Haney Motorsports Catch Can / Separator / Breather / PCV filter

06VistaGT · October 27th, 2009, 04:49 PM

came out looking pretty good. Thanks for the pics.

Q's07RFGT · October 27th, 2009, 07:16 PM

What hoses are you guys using? I used 5/8'" heater hose and the hose collapsed on itself while at idle. I was looking for reinforced hose, but could only find the clear tubing which would have looked terrible IMO. The hose I am using now will not collapse on it self, but the hose looks a little out of place and want to get something a little more flexible and looks better.

Anthony05GT · October 27th, 2009, 09:17 PM

With my Whipple set up 3/8'' pcv hose was what I used. It fits inside of the larger hose and tubing that was already on the car. I'm not completely sure that it won't collapse either, but I'm keeping an eye on it.

Some guys use hydraulic line from a farm-supply shop.

My Kenne Bell came with an oil seperator. It is not a catch can, but has a clear glass tube that you can unscrew to empty.

06VistaGT · October 28th, 2009, 11:10 AM

is the slight collapsing of the hose ok, or just not acceptable at all? That oil separator was good thinking on KenneBell's part.

Dave08 · October 28th, 2009, 11:20 AM

If you are talking about my air intake, it is molded that way, not collapsed.

NO...your separator feed-hose (PCV line from DS valve cover) appears flat on the leading edge in the pic.

OK, I've been following this thread here and there and haven't commented on anything. I've been vocal on a few other threads explaining this but it seems like we need one more shot at it.

For those that are confused as to why they get oil spray on the passsenger side when that is supposed to be an inlet for the system? There are folks out there that claim they get oily residue out of the passenger side and I was one of those. If the passenger side is an inlet only, how do you get oily residue on your throttle body? The drivers side PCV tube re-enters your system past the throttle body and shouldn't effect the throttle body.

On the drivers side valve cover there is an actual PCV valve. This allows the gases to only travel in one direction, out of the crankcase into the intake manifold. That we all understand and there is no issue. Either a breather or catch can set up will work here.

On the passenger side there is no valve to control air flow. The inside of your engine is a very dynamic environment. Sometimes the crank case is under pressure and sometimes there is a vacuum. Now when this fluctuates from vacumm to pressure it sucks air in through the passenger side and out the drivers side. This we all understand and there is no issue. Having the valve in one side helps facilitate this flow in one direction.

Now there will be times when your crank case is under pressure for longer periods of time and yes it will flow out the drivers side pcv valve. But at the same time how does that PCV valve actually work. If you have pressure from one side it will not let it through, but when you have pressure from the other side it lets it go through, right? Well what happens when ther isn't enough pressure to get the valve open? It will vent through the passenger side where there is no valve to control direction. Also under times of prolonged positive crankcase pressure the blow by gasses will go out both side valve covers. Now also in this situation the air coming out of the drivers side has to go through a valve and this acts kind of like a baffle and may catch some of the oil like a catch can, where anything coming out of the passenger side is straight from the crankcase. This is why some people seem to experience oil spray worse from the passenger side than the drivers side. This is why people get oily residue on there throttle body.

I understand that the way the system is set up and under normal conditions the passenger side is an inlet for the system. But how many of us drive under normal conditions with a stock set up? I thought so.

So, bottom line, catch can systems will help remove oil from the PCV system but also should be run on both sides to completely eliminate the oil from the system.

I am a firm believer in the breathers. It's the way Ive done it for 25 years. There are reasons why you don't want to run those gases back through your engine but that has been discussed already. And yes, with just the two valve cover breathers I was getting some oily residue from the passenger side. But with the addition of the oil cap breather it gave more ways for the pressure to be relieved and thus stopped the oil spray from the passenger side breather. Plus they look good.

The ideal set up to me would be catch cans to breathers venting to the atmosphere.

Coulda sworn I saw those somewhere....

Thanks for speaking up, I thought there was a valve somewhere in the system, but couldn't find it in the PCV tubes I took off for the breathers. Didn't think to inspect the valve cover fittings.

I'd think the ideal setup would be a vacuum pump switched from a certain engine speed and vented away from wherever in tarnation that cabin air inlet is, but from what I've investigated, pumps that don't seize up due to the blowby eating their seals run at least $500.

Yes, Ideally it would be nice but I don't think it's necessary except for an all out race application. And yes you would have to hook it up so it wouldn't be on all the time because too much negative pressure is just as bad as too much positive pressure.

If you are having problems with fumes, a catch can to breather would work but you would have to plumb the breather outlet somewhere where it wouldn't get drawn in to cabin.

That's a good idea, doesn't even need the catchcan, just a breather mounted out of the way... but I'd be worried any extra length hose would make it harder for the gasses and crap to travel -- kind of like too long a snorkel and it makes it harder to breathe underwater.

It's not really an issue with the PCV system since it has slight vacuum from the design, but... I dunno. Maybe a real short run would be all it takes.

Any idea where the cabin air inlet is in the engine bay?

Q's07RFGT · October 28th, 2009, 03:11 PM

On the passenger side firewall, almost right behind the battery. There is a plastic shroud on the top of the firewall, remove the cheesy plastic fasteners and seperate the shroud from the body to get to the filter.

Awesome, much thanks and reps to you!

06VistaGT · October 28th, 2009, 05:31 PM

any hoses a person can get that won't collapse? I haven't noticed mine doing but someone else was talking about it earlier.

Q's07RFGT · October 28th, 2009, 06:22 PM

EfylSetaf - thanks for the reps, is much appreciated.

I used washing machine hose. It's 1/2"id and defiantly will not collapse on itself. Only thing I do not like about it is it looks too big IMO and is very stiff so it will not bend. Here is a pic..

Black Baby II · October 28th, 2009, 07:02 PM

For you guy's running with a can set up, you will need fuel resistant hose or it will eventually collapse and breakdown. You don't want heater hose !

Anthony05GT · October 28th, 2009, 09:59 PM

That's exactly right^

millertimeman501 · October 29th, 2009, 12:22 AM

Been reading all you guy's post on these catch cans. I want to say thanks for the help. I ordered one & will let you know how it works. I would like to post some pic's if someone can tell me how. A big thanks to DiMora & Anthony05GT for answering my questions. NICE FORUM. BTW this is the first forum of any kind I have joined. Thanks! M.
