That for the moment doesnt leak oil (shhhhhh don't tell it).

it's alive, ALIVE I TEL YOU. MUHAHAHAHAhahahahahahahahaha :evil::twisted:

[ND4SPDR]

It's obviously one of those electric superchargers that EVERYBODY knows adds, like, 50 horsepower. ;-)

Looking good, dude. :)

[jao]

hmm whats that?



catch can made of ABS plastic?

sho nuff. lowes, about $12 invested including the fittings on the ends. stuffed it with steel wool, its workin great.

That sounds like a good idea.
I love going to lowes and buying stuff for my car.

Cheap stuff eh? Home Depot Performance parts are better :roll:

That line in front a vacuum line? I assum eit is... you may want to pack the can with something with the brand name "Steel Wool 2". Its a plastic coated fiber, so its all bound together, so none of it will get sucked into the motor. Steel wool seems dangerously loose to be subjected to even a little bit of airflow

[Jeph430]

So what's the purpose of those, and how do they work??

catch most if not all of the oil coming out of the crank case breather on the side of the motor, while providing positive crank case ventilation, which aids in ring sealing and reduced pumping loses. it also helps the oil seals seal better and keeps your car from smelling like an old MG in the passenger cabin. its good stuff.



poi: I'm not terribly worried about the steel wool departing the canister, it'd have quite a trip before it even made it to the compressor inlet, and then it'd hafta get through the intercooler.... and mine's bigger :-p

[Sp3aK]

I think my dad and I take the cake on Home Depot perforamnce. We made intercooler piping out of PVC(which is holding up suprisingly well.. heh), as well as an oil manifold, which also seems to be doing its job(shh).

This is probably retarded, but what about when under boost? Surely there's a checkvalve to avoid pressurizing the catch can, but is there any way to vent crankcase pressure when boosting?

[stylngle2003]

i think he retains the check valve in his current setup, just made the hose go to the can before it gets to the intake

[Geoff240Ti]

I've always been confused by the catch can way... I must be missing something.

On a standard 700 series turbo the PCV box under the intake is connected to the pre-turbo intake hose.. correct?

So in this case.. is the PCV box connected to the catch can.. then a vaccum line runs to the intake.. or pre-turbo.. or? (this is where I am getting lost) I don't see where it would give as much vacuum to aid in pulling out crankcase pressure. Can someone straighten me out?

Crankcase pressure scares me.. it's what started my old B21ft from using tons of oil (connected a vacuum line from the intake to the pcv.. no check valve, so I'm quite sure I was pushing boost into the crankcase system.. opps!) Needless to say the new motor will have no vacuum line to the intake.. just to the pre-turbo hose.

I'm guessing the vac line runs to the intake manifold with a one way/delay valve. You can run a hose to the exhaust, downstream of the cat, to pull oil fumes out of the catch can. You can also run a vacuum pump, as I plan to try.

Here's a good discussion on valve stem seals and then crankcase venting:

:cough: the hose goes pre turbo, so no need for a check valve

[jpbturbo]

My hose goes to the open air just underneath the brake line junction block.
I stuck my finger in the hose the other day and it was completely dry.
I think that's a good thing.
Now that I'm thinking about it I'll probably build a Mr. cool guy home depot catch can.

[240Psycho]

my pcv is all kinds of dead, auto zone pieces duct taped together that have lost there adhesive. I used to have it connected to the intake pipe pre turbo and it started to suck oil up like a straw and burn it. i think i lost a quart in 3 minutes.

But yea, glad to see the beast is back from its slumber

[oldschoolvolvo]

Maybe I'm mistaken, but I've also seen some cars that just have a small breather filter instead of a catch can. Is this a better/worse idea than what you guys are doing?

It does not allow vacuum or positive pressure in the crankcase...

PCV systems are intended to create vacuum in the crankcase for the reasons Kenny listed. I think when people use a breather, their PCV system started malfunctioning so they just disconnected and put a breather filter in its place, put it on 'cause it looks cool, or have a custom setup for which they didn't think it was necessary to create a PCV system for.

Right?

It's the same idea as Josh's system where the PCV hose plumbs into the atmosphere (no where).

you're probably low on oil/gasoline in your crankcase ;-)
