Im in desperate need of help fixing my car, in the middle of a pull there I had a misfire which wasn't too uncommon for me so I limped the car home (I was a few blocks away). When I got home I realized I was pouring out white smoke and reeked of oil. Trying to find out whats wrong right now and what I should do. I pulled the spark plugs and cylinders 2,3,4 were covered in oil. There is also oil dripping from the v-band clamp where it meets the down-pipe. I removed one of the inter-cooler lines and saw a little oil but it seems like normal blow-by, I might take out the whole inter cooler and see whats going on inside it. The car pours white smoke the moment its turned on even when cold. I am also going to do a compression test and look in the cylinders with a borescope in a bit. Please help me out if anyone has an Idea of what is going on. Links on bottom are pics of the spark plug and the turbo that is leaking, sorry about the vertical video

What are the DME codes?

I'd say your turbos are blown, or at least one of them. The only way you'll be able to tell if your engine block is ok is with that compression test but it really looks like your turbos are blown.

Thanks for the help everyone, I really appreciate it. I just ran a compression test and the results are sad

cylinder 1: 160
cylinder 2: 160
cylinder 3: 160
cylinder 4: 0
cylinder 5: 160
cylinder 6: 155

Currently weighing out my options. Buying a donor car and use that N54 would also do a manual swap and Idrive conversion if i go that route to get the car I always wanted, or option 2 is parting out my baby and buying and rebuilding an f80. Im in the middle of midterms but I work for a Mercedes dealership that has graciously lent me a loaner s class until I fix my car. What do you guys think?

Dude all that smoke makes your car look like a chimney. Looks like a blown turbo or a head gasket/ engine failure

Edit: just saw your compression. That sucks, did you have any mods or pre existing issues? It's highly unlikely for an engine to just go to shit after a pull

I know -__-, as for mods its just about FBO minus meth; mhd e60 flash, upgraded walbro 450 lpfp, dci, downpipes, secondary cat delete, tial box and vrsf chargepipe, arm stepped intercooler.

No prexisting issues, I did so much preventative maintenance on the engine, injectors coils and spark plugs all had less than 15k on them, oil changes every 5k with bmw oil, changed transmission fluid and filters twice, flushed rear diff, regular coolant changes. I really took as best care for it as I could.

The DME only has codes for misfire in cylinder 4 and the exhaust flap (golf tee mod)

Driving with misfires is a big no-no, especially for FI cars.

Yes I don't normally drive around misfiring, what i should have said to be clearer is saying I have dealt with misfires before when I tuned it so that why I changed all the plugs coils and injectors. Driving it home wasn't the best idea however I was 2 streets away from home and didn't think it was going to be this big of a problem. (bad assumption)

[galahad05]

Yeah Sorry to hear that man. That cylinder 4 compression reading is serious bad news.
Cylinder rings, head gasket, valves. One of those....

[weehe126]

To get that low of a compression result I'd expect a hole in the piston.

You can pull #4 plug and look inside with a camera or pull intake and look that way also. Maybe its a valve. Good luck.

PSI cylinder 4 ? Death Sentence. Probably your head valve seals/stems..

thats why you are misfiring. no compression.

[ThugzZ BunnY]

its not going to be just one thing. you messed up big time. how much boost do you run?

Its MHD e60, I believe its targeting 18-19 psi. Im trying to figure out whats going on.

I looked at the top of the piston and it looks fine, I'm going to try a leak down test this afternoon, I'm still not 100 percent sure whats going on. When I pulled off the charge pipe from the intake manifold about 8 ounces of poured out?!

Ill be running a leak down test today, Progress has been slow because of midterms but i will be really going at it soon! Will post results of what I find

Very cool man thanks for updating. Sucks this has happened but you will learn more and maybe even have a better engine at the end of all this.

Keep us updated very interested. We can provide as much advise as possible

Well well well...Rusnak eh? You know Trish?

[08TUNDRA]

Well, did a leak down test today and confirmed that that there is 100% leak down in cyl. 4 I hear it all through the oil cap so I'm assuming its rings, I used a bore scope camera and the top of the piston looks fine visually. Beginning my tear down looking at buying a totaled e92 to serve as a donor car hopefully I can get my baby back and running soon. Just curious now as to what happened because I would like to prevent it from happening again.

Hahahah TBH my family has bought 4 BMW's from them and we all still have the dealer plates on, mine being the oldest of our cars wasn't even bought there, The cops in my area don't really care about licence plates.
