Mps exhaust blowing white smoke at idle

[mickyj]

great news Col and good to see Madaz Brutus will be right for the tablelands cruise and we won't be eating smoke following you up the Gillies

Howdy Col, I've been following the thread with interest and stressing along with you. I'm SO pleased that it its all worked out for the best as I can only imagine just how devastated you would have felt, I certainly would have been!!

Out of curiosity, would it be fair to presume that the Gen2 has addressed the root cause of these turbo failures, especially considerring that they are plugging one of these new huffers in place of your old one?

Let us know how it goes......hopefully it's only up and up from here.

GREAT NEWS!

Stressed is an understatement ,yes it would be fair to presume the problem has been addressed in the gen2 turbo ,although you wont hear that officially from MAZDA .
The members on this forum who have had their turbo,s replaced believe that the new one,s an up grade ,the general consensus is that it spools up earlier and is stronger in the top end .
Having said that it is early days for gen2 mps,s and it will be interesting to see if any of you gen2 guys start having problems when you've racked up the klm,s
I believe Mazda has addressed the problem at $4k a replacement which includes dealer labour it would be a financial nightmare for Mazda not to do so

Got that right mate but the down side is you will now be able to read my number plate

Madaz has a new turbo problem solved !!!!

Guys,

Out of curiousity, how much would a turbo cost if we were to pay for it ourselves?

Thanks.

Cheerio.

About $4k includes dealer labour charges

Col it can be done cheaper and faster elsewhere you know where.... Dave and I had a good chat this morning with the boys at Allstar Tuning

Ok thats fine Rino,I was only quoting the Mazda dealer replacement cost as told to me . Allstar would be my first stop . By the way the new turbo definitely spools quicker and seems to pull a lot harder it will be interesting to see the dyno results .

Given the comment above by MattMPS3 (8/11/09) and whose opinions from past experience I have come to respect - re variable pressure between inlet (stock) and outlet (modded) sides of the turbo displacing the turbo oil seals, it will be interesting to see how the seals perform with a fully optimized setup such as my C_S FMIC and TMCAI, and a CP_e catted 3" dump pipe, which one might argue, on the basis of Matt's line of thinking, should equalize pressures on the shaft.

This is an interesting question, especially as the FMIC raises boost over stock significantly, even before other mods such as a Standback enabling extra boost to be dialled in. The additional boost means that one has to tinker with boost optimizing settings in the Standback and the BOV settings to reduce or eliminate compressor stall on throttle lift-off, too much of which, at least at high TPS, is held by some to be harmful to turbos. Fortunately, most compressor stall seems to occur at low compressor shaft speeds and is unlikely to be harmful.

However, any shortcomings in compressor or airflow performance brought about by hi-flo mods may reasonably be assumed to have the potential to reduce turbo and/or seal life and hence affect warranty, if that is a concern, or your wallet, once warranty has expired. But in this case I take comfort from the fact that the stock arrangements are also known to give problems.

And in any event, the stock breathing is so convoluted and restricted I couldn't live without addressing it. Once you get the stock cat out and examine it, you'll understand why. The benefit of the mods undertaken have not only been vastly improved power and response but also economy.

Thank you Allstar.

I also believe that half the problem comes from the urban environment these cars spend too much of their time in, with traffic light squirts, lots of hard boost from zero, lots of raw fuel being only semi burnt, smoked-up cats, cold-started engines never getting warm enough, sooted up plugs, clogged PCV valves, oily rocker cover internals, fuel on bores washing off the oil, especially if BOVs are set to VTA, etc. Most engines I've had anything to do with will provide faithful service at all loads and demands if they are given regular open road runs to clean, burn and dry themselves out.

Taxis provide a good lesson, offering million km runs without strip down. There's nothing special about their engines that enables this.

And remembering that you have to let the turbo cool after a hard run. After normal runs around town, just the few minutes maneuvering into your suburb, street and garage will provide a fair bit of cool down time. Just don't climb Mt Kosciusko flat out with a glowing turbo and turn it off immediately at the top! Let it idle for a while and let all temps stabilize. It's not rocket science.

There has been a few 2010 MPS's with the white smoke problem, and at very low kms. I suggest the problem still exists.

[Doug_MPS6]

At ~$4K a throw, if it wasn't a warranty fix, I'd simply pull mine out myself and send it to Turbotech for a rebuild. It'd cost a fraction of that.

[shinslinger66]

I have seen the MPS turbo's on ebay selling for $250

[Doug_MPS6]

Mazda had no issues with my mods at all when I pointed them out at time of booking in for my service, but then again, I haven't been to them with a warranty issue that might be capable of being attributed to them.

However, I doubt very much that a good well-engineered after-market Dump Pipe would give them the jitters as it is in fact making life easier for the turbo by virtue of smoother gas flow and reduced heat.

Now if there is evidence that you've seriously tweaked up the boost, it might be a different story. An SRI wouldn't fit in that category....

[MPSboi]

Lads, exactly same dramas as mine, my Mps only had 11k kms on it , and once i ftted the dumpy it got worse...thing was i told my dealer it was a tad smokey before i fitted the dp.he made a note and told me to keep an eye on it . he did actually tell me the dumpy and CBE looked the goods, ( full CP-E system) as well as the intake.
He also told me that the CX-7 was bad for it .
Would be good to know if any Gen 2 MPS will have it also


Let us know how u get on .

Time for a new turbo.

[3mpsblack]

hey guys i recently found that my 07 MPS 3 is lettin out puffs of white smoke when i put my foot down, is this the same problem? i dont yet believe it happens on idle but definately when i give it boost while driving..

my mods are CPE TBE and CPE CAI..

also i need to know where a good performance and tuning place is in perth,

thanks, KARL

[shakespeare]

Ouch Karl, best thing is take it to your dealer and ask them to check it out, I have heard of some guys running TBE's with a little bit of smoke which goes away when running a thicker oil eg. 10W-40, though not sure if your smoke is turbo seal related, do you get any weird plasticky burning smells? As that seems to be the common smell with blown turbo seals.

Also haven't used a tuner but a mate who has a Subaru uses these guys and said they're good.

I'm also looking at gettting a dyno done here, as they have an AWD dyno and heard they were good too!

Sounds like the seal is begining to fail under load, only a matter of time before it does it at idle.
