Smoke at idle fixes, my thoughts and notes

Seems like i have a 50/50 shot. i have a HT tune so i can only bump the idle up +200( i know i should just get the AP, forgive my brokeness), will that be enough? With all this bullshit being said, will there ever be an end to the dreaded smoking turbo, or is it BT time?

just up your idle and see. why you ask us? see if it works and TELL us!

[DuBz]

no, no, no man. I was looking for,"It'll all be ok," or "just shove a potato in the tailpipe," or "just drive the fucker off a cliff" u know that sort of thing.

[DuBz]

yes yes i know...i talk a lot of sheet

[DuBz]

upped the idle today (+200) and voila! no smoke. I make no assumptions cuz she's infamous for being smoke free one day, then smoking at every red light the next. For the sake of science, I'll hold off on the bnoon bolt n see if the raised idle is enough, then throw it in there anyway for good measure

How has this worked for you? Did you end up needing to buy the bold or was raising the idle a fix?

Thanks!

Bnoon bolt, ptp pill, still nothing... :'( the next step will be raising the idle. It seems to work when I raise the idle myself.

Ive been raising the idle manually at red lights and still smoking like a SOB. Should I even bother throwing an upped idle tune on it?? I have cobb ap but I also have a Mac, ATR is Win only, so if anyone is bored can I get a CS 93oct TIH v200 tune with idle raised to 1050 or 1100 rpms???? pretty plz????? I'm still smoking a ton during shifts and coasting as well. I doubt idle raising will help at all

[RidenDirty]

Hey bnoon, are you still making those restrictor bolts??? If so how much for me to get one from you??? I am having the same problem and would love to get it fixed asap!!!

[G Sp33dy]

added rotella t-6 5w40 + my banjo bolt and still smoking. Unfortunately bnoon the files you sent me are "locked" to your AP ser# and I can't load them, but thanks anyway. I will be using atr tonight to raise the idle and see if that helps. Hope my new valve cover gets here early tomorrow...

IDK if this matters, but while changing the oil today I noticed some oil dripping from the oil drain line from the turbo, leaking down the drain tube, and a small amount was on my plastic undertray and speckles on my drive axle. Has anyone else had this happen? Its making me wonder if the oil drain tube is somehow clogged. Is there an oil screen in there? Idle bump to 1000 rpms did not work whatsoever.

To me it could be a couple of things causing the smoke at idle and they all have something to do with the oil return from the tc, it couuld be compounding issues, but basically it is a pressure issue.
The crankcase vent system not venting properly can cause backpressure, ie a garrett GT series turbo seals are designed to weep once the cartridge chamber pressure exceeds @45psi, it will load the hot&cold side pipes with oil until the back pressure source is fixed. IDK know what the oe ms3 borgwarners are designed to do handle over pressurization....but smoke at idle is a clear signe oil is making it past the hotside seal.

A kinked or damaged return line, I actually had the lining come apart inside the return line causing this to happen, and it was not obvious.

I eventually found the damage of the liner after the fact when I was able to cut the line, clean it throroughly and throw some light down the inside/post mortem inspection, what I did in the meantime was to weld a -10an aluminum bung to the highest point possible in the oil pan, bought a -10 return adapter for the tc and ran -10an oil return line.....overkill but hey I know that fucker has no restriction problems do to size now, then I check the vent system out.

<----- has a non-smoking k04 for sale, with bnoon bolt for a lil extra

Sorry for the noob question but the bnoon bolt fixes smoking or do you have to up the idle rpms as well? Also it swapping to the gt series turbo just a simple swap and does that eliminate smoking all together? I am looking into purchasing one of these cars but I dont want to start modding only to have it start smoking..

From what I have read, it seems like the bolt alone fixes it for some but others need both. I have the bolt and it hasn't helped me any. I'm getting an AP to raise the idle and crossing my fingers that it fixes the problem.

Having the AP is a great mod and can help the smoking issue by raising the idle. I had the smoking issue too when I installed a re-worked K04 and a catted DP. I switched to 5W-50 oil and that stopped the smoking. I have, since then, installed bnoon bolt and switched back to 5W-40 oil and once in a great moon when temps are about 100 degrees I will see occassional smoke. Try the heavier oil first and then get the AP. But eventually get the AP. Guys here love it. GL

^^^ if you're buying, i'd let the car idle for 10 minutes to see if it smokes. the current owner should be able to tell you if the turbo was replaced and / or the vent kit was installed.

i'd use the combination of 5w40, up the idle, and add a bnoon bolt and occ just to be on the safe side. oh, and don't forget to drain your occ.

check out the bt turbo swap how-to's. i wouldn't call it a simple swap.

[boostinp]

So stock if it smokes after 10 minutes it most likely needs a new turbo how much smoke am I looking for?

[karl-hungus]

you're looking for any smoke.

[boostinp]

Cool thanks

[DiGi Faggot]

So i'm curious. If the PCV(is broken?) goes unfixed for a long time and you smoke for a long time.

Could this lead to piston ring failure?

i don't know if anyone has covered this, so i will. Mazda's final smoking turbo fix is the way to go with the smoking problem. i purchased the pt-performance pill thing and it did not work. my car being out of warranty mileage i had to do the fix my self. yes the factory recall replaces alot more then what i did but it works with no need for idle raising or pt pill or the oil restrictor bolt. all i did was go to advance auto purchase a universal vaccum T some 1\2 inch and 1\8 inch tubing just incase you F up (not sure about the 1\8, blah). looked up the diagram from mazdas recall and did it like that. let me know if you guys want pictures or want to give me lessons in writing.

Been there, tried that, didn't work for many many many members. Glad it worked for you.

[zspalm1]

Yep it worked for me I've only had one instance.where it smoked but it was because I was at idle with ac and reving it a little once.I stopped it went away quick though

[Mandinca]

I want to buy one of the bnoon bolts, where can I get one.

I've searched the threads and come up with varying answers so I apologize if the next questions seem redundant.

Do I have to have an AP to set my idle, the dash reads about 900rpm when warmed up, is that the correct rpm to potentially fix the smoking ?

Should I rebuild the turbo while I have the manifold off or just do the bolt and rpm ?

Last thing, I live in CT where it gets cold in winter and hot in the summer, can I still use 5/40 or should I use 5/30 ?
Does it have to be synthetic ? I cover a lot of miles on my daily commute so oil changes are frequent.

Thanks.

[DuBz]

Raising the idle was enough for me, then I switched to rotella and have been smoke free ever since. Some people have good results with 1 of the three fixes, others need to use all of them, and some people just never stop......who needs red lights and stop signs anyways. GL
