i've heard of many instances where mods are creating this with our DISI engines...I know for certain the ms6 has this and i'm sure since it's the same engine the MS3 will be similar. you should check out the ms6 threads...they may have an answer since their cars have been out longer...sorry I can't be more help

There are many more threads discussing this topic but here are a few decent ones. I am hoping to get a downpipe soon and if this happens to me, I'm definitely taking it into the dealer and hopefully get a new turbo out of it.

Good luck

EDIT: Great post from Jordan @ CP-E

So .. under what conditions will the MS3 start billowing the white'ish smoke from the exhaust at idle that I read about.

Will it do it with RP only and stock CBE?
Will it do it with aftermarket CBE & rest stock?
Will it do it with aftermarket DP (no cat), RP, & stock CBE?
Full TBE no cats?

Just looking for info because some of the pics I've seen it looks kinda embarrassing with the billowing white'ish smoke. I'm NOT talking about
the pig rich puffs of smoke either under WOT, but the WHITE'ish smoke which seems to billow from the tip at idle or revving when aftermarket pieces are introduced.

Tks,
Mike

Unfortunately there is no particular combination of aftermarket parts that creates the white smoke issue at idle. In fact, we have a record of stock cars that have this smoking issue, so it isn't limited only to modified cars. We don't know exactly why the car starts smoking, but the Mazda Techs that we've spoken to unanimously agree that the turbo seals are to blame in one respect or another. And just to be clear, this is not an issue that is specific to cp-e parts.

What we do know about the issue is that first, some cars are affected and others are not. The other thing we know is that high-flow exhaust components exacerbates the problem. However, not all cars are affected, as I know many turboback equipped cars that don't have any issue at all, and know of several stock cars that are. For instance:


This person took his car to Mazda, doesn't have cp-e products on the car, and they agreed the problem was an OEM issue:

Here is a thread with a SPEED6 whose car is smoking, and it only has a Mazdaspeed CAI installed:

Here is another thread where they discuss what the Mazda techs said about the smoking issue. Also, in the third post down someone with our exhaust products installed said the smoking went away after he replaced his turbo:

Here is another member who has none of our products, but still has the smoking issue with a Magnaflow catback:

Hopefully this helps to clear things up, but the problem still remains without an official fix to this day. It seems some Mazda dealers are stepping up to the plate and are owning up to the issue, whereas others are not. Probably not the answer you were looking for, but that's the information we have so far.

yep this will happen with any DP. the CP-E WITH the cat seems to be the only one that has some success without smoking.

 

[ill_eagle94]

Pretty sure the DP isn't causing anything, except allowing you to see the smoke. I bet it's already there but the particles are small enough to get caught in the cat and burn off before getting out the exhaust.

 

[dkswim]

how many miles have you had DP on for, beacuse first week will result in a little smell and smoke from burning off the protectant and wd-40. you might pull off the intercooler and check for oil in it if its been more then a week.

 

[tru-boost]

i disagree. it was oil smoke that my TBE blew. if it was burnig oils stock, the primary cat had have been clogged and oil soaked. this is still an on going debate. i dont care what the cause is i just want it fixed !

Remember how hot the cat gets when it gets clogged. It would burn off the oil pretty easily.

 

[Haltech]

Have any of you with this problem been checking your oil level to see if its dropping at a noticeable rate?

 

[ill_eagle94]

I've had smoke a couple times. I check my oil every once in a while and notice no change. It does not take much oil to make a lot of smoke.

 

[tru-boost]

i taken it you have never seen a clogged cat ! some will burn off in the exhaust. the rest will bake into the cat and clogg it up. been there and done that !! all the nitrous on my old ford probe messed up a ring. not horribly just enough to see smoke on herd acceleration. it had the cat all clogged up in less than 10k miles after the smoke started.

 

[Finkle]

well my car went to the dealer today, its a good thing that i work for the dealer. so we will kno very soon what the culprit is

 

[Gasological]

If you can't see the smoke, it doesn't mean that bad things aren't happening. The turbo seal failures were more visible in the speed 6s, but totally logical they'll show up on the 3s.

Unless you've got a oil protectant that the exhaust system was packed in, there is NO DAMNED REASON your exhaust should be creating smoke. It's coming from upstream, just not being filtered out/soaked up by the cats (since they're gone, or more open). Get it checked, and don't take no for an answer. Too many zoom zoom boom's already.

yeah, def. keep us updated since you work for them they'll prob.
tell you the truth of things, hopefully.

 

[Finkle]

well they checked my car over and said no visible damage anywhere, they are trying to blame my bpv, they say it was kinda pintched and that may have caused it....the master tech said he couldnt call mazda canada and run the vin cuz they were closed so it looks like moday till i find out more news

 

[tru-boost]

that tech is a moron and does not deserve his job.

 

[Finkle]

LOL, wanna know the funny thing he is the MASTER tech too. Hopefully he will figure it out, apparently he said that my bpv vacuum line was basically crimped shut..... but he said that wouldnt do much to the car.
Now the thing is, i was driving home last nite and on my way home the engine light came on!!! now thats just great, imma get it scanned and see what comes on.....the only thing i may figure is that its me not having my cat in the downpipe, but that light shoulda came on earlier cuz ive already put 500km on the downpipe
any ideas????

mine came on recently too and they cleared the code and ran the recalls.

i got the pcm calibrated (4907H)

the shutter valve was checked but was alright...it was the updated valve with "the yellow dot". (4807H)

they also checked for the evap leak and that came back ok also (P0456)

the emissions recall was the one that set off my light. the exhaust seems to be running a bit cleaner but its still to early to tell whether the soot is lessened by any accredit-able amount. i dont know. im getting my TBE soon and ill only have one mini cat and my megan CF can on the back. im hoping i dont get loads of smoke. then again my buddy has a speed6 with the same thing, except dual, and he has no problems...so...(shrug) yours is probably the 4907H recall also if you didnt do it already. i have 10000 and it didnt kick on until about 100 miles ago. hopefully its a quick fix and the smoke stops. or better yet, you get the newer turbo like many others have. (yippy)

 

[Finkle]

my car is a late production 2007, so the turbo design couldnt be much different if any at all
we'll know what it is by tonite

 

[Finkle]

so i got it scanned at the dealership i work at and the code that came up is
P0139......well thats cuz my 2nd o2 is sensing air coming thorugh or soehting like that.....the code is understandable
now to get the smoking issue fixed, the tech i talked to today has already come to the conclusion of turbo, or rings
