parts needed

ebay occ or just a cylinder whatever works, and something you can stick a filter media in.

fittings - pepboys, vatozone etc.

SS teel scrubber pads - walmart etc

breather filter - ebay (our valve covers are i think 15mm? their alot bigger than the standard breather filters they sell.)

5/8 hose (i think) - pepboys vato etc.

assorted tools, taps etc.





tap out the holes, rinse shavings out and shove the SS scrubbing pad in there.





mount with a worm clamp or whatever, sure your smart you can figure it out. you could self tap a plate or screw a bracket into the fire wall, i mig'd a plate to the strut tower

man you suck at diy instructions lol where does the second filter go that you got on the table ?

[Joe Isuzu]

didnt use it, normally im a bit better with instructions but this was something i felt is more custom than anything. just pointing in the right direction

[Sid3wayS]

So your basiclLy putting a breather on the cover with a cc in between
What did you do with the inlet on the intake, just plugged it?

[rigor]

you realize the steal whole will rust fast, turn to shit and get sucked into the mtr lol unless it is stainless whole

[Joe Isuzu]

sorry its stainless forgot to add

i have a custom intake but on my old setup i just plugged it

[Joe Isuzu]

OP updated

[Bosox]

Lol... he said "steal whole"

[GLORIFIEDBOZO]

Man you have such a great prison sex voice

[supersswa]

can you please tell us lil bit more about the installation?
really interesting info

im looking to get new ventilation kit from dealership but i already have some mods that i cant really go back to stock so
i dont think dealer wont let me install that shit

line from valve cover -> catch can (with hole or some type of breather)

[supersswa]

no line from intake like stock ? no vacuum line at all?

sorry im so noob

[Joe Isuzu]

no, aslong as your engine is drawing enough vacuum through the pcv you can vent the valve cover.

[supersswa]

how do i know if theres enough vacuum from pcv and

I have installed ptp pill to prevent smoking do i have to take that off before installing occ?

and can both pcv occ and valve vent occ can be installed at the same time?

[radbrad]

I just added a second catch can just like you did. I was about to do a little filter like you did, but wouldnt that be pulling in unmetered air through it? Thats why i did a return line to the tip..

[Joe Isuzu]

No vent valve is positive pressure, hooking it up to the tip aids in evacuation from vacuum from the turbo however you will be shoving ccrank case gases into the turbo which over time can damage the fins when the liquid condenses back into oil and gas hence why yu put a cc in between

[dot584]

This sounds like a good idea Ill have to get to it one day. I am also interested in how to know if your pcv is working properly. Are there any signs to look for when logging?

[Joe Isuzu]

Blowing dipstick/ smokey turbo

[dot584]

I made a custom occ and I actually stuffed it with the exact same thing you did last year. Like 3 packs of those scrubbies and it works great, no smoking ever and the return line is clean. The line coming into the occ gets gunked though still so I clean it every once in a while. Never blown a dipstick so I guess its working.

I will be doing this one shortly thank you!!!!

[Voltwings]

Daddy Chinkus How full of wool should the CC be, like stuffed or just enough to fill up the empty space?

Quick question, you said second. As far as i know, most go between the PCV and valve cover. If you have your valve cover going to a vented can, what is the other half of the one connected to your PCV connected to, your intake?

no no, pcv valve is located on your block, where it gets its vacuum from the engine via intake manifold. although the vent valve on the valve cover and pcv valve are both part of the pcv system, the occ on the valve cover does interact with the pcv valve at all.


if you guys are interested i can build yall one

Pretty sure I asked you how much you wanted for an OCC when you had your partout :p

Let me rephrase my question, and i don't know why this is just not making sense to me -_- long day at work i guess. Assuming i have one OCC rigged up as this thread demonstrates, with the valve cover being vented, where would one mount a second can, as he described?

Thank you, goodness, i don't know why this has been rocket science for me haha.

[supersswa]

i guess it doesn't have to go back to intake?

just valve cover to occ?

is it required to get a new tune then?

it *can go back its up to you. no you dont need a new tune

[aaron_-01]

Do you think one could tie this into the " making your OCC a 3 port venturi" setup?

[Joe Isuzu]

theres no vacuum in the vent valve, only positive pressure however at wot you may utilize the exhaust

[world famous z]

no vacuum only boost from the VC port? That's not at all what my Mazda Master techs have told me when I asked them about an OCC setup in the past... care to explain? Maybe I'm thinking oranges to apples..

[Joe Isuzu]

The stoc k setup utlizes the vacuum from the turbo to draw crankcase pressure, however there is no vacuum from the vc itself. Its also not "boost" just positive pressure, although if left clogged can create enough pressure to launch the dipstick

[world famous z]

thanks for the clarification, that makes sense.
