Says the guy with the dirtiest SSV ever recorded...

Ideal setup is to have the overflow piping routed past the SSV in the auxiliary teet. That gives you overflow protection, gives you vacuum to facilitate venting, and keeps the moving parts on your intake from getting gunked up by oil.

Everything else is a compromise. I've got my can routed back to the throttle body because that's what I had piping for. You have no exit because your didn't come with one. Some people don't have cans at all.

If I understand that TSB, they are still routing from the the "new" oil filler tube back to the port on the 'accordian' intake, just at a lower part of the oil filler tube, thereby still introducing oil back into the system.....which doesn't alleviate that gunked up SSV. Which is something I'm currently fighting at the moment. i'm trying to hash it out with my service center to have Mazda pay their techs to "properly" clean the intake manifold and I'll pay them to clean from the the extension out to the air filter....or try and do that part myself. My car is well out of warranty, but I know mazda is well aware of this issue and I've had a SSV CEL 3+ times over the past 3 years. 2 of those times were 2 months apart!

Who's been filling your oil?

Happened to be pulling one off a car.... and remembered you.

Instead of capping the intake, Can u put a breather on it. And have one on the catch can as well?

cjkim

no on the intake
yes on the catch can

Oh my. I recently purchased an oil catch can for my '06 RX8. After reading through this thread it mentions that a 2006 RX8 may not necessarily need an oil catch can. Please say it ain't so! Can I actually still use it?

cjkim

yes you can use it
i've heard the "fix" that mazda made was worthless

Proxi

Thanks for the info.

But before I install mine, I have a few questions though. Since I have a 2006 model and have the TSB re-route setup on my engine already:

- So once I connect the hose from the front oil filler nipple to the catch can, what is the best way to seal/cap the two small nipples on the intake manifold/maintenance ports that is originally connected to that front oil filler?

- Also just to make sure, if I'm planning to put a breather on the catch can - I will have to seal/cap one of the fittings on the intake tube AND also the "back" oil filler nipple (as per Kane's post regarding where the "separate line went from the intake accordion tube to the 'depths of your engine bay'.")

Sorry for the noob questions.

cjkim

I have an 04 without the TSB, so I'm sure someone who's done it before can help you

-the two nipples can just be capped with any ordinary vac cap at your local auto parts store.

-back oil filler nipple? not sure what this is referring to since mines an 04, but if Kane is saying to cap it, I'd believe him. yes, cap the intake.

Proxi

Okay. Finally installed the catch can on my '06 RX8. Since my car already had the TSB re-route, I capped the two small inlets at the maintenance ports which was originally connected to the front oil filler. I also capped one of the inlets of the intake tube and also capped the back oil filler (which was connected to the inlet of the intake tube I capped).

Hopefully this installation is correct. Kindly take a gander at the pics and please let me know if all is good on this install. Thanks.

Mazurfer

Looks okay to me.

Great DIY bro.

I have a question though. I have an 08. I attempted to install my catch can last year but when I did I got really bad idoling. Everything was capped and installed as you described. My question is if there are perhaps differant ways to set it up the catch can by year of the 8?

Because if I am not mistaken isnt the entire maf map totally differant from an 08 to lets say perhaps an ealier verision of the rx8? I'm asking because I was/just kinda sort of sold my catch can and would actually like to install a catch can for just in case precautions that it is meant for.

Mazurfer

Not sure, I'll look it up. I didn't think there were any changes in this area until 09, then there is a slight difference. Well..........when you are ready for one, I have a powder coated Greddy on just sitting in a box in my garage all packed up!

is it normal to see the oil light go on and smell oil??? cause that's what I'm seeing lol's.

No, that isn't normal. Double check your oil levels first.

^^ i changed the accordian

very nice diy, going to do this when i get back to the states

So, what is the Benefit of just putting a breather on the oil catch can? Isn't it SUPPOSED to go back into the intake? I recently found a ton of oil in the ribs of my accordian and freaked out.

I plan to do this mod, but just wondering about the adverse effects of not routing back to the intake.

Thanks guys!

I would say there are no adverse affects to not running the hose back to your intake.

Oil shouldn't ever be in the intake, end of story.

The breather is just there to make sure no debris gets into the catch can where it could (theoretically) make its way back into the engine. The filler neck isn't under vacuum or anything, but I wouldn't cap the catch can just because any air will have no place to go.

Mazurfer

Yeah, you've had blow back into the intake and that's exactly what you want to avoid. It will get into the throttle body and could/will gum it all up in due time.
Now......if you route the hose back.........theoretically you could have oil fumes returning and therefore have a little bit of oily residue, so that's why some people just don't even return it to the intake, but put the breather on it. I guess Vyndictive makes a valid point as well concerning not just capping the catch can.
