Oil Catch Can Question
 

Hey everyone, I'm planning on getting a catch can before it gets too cold outside to install it but before I do I had a few questions.

I'm looking to buy the SURE oil rig, but it doesn't come with a check valve. Now I know that the reason you need a check valve is because the OEM PCV valve doesn't seal 100% when under boost. Will not having a check valve reduce the efficiency of the OCC, meaning it will allow more crud back into the intake? Just curious because the car operates normally with the leaky PCV and most of the OCC kits can be had with or without the check valve.

Also for anyone who has bought the check valve separately what valve do you use? I know some people have used a second PCV valve, but others have cheaper check valves that work equally as well.

def get a check valve

dont use a second PCV

buy this check valve and hose barbs from mcmaster

Mazda and Mazdaspeed Oil Catch Can by Corksport

Corksport is an option too, it's a little cheaper than SURE and you can get a check valve through them for $10 more. It is only listed in the Gen 2 section for some reason and I think that's what the install instructions are written for. Genjuan should be pretty close, but if you've got a MS6 you might have to get a little creative with the install. Or contact @MATT DAMOND, not sure what his kits go for, but people seem to be happy with them.

Thanks for sending that link, seems like a nice price to pay for the whole package

just get this with the check valve; done.

I recommend the @MATT DAMOND kit.

DM | OCC Kits

Why does the MD kit have the valve on the manifold side but the JBR has it on the block side

You want the check valve on the IM side so you don't pressurize the OCC.


Tapadatass

right, so i wonder why JBR's is the opposite

Just ordered the Matt D one. Looking forward to installing it.

Ok, so I see that there are 3 different versions. Just different mounting points. Is the Version 1 the best solution if you have/ or will have a FMIC?

i thought the CS Catch Cans were getting there tops blown off... has this been fixed? thought the tops weren't welded.

Yeah, the tops are blowing off the cs cans. They are revising the design, but I think the problem is either their install instructions or people not using check valves because the can shouldn't be pressurized. Contact Matt Damond or Jbr, I haven't heard a single complaint about them.

You think exactly what I thought until it happened to me-

There SHOULD not be any need for a CV with the corksport OCC setup due to the routing.

I haven't done much research into it, is their routing different than jbr or MD?

Tappin'

Yes, with their routing the OCC should never see any boost. They have you cap the intake manifold and route it to what used to be the factory valve cover vent which is pre-turbo and should only see vacuum in theory. Hence why they no longer offer a check valve.

Installed my Matt D. OCC today. I didnt take off the hose on the pcv valve but kept it there since I could not get it off, I used a hose barb and connected the oem hose that I left to the hose in the kit. Took me a few hours but no leaks, no cels, and I'm happy about the install. Drilled a hole under the engine tray for access for draining also.

hi,

i'm sorry if this is a dumb question, but which line do you guys use OCC for - the head cover venting, or the oil pan pcv??

Damnit, I wish I knew this when I installed my OCC. Stock PCV ftl. Ordered check valve. Thank you.

+1! I love my Saikou Michi. Only weird thing, on the bottom the drain valve is reverse threaded. I always double check to make sure it's closed after I drain it.

Crankcase venting. You can use a second OCC for the valve cover vent if you like though.

Does anyone know if Matt Damond is still in business?

I purchased a catch can from him in April...I haven't heard anything from him. I've tried to call him a few times and left messages, I haven't heard anything back.

Thanks.

@MATT DAMOND;

He's alive (AFAIK) I've heard he just gets really busy but once he makes contact with you, you'll get it fast.

ok thanks

I was told that he is back ordered on his OCC kits, but in the process of getting more. @MATT DAMOND; is a great guy and definitely still alive!

His OCC supplier, Saikou Michi, said they were really backed up with orders last time I talked to the owner which was about a month ago. That might be part of the delay.

I sure am! My phone line has been acting goofy lately, and only taking messages. Feel free to call me at 630-639-6291

I am indeed very back ordered at the moment, due to suppliers. If it was up to me, I'd have everything stock piled, like if the world were to end.

In for a Damond/saikou OCC, my favorite to date. Great CV included.

Sorry for any trouble I may have caused.
I'm new to MS3's and started getting worried when I couldn't contact you.

I guess I do have a question about the OCCs. How long does it take for the Intake Valves to get crudded up? I heard the Audi doesn't take long and would like to avoid any associated IV servicing.

It's surprising that if that's how simple the fix is, the factories don't just install them at the factory.

Oil catch can
 

You guys that already have catch cans.....did it cut down on blow by out the tail pipe ....if so , by alot or......? And which one do you have ....I was thinking James Barone.....just wish it had a dipstick or something to see how full it is

you shouldn't have "blow-by" coming out your pipe.

If you mean soot/carbon... then it will not remedy that either. A tune will help it.

Read up a bit more.

How do i purchase an OCC from MATT DAMON? Thanks

I'd call his agent. He probably handles all of Matt's mundane tasks. Dude is probably busy with his acting career.

However, if you want a @MATT DAMOND; kit I'd look at his website here or mention him, as I just did.

what about this catchcan:

Large VMS Aluminum Oil Reservoir Catch Can Tank with Breather Filter Baffled Red | eBay

It has a breather filter on top. Is that supposed to be an alternative to a check valve by allowing it to vent to atmosphere?

You need to research more.

I'm pretty sure it was determined that breather catch cans did not work with the DISI. Stick with the tried and true method, sealed can with a check valve, you can't go wrong.

http://www.mazdaspeedforums.org/foru...a-kits-139842/

Yes it's not uncommon to have a vented can. However, if your not careful of how you route it you could end up with a huge air leak. If your going to route it back into the intake side, you don't want a vented can.

The check valve is used when you run from the crankcase to the intake. That way your not boosting your crankcase and oil catch can.. lol

There is a thread that goes into great detail about oil catch cans vented/non-vented. You should read up more on what route you want to go.

Thanks for the additional info.

wtf first of all you fucks are confusing two different types of occ's.

you cannot run a vented occ from IM to PCV because you will cause a massive vacuum leak. (pull)


You can run a vented OCC from valve cover (push)

for that matter you could just stick a hose on there and point it down.

You need to take your meds...you have not achieved the therapeutic dose.

Hello dead thread!

one question about the JBR vented catch can (stage 2) , i have it already installed.
Right now i have this kit installed on my car, but there is oil leaking. Only thing i could think of is the drain valve is open. but when i "closed it" if it was opened in the first place, it caused my turbo to leak :S..
i got oil all over my turbo and got a lot of smoke going from my exhaust

I will lift the car on Thursday and change my clutch so i'm asking, which if these catch can drain valve is closed?

also the check valve, where should it point? toward the catch can or the PCV?
my routing is at states in the manual. one tube is going to the PCV and one is going to the valve cover from the lower point of the catch can with a T connection, and the top exit on the catch can is VTA

thanks in advance

@leka; you have your routing all wrong, it should be from the crank case to the cc then to the intake manifold. check valve goes to the intake manifold, lets air go into it.

I'm running vta, I'm suppose to run it to the valve cover

So your running both the crank case and valve cover to a T then to the CC, then to a filter at the CC for VTA. You don't even need a check valve in that situation.

No, I'm running as I wrote before, PCV and valve cover as a T connection. crank case is closed.

But as i'm thinking right now i think I have the check valve toward the catch can, and need someone to correct me if it is wrong.

also as the pictures shows, left and right, which of these are actually closed?

Crank case closed is wrong. that's why your blowing oil into your turbo. Also a T for pcv to valve cover makes no sense. your trying to pull all the pressure through your crank case is dumb. that and the T means your not filtering anything, it's going straight back into the intake.

Thanks for the reply, but this picture is taken from the manual

The crank case is closed, and it's runing to the pcv and the valve cover. Also I actually have oil runing inside my fmic piping. And I do not have a valve cover connection to the intake

Once again, wrong. Uninstall everything. Actually try to read the directions when you try to install it again, cuz your all kinds of fucked up.

I feel like fucked up.. could you be kind and tell me the routing including the check valve with the vta please? I have the version 2 of the jbr. I feel lost with this manual.. [emoji45]

http://www.jamesbaroneracing.com/sup...nstruction.pdf

Read those two. I don't know what instructions you got, but this will be a start.

Basically you will block off the intake manifold port, route the crank case and valve cover together to a T then to the CC and then the CC will go VTA. READ READ READ.

Also I would just take out the Check Valve, it's useless now with VTA.

I will probably make you mad. But I miss understood the pcv is actually connected to the T on the catch can and to the valve cover. The intake port is blocked.. but I think the problem here is actually the check valve is wrong direction. Would that have that effekt on the turbo?
And I'm sorry for that miss understanding. [emoji53]
Just need to know the direction of the check valve.

Regards

Yes, it would because it would block all air from going to the catch can.
if your not going to remove it. make sure it is facing toward the catch can.
And yes pressure building with nowhere to go in your engine is bad, for everything.

Ok, so I will remove the check valve, if it's as you say, useless. But you could not tel about the drain valve which is open and which is closed?

I have 350whp mazdaspeed 6 and i don't know these basic things, I shouldn't have this car [emoji52]

Right tight, left loose.

Why run the vented setup?

If you're running a crazy amount of hp over stock, it relieves all that extra pressure better

haha yea I know. I think OP would be fine with a sealed configuration though. I had just one sealed can when i had my gtx3071 at ~400hp and it worked perfect. Now that I'm built I am running dual cans with the perm plate just to be safe.

To clear things upp, when the threads are visible on the drain plug, it means that it is closed, and when not visible it's open.

That sounds like quite the nice setup. I guess a vta might be functionally comparable to that, but less money?

QUESTION!!! i just bought a helix catch can (check valve included on the side) i have no bracket, bought it second hand but in amazing condition. now i need to know the thread size/pitch for the bolts and locking nuts to mount this fcker. the bracket i can bend and make myself with an aluminum flat bar.

08 MS3 JBR short ram, straight piped exh

Is you question that you need help figuring out what mount and hardware you should fabricate?

I ended up using two of these to mount my CC:
http://www.siliconeintakes.com/liqui...ket-p-715.html

2.5"-5.5" diameters available.

Yeah but actually forget that. I'll just cross thread or drill new holes and fit them. No one has a straight answer about installing a catch can. The stock pcv on an 08? Why do you need one at all after having a catch can with check valve attached. And why does corksort show hoses from the bottom as normal and then a third hose from the valve hose down to the catch can as well. I mean what the fuck????!!! No one has one fucking solution and straight answer

I used JBR installation guide to mount mine, check that one out.

Just bought my genpu ms3. Previous owner provided a cozmic vented occ that isn't installed yet. Is there any advantage or disadvantage to running that as opposed to something like the JBR occ?

Vented catch cans only work with strategically placed check valves OR if the entire crankcase ventilation system is isolated from the intake system.
