1. Turbo is passing quite a bit of oil - he took the clean air intake pipe off and ran it you can see the oil seeping past the turbine. There was some thrust movement in the shaft. I checked this a while ago and there wasn't any so it definitely has got worse.

2. Vacuum pump seal against the engine - MrSweet, you did mention this I know but I dismissed this as I had already changed all the seals. But once the mechanic pointed it out, it was obvious I hadn't sealed it properly. ALSO, at the time I changed the seals, I stupidly undid the head cover bolt just above the vac pump. I then couldn't tighten again which meant it must have sheared and I just left it. There is a possibility that this bolt also acts as a clamping force around the vac pump...hence again, not sealing properly. I did bring this up a while ago (https://www.e90post.com/forums/showthread.php?t=1508997) but never got round to sorting it as I didn't think it was an issue.

It's booked in with this same guy to fix the head cover bolt by removing the complete cover, replacing broken bolt and re-assembling and to properly fix the vac pump again. Once this is done, I'll replace turbo or have some company get mine rebuilt/refurbished etc.

I'm happy there is progress!

Ahh well if I replaced the seals mate I would have assumed the same, but Damn, if the bolt your talking about is the one I'm thinking about it's a Damn nightmare! I've came across a thread and the chap said he removed the two bolts above vacuum pump and it was a nightmare. I also have a some bookmarked M57n2 rebuild videos and again they take a blow torch to those same bolts as they must be prone to snapping but at least the chaps willing to do it for you.

I'm not sure where your from, but I take my BMW to BestTurbos based in Oldbury, they're specialists in BMW turbos and the guys there (Lucas and Martin) are awesome people. They'll take pictures and talk you through it all if your sceptical, they offer free diagnoses and 2 years warranty on parts and labour and of course as Rasa said this could be the perfect excuse for some Hybrids!

Glad your getting it sorted though mate, you don't have AA parts and garage cover do you? they put £500 towards any repairs and you can tell them where to drop it off as long as they're VAT registered, I got mine dropped to best turbo and cost me £220 after AA sent £500 cheque for a new turbo, seals, service, intercooler clean etc

Yep already discussing going hybrid with uprated intercooler and downpipe. Should be good! Always a positive to come out of a problem lol. Also, will def. install an LSD to make sure the power is put down well.

Yeah he was saying too that it is a big job! But yeah glad I ain't doing it lol.

Also, I am talking to ecotune in Glasgow. I've heard good things about them so lets see. I'm in Manchester but willing to make a long trip if needed! Nice one though.

Not got AA though...that would have been nice!

how did this go? did the hybrid turbo fix the smoking issue?

I have a constant blue smoke once warmed up with lots of oil from the breather pipe. the blue smoke eventually passes with lots of WOT or lots of fast revs, but comes back. I had the turbo replaced with a recon, and it's still there. Questioning the turbo.

I've done the VCG and replaced one injector that was showing inpa as 2.2 on WOT. still nothing.

Keen to know if this is all resolved?

[rasa bmw]

have you changed the breather and breather hose and gasket ?first thing id be doing as its not a waste of money or time as it needs doing sometime anyhow...and have you still got a dpf ?

Hi Rasa,

Think you're on my other thread too - yeah, breather changed, put a provent 200 in too, VCG done as per TIS

Turbo has been changed, but no difference.

Thinking it's either headgasket, rings are worn or valve seals.

[P14kle]

Next oil change use this..... https://rover.ebay.com/rover/0/0/0?m...2F350796977188

Has had great reviews on the whole. Worth a go if you think its worn rings or scored bores etc...

Know one person personally who said it cured his issues of excessive blow-by..

Sorry dude, not been on the forums for a while.

So yeah, I got the hybrid/new intercooler/custom downpipe/remap from Ecotune. so far, all good, no blue smoke.
In general car has been running very well aside a puff of white smoke at startup and then disappears.

I might be reviveing an old thread but a lot of people who seem to have the same problem are here so I wanted your opinions.
I am having the same problem, as in when i accelerate and the turbo goes in effect a massive black cloud appears from the exhaust, I investigated a bit more and there seems to be a leak from the small connector from the crankcase breather to the intake pipe to the turbo.
I changed the crankcase breather and noticed my crankcase breather is completly empty with no loo roll or vortex filter, should i buy one?

I was also suprised about the amount of oil that came out of the intercooler when i disconnected it.
I have a mapped car which has an output of 300hp and haven't checked the valve seals.

So i was now wondering is it the crankcase breather or the turbo leaking?
Is it the valve seals?
What worked out for you guys?

Different issue to you a bit mate, crankcase breather is oil related and if anything blue smoke. Black is partially/unburnt fuel which is fuel or air related. The crankcase breather is located at the back of the valve cover and as you've noticed contains no filter. The felt filter (loo roll) is better at filtering the oil out but be very careful because excess oil carried through will clog it in no time, the Vortex uses a Vortex of air so oil drops back and only have crankcase vapours pass through, for me this is what I prefer as I clogged a loo roll filter in about a month or two which was confirmed by the oil fill cap bouncing around. Changed to Vortex and the oil fill cap is perfect again.

The connector your referring to is the small 3 inch hose or so from the valve cover to the cold side intake? If so yes I'd imagine you'll have unburned fuel as the MAF located at the top of the cold side intake will log the correct amount of air only for you to lose some half way past the MAF. So fix that first, then check for turbo play, you should have slight movement up, down, left and right as we have a floating bearing and that play is taken up with oil pressure when the engine is started. If the compressor wheel touches the housing or moves in and out its gone.

Sorry for reviving the old thread, but I think I am having the same issue as you guys. I am getting a lot of oil on my (what seems to be) turbo outlet, which is then dripping onto the red intercooler hose and onto my driveway. I have attached some pictures as i just started noticing a leak. It also seems as though the right side of the outlet pipe isnt even bolted in like the one covered in oil which is probably giving me boost leaks. Bought it a week ago from a guy who supposedly took it to the dealer everytime an issue came up. Can this be the crank case breather?
