'long' side of the cut facing the filter, and the 'short' side of the cut facing the compressor wheel, this helps draw more vacuum the higher the load is on the engine (the air rushing past the 'angled' tube aids in drawing more air out of the tube). so basically, here's how you should set it up, take pcv valve out, replace with a tube going in to one side of the breather can, another tube going out of the breather can going in to turbo intake with a 'slash' cut on the inside of the actual turbo inlet side of the 'tube'.

does a hose just plug into the pcv spot or do i need something to connect it???

and for a catch, All I run is a really small automatic tranny cooler, its got some crazy baffles inside and it fills up with nasty black ----, brown ----, and a clear liquid that I think is water, hahaha, I sure as hell wouldn't want that going into my engine. The real reason for setting up a catch can is because under boost, the PCV closes, and all the nasty gases and oil vapours build up residual pressure in the crank case essentially pushing back onto your piston rings. This will cause added wear on your rings, eventually leading to blow-by. It also robs horsepower because your pistons are now fighting pressure on both ends. The catch can simply acts as a filter, 'catching' if you will all the nasty ----. |

Re: PCV Setups??
is this ---- available at a parts (autozone, nappa), or a hardware store??

Re: PCV Setups??
i think slash cut in the exhaust is easiest. I took some old coolant metal 1/4" pipe i had laying around, slash cut it, drill a hole in my down pipe, put it in the hole, weld it up (jb weld will work too), the metal pipe is long enough where it comes up into the engine bay so i just connect a hose from PCV to slash cut. I don't know how well it works b/c i don't have clear hose hooked up but i'm sure its doing its job.
