PCV and crankcase breather JRSC bypass...

[sjoback]

that's the real way to do it anyway zip!

screw the environment! hehe.

nice breather tank, where did you get it?
can you show us the install on the breather
tank?
btw, is that the t.o.o. install?

[sjoback]

I think that's the summit catch can.

The catch can setup is definately a good idea. Endyn suggests using the moroso can which runs around $80 shipped.

I have it on mine:

What's the problem (other than legal) with just using a filter on the valve cover?

I haven't noticed any oil dripping out of it.

Well, you wouldn't be evacuating the crankcase very well since the SC creates a lot of suction under boost.

Otherwise, you are just letting it vent, not evacuating it.

I don't exactly know the level of importance of the crankcase evacuation, but I have heard that it is a good thing.

If you were doing it race style, you would use a pump to suck out the crankcase vapor into the atmosphere.

Holden I did have a K&N valve cover breather since day 1 of my car purchase. Look at the manifold, its drenched with oil. This oil comes from the PCV (positive crankcase ventilation), I had a stock motor until last weekend. Therefore, the SC would pull even more PCV oil during boost leading to detonation. I chose to completely reroute the PCV and valve cover breather all together to the catchcan.

As for the catch can's purpose - what does it do that the stock pcv charcoal canister doesn't? I thought the charcoal canister located to the right and down of the battery, was there to accomplish this same problem, catching the oil from the crank vapor.

Mine's a '00 GSR and I think it's the same like this from the '96 and newer ones as well. Is this a problem for owners of integras that don't have the charcoal canister or am I missing the purpose of this charcoal canister?

AllMotor your talking about a totally different emission system. The charcoal canister is for the evaporative gasses from your fuel tank, i.e. gas fumes. The purge control unit is not the same as the positive crankcase ventilation, which is for oil.

Zip - you're right, but the pcv solenoid that is T'd into the hose that runs from the oil seperator to the intake... one hose T's into this hose and on the out side of the solenoid runs to this charcoal canister.

I see how you want to just eliminate any foul air in through this connection under the throttle body boss. so, plug that, right. now the system is lacking any vaccum or pressure, so how does this affect the pcv system?
Do you just run a hose from the oil seperator to the catch can? and another hose from the can to the pcv solenoid? then run a hose from the out side of the solenoid to the charcoal canister?

How do you bypass the pcv solenoid problem?

I want to eliminate any foul air from entering my engine as well, and don't have a prob with venting it out into the atmosphere, but can you tell me how to route the hoses involved?

Thanx Zip,
Tony

AllMotor, I ran the purge cut solenoid hose straight under the TB of the JR manifold. Just get rid of the tee. The PCV (from the oil seperator box) and valve cover vent hoses both went to each side of the JAZ breather. Voila, no more oil into the engine. The breather will still let air circulate in the crankcase, when crankcase pressures exceed atmospheric pressure.
