White smoke from exhaust (it’s oil)
Hey guys just want to share my recent dilemma , My 2015 M6 GC has picked up the habit of smoking from the exhaust , it started with a small puff of smoke when stopped at a light or stop sign , none at start up , My car is catless stage 3 DME tune full Meistershaft exhaust
So I made a date to go to my Indy shop so they can diagnose the problem , it turns out to be a Turbo leaking oil into my exhaust side of the turbo, That was my guess also because the car is running great no check engine lights tons of power etc , Also just had a good oil report from Blackstone , by the time I got to the shop my car looked like a Hooptie with all that smoke billowing out it was getting worse by the minute , and man does that oil burning smell bad , I’m glad I didn’t get pulled over they would of probably had me tow it to the shop , Anyway my Indy shop new exactly what it was when I pulled up they said it’s very common for these turbos to do this on the S63tu , To be honest I was glad it was this and nothing worse , I had a Buick Grand National back in the day with the same problem. So instead of having the stock turbos rebuilt , There installing Stage 1 Pure turbos , after I know the engine is running fine it will be going back in for SSP SPEC R clutch pack in the near future So the shop is going to take some pics for me of the removal and comparison of the old turbos to the new , I will post them when I get them

Good luck. It will be exciting to get new turbos. When I was rebuilding my engine I thought about upgrading the turbos too but I was more than my budget would allow and also I didn't want to deal with emissions testing. Just curious but how do you guys deal with passing emissions. I look forward to your pictures and updates

@Whipple Very glad to hear it was nothing catastrophic. Looking forward to seeing the pictures. Subscribing to the thread.
@x-tech7 Brother the things I could have done project-wise but the cost of my wife's birthday dinner that night I lost engine, body damage from the shitty tow company and add to that just the nervousness of what to expect after rebuilding. Come to Florida if ya want to do away with the emissions testing problem

I am curious about the E85/93Octane mix. Do you have anything you can point me to that would give a good technical explanation?

Just an update where im at,Still waiting on the Turbos from Pure ,When I originally spoke my indy shop the impression was it was going to be only a week to week and a half , a day to order, two to three days to ship and 2 two days to install ,I spoke to pure turbos myself and they said its usually a 3-4 week lead time as they build them to order, I spoke to my indy again there telling me another week or 2,so my car has been siting around there for almost 3 weeks untouched ,I can't complain because the car was smoking so bad I couldn't drive it any more, its just one of those things.
The car isn't my daily so its not killing me but I do miss it big time

Just another update ,I got the car back with the new Turbos ,I drove it straight home due to a snow storm next day ,I finally got to drive it for awhile yesterday and believe it or not my problem with the smoke is still there,
The indy shop assumed it was the Turbos now im in a different boat ,they shouid have pulled my plugs and do a compression test and scope the cylinders , if thats good might be valve stem seals The power is stiil there and there is no noises coming from the engine, no check engine lights ,it seems to be running fine ,when it gets hot the smoke is really bad its undriveable ,going to bring it back to the shop in 2021 im done with 2020

Pull all your plugs and double check for any that are wet/smell of gasoline. This was my first symptom of a leaking fuel injector. Brought it to both BMW and atleast 2 indy shops all of whom couldn't identify an issue because I wasn't throwing any error codes. |

Hi guys I will end this thread here but the bad news is my motor is blown,I will be starting a new thread on the new build when the time comes,I believe I damaged a piston due to a faulty fuel injector ,The car still runs but spews oil smoke from the exhaust and I also hear a slight rod knock on load,All plans are decided for the rebuild I will share when I get data from the shop and we will see what exactly happened ,BTW No check engine lights, no drivetrain malfunction, I changed my oil every 2500 miles

Damn man, I am terribly sorry. Wasn't there a parts recall or TSB issued for the injectors? I know it may be an up hill battle with BMW but it might be worth considering. Wishing you much success with the rebuild.
On this same note; I wonder if running with a jb4 w/out a tune just to for log watching would have helped catch the injector issue. When I return home it is something i am going to look into.

Im not 100 percent sure if it was a failed injector until they take it apart it should be soon within the next 2 weeks ,thats was just my educated guess. Yes that is a very good combo to run < JB4 with a back end flash with JB4 controlling the Meth ,good thing about that is you can run and change several tunes on the fly, you can also datalog and send files to your tuner to make sure everything is running ok.and you can watch the gauges I will be doing this 100% on my build
