BMW says to replace all 6 injectors, test proves otherwise, now what?

BeastMode335i · 07-21-2015, 05:08 PM

Also, BMW said they replaced the CCV line because it was leaking, is this what BMW calls a PCV valve..?? I googled it and it seems they get mixed up a lot..

Thanks!

No way injectors would cause smoke like that. I'm guessing your turbo oil seals are toast.

You have to replace the turbos. Since this is quite the endeavor (both time and money-wise), I would make darn sure this is the issue first.

Should I have it towed back to BMW and tell them to check again lol..?? Is there any way I can have this covered under the wastegate issue.. I do hear a rattle upon start up, but being that they said "turbos are fine" I imagined they checked those out...

They charged you $100 to change a vent hose !!!

BeastMode335i · 07-23-2015, 06:31 AM

21 for the hose, 99 for the diagnostic..

What about the thread about people overfilling their tanks and getting fuel in a vent line that terminates to the throttle body? I vaguely remember them stating to run the car low on fuel and then blowing the line out near the intake manifold.
Apparently once fuel gets in , it acts as a suction line and pulls loads of fuel in and causes the car to smoke and stall.

I could be remembering it wrong but worth a try to look at the throttle body/manifold and blow some air in the lines or run the car low on fuel and see if smoking goes away.

BeastMode335i · 08-06-2015, 10:01 AM

Hmm I didn't hear about that one.. I'm at about a half a tank though so wouldn't that excess fuel have burned off by now..?? This smoke is like a vapor almost.. And to make it worse, I just brought my car back to BMW and they were telling me I need new spark plugs when my plugs are not even 2 days old..!! Think it's time for me to put the gloves on and tackle this one myself..

007_e350 · 08-11-2015, 03:02 AM

Turbo seals... One way to check is to remove downpipes and see if there's oil around the turbine area... I'm almost certain that's the issue... at those temps even a little vapor of oil becomes a TON of smoke.... ur best bet is to buy from tomkinson, 5xx a piece and take it to an indy to put em in

ferocity02 · 08-11-2015, 11:52 AM

Are you burning coolant? Is the coolant level dropping? White vapor suggests you're burning coolant/water. Burning oil would be more of a blueish smoke.

BeastMode335i · 08-11-2015, 10:23 PM

Coolant level hasn't budged in 3 months so I'm certain that's not the issue.. Oil level is dropping about a qt. a month however..

How many miles per month, or miles/quart?

All signs are pointing to the turbo oil seals, which is a common and well-known N54 issue.

BeastMode335i · 08-12-2015, 01:08 PM

Yeah that's what I'm figuring as well.. And I put about 750-850 miles per month on my car..

It's not the turbo seals. Too much oïl pressure is created during low rpms and this oïl is beeing pushed through. What we need is to reduce oïl pressure.

PCV you think..??

j1gilles · 08-19-2015, 07:56 PM

I've seen multiple 335's smoke like that with leaking injectors... I would look into replacing the other 3 injectors and changing the oil...

Did change the other 3, also changed the oil a few days ago.. Still smoking very slightly, thinking it may be either my PCV system, or some oil/fuel stuck in my cats.. Car runs fine that's why I only assume it's residue left over..

It's probably just fouled cats... Go beat on it a little bit ?
