Oil Catch Can Question

[plak424]

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.

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

I recommend the MATT DAMOND kit.

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.

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

[Tronix]

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

[SC08Speed3]

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?

[jeffdevo]

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

[ASHMS3]

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.

[ASHMS3]

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

Tappin'

[El_Diablo]

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.

[mrQQ]

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.

[DVM17]

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.

[Beercules]

ok thanks

[RedRyderBB6]

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.

[Beercules]

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.
