I have never heard that before..Ive even read that a dealer tried to void a warranty because the owner put 5W40 in the car when the car requires 5W30.And you say they where putting in 10W30 also?What the hell!They said it recommends synthetic now,SInce when did this happen..This newes is a first for me...Maybe your dealer just puts in what oil they have in stock at the time..

i got an 08 with a smoking turbo after vibrant dp back exhaust. smoking went away(so far) after i fixed my cai. the coupling was half way off on the bottom. Ordered the pg reworked turbo as well

Yea, I made a thread wayyy back and asked if 5w-40 would fuck up the the car.

It's not the one they have at the time since I'm on my 4th or 5th oil change since they've switched me over to 5w-40.

At the initial change I called up my service guy there and basically asked why they changed the oil type and that's when he said that's what mazda recommends as synthetic oil...are you getting regular oil or synthetic?

the only other thing I could think of, is if it depends on the region as it gets really hot here.

how much of a smoking issue (little bit when sitting at a light or smoking out the neighbourhood)
and how long since you fixed the coupling

Here is a little update on mine.

I couldn't stand it anymore and went to AutoZone and got the OEM style PCV for our Speed's (surprisingly they had one in the back) and it looks identical to the stocker.

I decided to re-do my catch can as I had also figured out a shorter route for the hoses where it was relatively a straight shot to the can where before I had it drooping down to the plastic under tray and then coming back up to the can.

All total I ended up cutting out over a foot and a half of hose between the two lines and it looks much cleaner as well.

When I removed the inlet line from the OEM valve and let it drop down I did get a small amount of water that poured out of the hose that must have been stuck down in the drooping section of hose.

I also tightened up the lines attached to the can and did the install this time with the PCV facing straight down as it is for the OEM valve, this differed from my other PCV which was on an angle going up to the intake manifold.

I looked at other PCV's at Auto Zone and noticed that when you lean some of them a little the valve becomes unseated and will not work right...I'm wondering if that was not the problem...it's such a toss up.

Anywho, after a warm up drive I got into the boost a couple times and brought it back to idle for about 10 minutes, which is usually plenty enough time to get the smoking to start up and then I'd hit the gas and send out a big ploom of smoke, well this time no smoke was coming out of the exhaust...after 10 minutes I hit the gas and nothing!!!

I hope this was the end of this craziness, but I will update you further and let you know what the deal is.

Thanks for all your help guys!

[pidass]

yea orientation is vital for the OEM PCV valve to work correctly.

Do you know the part number for the OEM PCV?

Thanks!

[pidass]

L3K9-13-890 it's like $12 from the dealer.

Yep, but if you can get it from the dealer, it's OEM and it's cheaper. The one I got at AutoZone was $19 but I didn't care because I needed to do something right away and they had it on hand.

On the flip side of this rebuild, yesterday I didn't see any smoke but I can only imagine it was because it had cleaned itself out when I was going for the warm up run.

After getting home today from work I let it sit in the driveway and run for a good 10 minutes and it started to smoke. It started out slow and then got a little heavier as it went, I blipped the throttle and it blew out a decent amount of smoke but by no means was it a smokescreen like before...so still, it is improved but still smoking.

I had mentioned previously that I had a CEL thrown but I am not sure if that was also a byproduct of the PCV deal, so I unplugged the battery to clear the code off and I'll see if it comes back on.

If it does then I'll have to take it in I guess.

[martyxattack]

i havent smoked in the past 2 days. dont know if im just lucky or after 2k miles the 5w-40 is making a difference

[GQ_WhiteMS3]

I'm not smoking but to avoid it ... I was in at the dealership for an oil change and asked them to use 5w 30 instead of the 5w20 they very adamantly want to use. They said rather then the 5w30 to relieve / stop the smoking mazda has told them to start adding BG MOA, an oil additive shown here BG Products, Inc. ... anyone know it, use it?

they aren't suppose to use 5w-20 in the speed they recommend 5w-30

[rodrigo]

I am part of this club , I became an avid smoker when my dp went in, yesterday i fucken engulfed the motherfucker behind me at a stop light in pure white smoke....it is embarrasing and dangerous if any cop is around. i have been running 10-40 for months...that didnt kill it. oh well......if u roll up behind the nator mobile....pray we dont stop..u WILL be smelling shit within 2 minutes.

LOL...I know what you mean..When I came back from the dragstrip I was leaving smoke screens at every light...I felt like a ass in a new car smoking up the streets.

[mazspd6]

I can't believe we haven't had anyone figure this shit out by now...sucks!

Upside is that my CEL has not come on yet after three days since the re-do on the PCV to catch can set up, usually it would come on the next day, so obviously this time it's right.

[kgb]

Ok...after much deliberation and thought, I've decided to go with 10w - 30 amsoil for my next change. I am currently using 5w - 30 amsoil, but with smoke.

The reason I've decided on this is: 1. I live in Tampa and do not need the thinner oil at startup AND my smoking only occurs during the first few minutes of driving. It doesn't smoke when I am good and warmed up. So I concluded that the 30 weight is fine but the 10w part should be thick enough to help with the cold engine smoking.

I talked this over with a good lifetime mechanic/race car driver of mine and he said to try to find oil that is closer in its numbers that will work for the car...IE getting the Xw - X as close to each other as possible.

But my logic could be wrong...so what do you guys think?

[7mileshome]

I have 15000 miles and My turbo has been smoking like crazy as of late. To the point where I have to fix it. I installed a CC at 9000 miles, and It still smoked. Close to nothing comes out of the CC, ever. Its the damn turbo. And what sucks is the only way to fix it (that I know of) Is to get a ATP turbo. That means you have to get all the other shit to get that turbo to spool right. Damn it.

[thanox2]

or you can rework your old turbo?

[SharkDiver]

my re-worked turbo will smoke from time to time.

[gsrtype1]

Im at 53,000 miles had a test pipe on for 20,000 miles and a downpipe on for about 3-4,000 miles and never smoked until like 2 weeks ago I sat at this light for 10minutes and then saw smoke at the tail pipe... now it somkes pericodiclly when Im at a light or in a parking lot. I went like 5 days with no smoke and then it came back. Its not that much thought not billows of smoke or anything still I'm thinking I need an high flow cat on there and that should stop it hopefully.

[7mileshome]

How bad does it smoke.... is it pillows of smoke? Or just a little bit? When does it smoke, when you are idleing, or accelerating?

I guess what I would like to know is, is it more smoke than before, the same, or less?

[SharkDiver]

It seems to smoke the most when Im just crusing and then let off the gas and a puff of smoke will come out.It dont seem to smoke at idle but I dont let it sit long idling.Since i put on a high flow cat I have not noticed any smoke but I really need someone to drive behind me and see if its puffing alittle and I just cant see it.Its not smoking as much as my stocker smoked before I replaced it.

[7mileshome]

oh...

well usually throwing money at a problem does not fix it.... but I decided to get the GT2871R and figure out what happens after that.

[serium]

oil catch can ftmfw....im still stock for now though so what do i know

[spd frk]

I am in the club now too. I put on about 35,000km in 9 months with my 08speed3. THen 4 weeks ago I put on the CPE catted TBE, and everything was fine. then I put on the CPE CAI, about 2 weeks ago, everything was fine. I already had an RPMC inlet installed about 6 months ago.

All of a sudden 2 days ago I got one small plume of smoke sitting at a light. then yesterday I got 1 largish plume sitting at a light. I have put on about 4,000KM in total since the TBE install. I am now at 39,000km.

Its not at all bad yet, not even daily so I can live with it. But it may become more of an issue sometime soon.

If you are not running 5W40 oil yet then try that and see if it goes away.

Well that turbo should fix your turbo smoking problem..That will be the turbo I go with when I save up some more money.I just spent all my money on a blueprinted and balanced forged engine and a poweder coated DNP exhaust mani so I will be broke for awhile.

[7mileshome]

Damn Dude.... that is going to be sick. I am doing the DNP with the EWG also. If you are doing a balanced and forged engine, why not go with a bigger turbo?

Just curious... why would you invest that much on our FWD cars?!

[Ftaz1]

So all the back and forth has me confused. Some people have gone to 5w40 and the smoking has gone away, while some have gone to 5w40 and they are still smoking. The same results seem to be true for CCs and valves.
Has anyone reaplced the turbo seals, and if so, has the smoking gone away, or has it gone away for some people with the new seals also??

[stormin84]

so i think i solved my smoking problem...i noticed that when i am stop at the lights i would give it some gas, i would get a small puff of smoke and then it would stop for a couple of lights, then come back.
Since i have the ATR i decide to up my rpm a bit to see if that would help, (800 rpm instead of 650 rpm from stock)
So far 2 days no smoke at lights, can't say for driving (going into boost and having some fun with her, i just can't be in two places at once). i'm running 5w-30 and no cc as of yet still waiting for it to be delievered.

The big turbo will have to wait till next year,My re-built should be fine till then Im hoping.I really didnt want to spend another $1500 at this time either.
The reason Im putting the money into the car is because Im pretty sure I have a bent rod. Also the car is paid for and it fits my needs nicely. I have to drive 65 miles each day for work and I get about 26-27 mpg. I can fit all 3 kids in the car with the wife and have room in the trunk also Its pretty good in snow and we get alot of snow around here. It also has some good power for making my driving to and from work fun. I plan on keeping this car for awhile.

If anyone asked me the high point of the mazdaspeed3, IMO its exactly this! Value.

[mazspd6]

Will a GT2871R run on our stock setup or do you need to go with a stand alone to run it?

Exactly what is different between the stock turbo and the 2871 that one will smoke and the other won't?? Seals??

Just considering my options right now.

thanks

[7mileshome]

GT28 is a ball bearing turbo, the A/R ratio is also much more than the stock turbo. But the reason it "should" not smoke is because of the turbo seals.

The GT2871R that the vendors sell specifically for MS3/MS6 will bolt right on to the stock setup. The problem that I have read most people having is boost creep. Here is a topic on that....
http://www.mazdaspeedforum.org/forum/foru...questions.html

[mazspd6]

Thanks.

What we need is a high quality turbo that bolts right up without alot of issues or need for a SB setup and would not cause any more risk of blowing up a motor than our cars already inherently suffer from.

That thread ended without any real conclusion as to what would stop the creep from happening. Did the PG manifold and external wastegate solve the issues?

[7mileshome]

Yes. It will. But before you buy an ATP, research it. There is better turbos out there if you don't mind fabricating a downpipe. I only know what I have read on the forums, and that is part of the problem. The people that were having boost creep issues were trying to go for 18 psi or more. The internal waste gate is the actual problem with that turbo. As you probably know, there is two springs you can buy, the low boost (14 psi, and 14+ psi) So far, the only people I read about having boost creep issues is the ones with the 14+ spring.

If you go with the external wastegate you can weld the internal one, and the ewg will control compressor revolutions, there by not allowing it to keep boosting after target boost.

You are absolutely right about the high quality turbo, and I don't understand how its been so long and the ATP has been the only aftermarket turbo company to design a kit just for the MZR DI engine. Expecally since they aren't even that great.

I was going to wait for a better turbo option to come out, but my turbo is smoking so bad, and I have tried everything else that has been mentioned on the forums.

I'm in the same boat...installed a cpe catted DP yesterday, started smoking TODAY! Not too worried cuz I have a spare K04 for rework, but still...this is why I waited so long to get a DP.

I'm upped to 800 as well...but it still smokes @ idle.

that's funny cuz when i up the idle speed i don't smoke anymore.
i also have a new spare turbo to be rework but i don't know if i'm gonna install it now, since i don't smoke anymore.

Give it a couple of days to let the stuff inside burn off it could be that.

I'll give it a couple of days for sure...and the catch can should be going in soon. But this makes me worry about tracking it on the 31st.

[bova]

i love when the smoking starts people automatically think the turbo seals are shot. this is not the case, if it was you would think there would be tons of blown turbos by now. things that help eliminate smoking:
-5w40 oil
-increased idle rpm
-oil catch can

and i believe PTP has said the oil return line is also restrictive and cause oil to back up a bit which would increase pressure in the turbo forcing it past the seals, this doesn't mean the seals are bad.
