I've searched the board ... but I'm still a bit confused. Thanks.

 

not sure if this will help....

but run a hose from your PCV to the can.....and then from the can run it back to the intake manifold

If you look at it now...you will see that the PCV is connected directly to the intake manifold via a dark grey tube.

The valve cover breather is untouched and should route directly back into the intake arm.

 

Okay ... I understand, but what is the purpose of the breather Filter then? Is it possible to route the hoses that go into the intake tube into the can?

the breather filter just sits on top of the can to let it vent further I guess...designs can vary but the primary goal is catching the sludge in a resevoir (which this model does).

can I ask where you bought it?

 

I purchased it at: Jaz Products, 800-525-8133 ... roughly 40 bucks

Still looking for some install advice.

I don't have the same catch can as yours but I thought you'd like to see how I mounted mine. I made custom brackets.

 

I use the SRR can and I mistakenly used teflon tape on the threaded cap and that actually prevents it from venting and so now since the system is pressurized all the which is suppose to be collected in the can gets sucked back into the intake manifold....



Breather/venting good.....

my method.....we-todd-did.....

 

I think I will buy one of those Jaz cans...they are a good price!

Only thing I don't like are those 90 degree fittings. I'd need to pull those for straight ones.....dunno how you could get them to flow facing down like that.

 

This is the best lookign catch can i have seen so far. loks small and compact so it does not take too much room in the engine bay. it also looks like it has a valve that you coul drain the oil out and not have to take the whole can out!!! it looks great. i might just get on of those and its really cheap, but how about the design of the can inside?? i thought i read that it needed to be baffled on the inside?? can some one help and explain?

 

Nice thread.

 

Adam: Is the Jaz can baffled? Roughly how big is it?

 

The mini Jaz catch can isn't baffled. Baffling is needed to help to seperate the oil droplets from the blow-by vapors. Without baffling the oil droplets will not be seperated and collected in the catch can.

The mini Jaz is a 1-pint capacity. IMO, I think that 1-pint is a little to small. If the catch can fills up will driving you will be sucking the oil directly out of the can and into the intake manifold. I would suggest a 1-quart capacity.

I would also recommend removing the filter from the top of the can and sealing off the opening. The reason being, is because the filter will not allow the system to be a closed-system and this will not allow the PCV system to work properly (ie. no vacuum on the PCV valve).

 

looking at that, yeah...I agree

 

This is going in my Race Type R ... so filling the can is not a concern of mine. To be quite honest, I can't imagine someone ever filling this in their street car. Just give it a look over every couple hundred miles. I suppose I will fill the can with steel wool to act as a baffle.

Also, the inlets swivel around and it's somewhat clear in color, so you see when you need to empty it.

Can Someone explain this setup??

 

Or this one?

 

Those setups look whacked to me. The PCV vacuum is created by the intake charge. If you cut off the intake from the system the crankcase will not be ventialated properly. I've seen so many pictures showing so many different oil can setups and the only one that has made any practical sense to me was Tommy_Guns setup. I think alot of people just mistakenly think the valve cover breather is what's shooting oil into the intake.

 

True

Hopefully this diagram will clear it up.

 

This one looks OK to me. You can see 3 hoses to the catch can. 1 from valve cover (not needed IMO). 1 from the intake manifold and 1 from PCV valve, I guess..

 

I don't think you should connect the intake manifold hose to this can. With that filter your intake will be sucking false air directly into the intake.

How about sealing the intake manifold off and connect the valve cover hose + PCV hose to this catch can???

 

Look at that header!!!!

This thread say's to attach the filter to the valve cover nipple.

If I look at the PCV schematic then why not discard the filter on that can? I think DutchITR is right: you will suck in air thru that filter (and hot air for that matter as well).
BTW: I always used to believe that the cover would be overpressure instead of underpressure. Never too old to learn, I guess.

 

does jaz only make the one type of oil catch can/breather?

Took the words our of my mouth.
The oily-air mixture passes through the pvc system because of the vacuum created by the intake. Not pressure created but the crankcase.

If I am wrong and there is also pressure coming out of the crank case, then a filter element on the catch can wouldn't harm anything.
Presurized oily-air is sent to the catch can and blown out the filter.
Then
Vacuumed air from the intake will be sucked from the catch can's filter.

Can anyone confirm that the pvc circulation is only caused by intake vacuum charge?
