    Some customers may experience white/blue smoke from their exhaust pipes
    after prolonged idle periods and/or while driving in traffic at very
    slow speeds.

    This condition may be the result of the turbo's oil supply not being
    able to adequately drain out of the turbo during long idle periods.

    Vehicles having this concern should be diagnosed using the following diagnostics procedure.
    Repair Procedure


    1. Confirm that the proper maintenance intervals have been performed.

    2. With the engine at normal operating temperature, allow it to idle
    for an extended idle period.

    Caution:
    Closely monitor the engine coolant to the assure the engine does not Overheat.

    3. If smoke from the exhaust is present after the extended idle period,
    take before pictures of the smoke, then change the oil and filter
    using 5W/40 (synthetic).
    After the oil change, in order to burn off
    the oil that remains in the exhaust system, perform the following:
    start the engine, check for oil leaks, then let it idle for 10
    minutes, after the 10 minute idle period, increase the RPMs to 3000
    for 1 minute, repeat idle test to confirm that no smoke returns.

    A: If the smoke returns, contact the Technical Assistance Hotline
    (Select option #2 for Major Assembly Authorization) with the oil
    change history information, to attain an authorization for a turbo
    replacement.

    B: If smoke DOES NOT RETURN after the repeat idle test, NO other repairs
    are to be performed at this time. Explain to the customer that MAZDA
    is currently working on an improved positive crankcase valve (PCV)
    system to reduce the engine crankcase pressures to allow the turbo's
    oil supply to drain from the turbocharger more efficiently This fix
    will be available approximately within 90 days and at that time the
    oil will be changed back to 5W-30 and the improved PCV system will be
    installed


    Sounds like something is on its way for this problem. I searched but couldn't find any info that was similar to this.

    awesome!

    There will be a PCV recall soon? or is it one of those things that they won't fix till it breaks/smokes?

    B: If smoke DOES NOT RETURN after the repeat idle test, NO other repairs
    are to be performed at this time. Explain to the customer that MAZDA
    is currently working on an improved positive crankcase valve (PCV)
    system to reduce the engine crankcase pressures to allow the turbo's
    oil supply to drain from the turbocharger more efficiently This fix
    will be available approximately within 90 days and at that time the
    oil will be changed back to 5W-30 and the improved PCV system will be
    installed

    edit: after the new pcv valve, mazda recommends going back to 5w30. Wonder if they recommend that because of fuel economy decrease and additional cost or because the oil is too thick for the engine...

    Some 2007 MS3's manual contain info that states something along the lines of "5w20 for regular MZ3 engines, 5w30 for turbocharged engines", but the way it reads is confusing. From the discussion in the US, a lot of dealers has it on their SERVICE COMPUTER that all MZ3/MS3's take 5w20...as such, many Jiffy Lubes (taking their cue from the dealers) also has 5w20 listed for the MZR engine in their computers...

    So much for Mazda's recommendation...we look out for our own.

    Not sure if a recall on PCV will actually solve the problem? If the turbo is leaking oil how would replacing PCV will fix the leaky turbo?

    Some explanations from MSF for the switch to 5w40 vs. faulty PCV:

    Quote Originally Posted by bova80

    Quote Originally Posted by Lex
    The reason the oil does not drain well enough is because the crankcase pressure is too high for the drain requirements from the turbo. This is an indication that the PCV system does not relieve crankcase pressure adequately for this particular turbo to work with the existing drain hardware. So this is their approach. Another approach is to increase exhaust back pressure (this is why removing the cats makes things worse), and another approach is to reduce the volume of oil entering the turbo (Bnoons bolt). There's more than 1 way to skin a cat.
    Quote Originally Posted by ToledoSpeed3
    It doesn't [drain better], this is being done to treat the symptom, not the actual problem. Thicker oil is known to reduce burn off. The new PCV system they are working on is being done to address the actual problem.

    Wow... crazy. Wasn't there an unrelated thread on MSF about blown engines and shitty PCV valves? Didn't someone say that Mazdaspeed uses a different PCV system with their race teams? I wonder if the two are related in any way... or better yet, I wonder if this new PCV system that we'll see in 90 days will be the system they use with their race teams?

    My biggest question concerns the date ranges for the applicable models affected.

    Applicable Model(s) VINS
    CX-7 JM3ER ****8* 209008 Produced before 2/15/08
    MAZDASPEED6 ALL ALL
    MAZDASPEED3 JM1BK ****8* 880368 Produced before 2/6/08

    So naturally, I'm asking myself, what did Mazda change in all Speeds produced after 02.06.08 that make them ineligible for this TSB? Obviously, Mazda implemented/changed something in production after this date to correct the problem in the factory...

    cars built after that date had the L3Y1-13-70ZB turbos installed up until 6/30/08... the turbos might say "L3K9-13-700H" on it... the 2nd of the "improved" turbos (but I still saw cars come back in with yet the same smoking issue)... IMO, the ones that should have the least worries are the very new ones... for cars built from 7/1/08 onwards, it came with the L3Y1-13-70ZC turbo (it says L3K9-13-700J on the turbo itself)... from my observations, it looks like the internal oil restrictor (where the oil line goes in) was changed to a smaller one

    I didn't hear or see any PCV valve system changes on any year of these motors though... so no production or replacement parts changes yet

    if you got a turbo replaced already, you might want to check your invoice to see what you got!

    when you get it stormin, you mind letting us see some pics? for those guys who've worked so hard to stop their turbo's from smoking, it's tight that all the work is actually going to prevent me from getting a new/replacement turbo from Mazda, and might make this bnoon banjo bolt a necessity. dude on MSF said it's a bitch to make and eats drill bits?
