Calling all MS3 Owners with smoking Turbos...

Gonna try to have it changed out this weekend
Engine replacement at 29K??!!!
Took my MS3 in yesterday for the 'smoking after extended idle' problem. I mentioned the turbo issues people were having, and showed the invoices from a couple of people that posted here. Later that morning, I was asked for receipts for oil and filter changes, since I hadn't had them done at the dealership. This is the same place where I had taken my RX-8, had extensive warranty work done (including an engine replacement at 42K miles), and had never been asked to show a receipt. Anyway, I said I did not keep receipts because I did not have the car serviced elsewhere, but did all oil changes myself, and only wrote down in the book what the mileage was and the type of oil and filter. I guess this must be a sign of the economic times.
In the afternoon, I was told that they needed to do a decarbon procedure on the engine, and couldn't do any more until after that was done. I scratched my head over how a carboned up engine might cause these symptoms, but said OK. (Also, I only use 93 octane Shell, so this seemed pretty ridiculous to me). Today I called them after work and was told that they needed to replace my engine! My service advisor was still trying to find out more about what would be done, but he said in all likelihood it would be a remanufactured engine, although there was a possibility they would pull one off the assembly line. I asked him to get more technical info about what tests/observations resulted in this decision - he said he'd get back to me tomorrow.
He's being told by Japan that this is only the 3rd Mazdaspeed engine ever to be replaced under warranty (anywhere), and its only the 3rd Mazda3 engine ever to be replaced by this dealership. Japan will probably want to get hold of it and do some tests/breakdown.
I can't believe I'm about to have an engine replaced on my 2nd consecutive Mazda. My car is bone stock, with the exception of a K&N air filter and a rear motor mount insert. I do use only Mobil-1 5W-30, so maybe they're interested in the synthetic aspect. Anyway, I'm flabbergasted. They said they ruled out the turbo on the 1st day - I was sure that's what it would be, based on others' history.
Just thought I'd share - this has been an interesting thread, and I have a feeling it's about to get more interesting.

According to my research, Hitachi-Warner did have a defective production run with their K04 turbos (the seals) which Mazda installed on their cars. Mazda did not do a recall because the issue was hit or miss... Out of all the cars they sold, only a few have come in for warranty work, quite a few have been turned away due to mods. So, since the issue has not been a major one, Mazda is probably clueless of the severity. I've met a few owners with smoking MS3s (light smoke at idle) totally clueless of the issue and just ignore it...probably thought it was normal. (screwy)
I guess you can understand why I'm asking this - what did you research - where did you get this information? I want to make sure my dealership goes down the right path with my car, and I don't want a new engine unless they can tell me exactly what they determined to cause the smoking symptom. If you have something I can point to, or a range of VINs affected, I'd appreciate the info.

better try it it can save a lot of hassle and problems post what happens after change

mine started smoking a lil after 7k now im around 9500 miles im using royal purple 10w30
I noticed you have a 35r. Is it still smoking with the upgraded turbo?
Got more info today - the engine is being replaced after a compression test and leakdown test revealed low compression in the #3 cylinder. An engine is being pulled off the assembly line. Looks like I'll be driving our non-turbo 3 for a while.
I really hadn't noticed any problems (other than smoke) with respect to engine performance, acceleration, etc. In fact, my mileage has improved recently, so much that I was wondering if some other maps kicked in at a certain mileage.

i have been meaning to change that i got half way threw putting on the 35r when i decided not to lol im just trying to sell it now
wow Mazda sure took the long way around on solving the problem, but you get a fresh motor. And i guess that answers alot of questions for folks here about the other possible causes such as throwing oil back into the intake tract or maybe the need for a catch can? Thanks for the update K!
Engine replaced, NOW they're replacing the turbo. Apparently it still smoked with the new engine (just like I thought it would). Hopefully I'll get it back Monday.
LOL, I bet they feel like the biggest morons right now...

Man....those guys don't have a clue.
If I were you...after I got my car back I would avoid those guys like the plague. That is...unless your turbo starts again. Then woohoo...new engine time again.lol
Just thinking out loud here: (bear w/me)
Could it be that maybe the smoking is due to a faulty design of the MAF location in relation to the recirculating air from the PCV valve or BOV inlet tube.
The only reason I am think of this is because I used to own a DSM and the BOV dump had a tube that ran down the intake track and pointed towards the turbo. This was to keep the air from being counted twice by the MAF sensor. We used to cut out this tube and remove it from the inside of the intake leaving more room for air. But the problem is that it would smoke after idle, and when you shift due to a puff of air going back up the intake and passing over the MAF sensor. Essentially being counted twice.
I dont really know the layout of the intake with all the recirculating inlets for the MS3 but it may be worth looking into.
Basically make sure that no recirculating air is getting counted twice by the MAF because that can cause a smoking problem in my past experience.

The air dump from the BPV is post-MAF, IIRC.
Are you referring to oil smoke or gasoline smoke? It's possible to get black (gas) smoke when running under a really rich condition such as if the MAF is metering more air than is entering the engine, but this discussion is related to failure of the turbo seals (blue/oil smoke).

That correct...the BPV dumps post MAF. It is counted for in the ECU tune, but not metered twice. Thats why when you run VTA, you get popping and a rich AFR in between shifts. The ECU is expecting the BPV air to be recirculated.
It is possible to blow black smoke at WOT in the upper RPM range. The stock AFR is extremely rich!!!
I know the dump is post MAF on these cars. But when you are idleing or shifting the air going thru the MAF is small so the dumped air can back up thru the MAF (the wrong direction) causing a mis read. I have seen it happen on other cars, that is all I am saying.
Just doing what they're told.
I've got no gripes with the dealership - these days, every move a service department makes seems to be directed by Mazda Tech Line. They just did the tests they were told to do, reported the results and took the action directed by Mazda. I must admit I'm surprised Tech Line didn't pursue the turbo route initially, considering that there must be a history by now...
