black smoke from down buy the turbo and out the back

hi all am new on here so go easy. am not to shore if she a freelander 1 or 2

i have a freelander td4 51 plate the car has been of the road for 12 months because of the problems with it and with me working in new job i never had the time until now .. the problems with the freelander were black smoke out the exhaust and also smoke from down buy the turbo area.

this is what i have done so far
i have took of the EGR valve cleaned it out full of oil etc
i have checked all the pipes for splits or holes/ only pipes i have not checked is ones that go on to the turbo.

am thinking with the smoke coming from down buy the turbo maybe a pipe has split or come lose but am struggling to gain excess to the turbo area so if anyone could be kind enough to help me with advice to maybe the course of the problems or what pipes clip on to the turbo that might of damaged.

my grandad gave me the car a few years ago and has since passed away so be grate get her running again.

thank you for your time.

You have a freelander 1

The turbo feeds into the EGR by way of a 'flexible' metal pipe, its flexibility is due to a similar action as a tumble dryer duct . This can crack and release fumes, but will sound a bit louder under use. If you have taken the EGR off you may well have cracked this pipe that feeds the Exhaust gas to it.

You need to be under the car looking up at the back of the engine. The turbo is on the drivers side and feeds via the flexible pipe around the back of the engine to the EGR on the left.

thank you skynet
the car was smoking before i took of the EGR valve. you can see the smoke coming from the back of the engine on the drivers side. i have been told the turbo has gone but am not to shore cos point me out if am wrong but arnt diesel engines water tight unless you get it in the filter cos if so the whey am thinking is if smoke is coming out from down buy the turbo then water can get in meaning there has to be a pipe split or something. i do apologize buy the way i just explained all this but its only way i can.

You are going to have to get under it and have a look.

If it is normal exhaust smoke from that area, either the EGR pipe is the problem as mentioned above or the exhaust downpipe has come undone from the turbo. Even with it completely disconnected, engine noise is not drastically louder, so a small leak will sound no different, but allow exhaust gas to escape.

Otherwise....oil from the turbos lubrication system could be leaking, either from the high pressure feed pipe or the return pipe and the oil is burning off when the engine is hot, making the smoke.

Access is very, very tight from underneath - you will need the undertray off and on your back under the car looking up behind the engine, the turbo is only just visible above the IRD. The nuts securing the exhaust down pipe are a pain - on is accessible from underneath with a normal spanner, the other needs to be accessed from the left hand wheel arch with about 2 feet of extensions to get a socket onto the nut. With the air filter box removed, it is possible to get your hands to it from above and you can see stuff with a torch and a small mirror.

As you've got to get under the car, if you know anyone with an inspection pit and you can get the car there - I'd recommend you do it. Makes life a lot easier.

You have changed the crank case filter since you've had it I assume?

i haven't changed the crank case filter i have had it off and its full of sticky oil i thought ill do all them and service once i find the course of the black smoke leaking from buy turbo and out the back. am not to shore if it is but on top the engine there is a manifold think its that and the EGR valve connects to it well when i had the EGR valve off there is a load of sticky oil in what i think is the manifold and also there is oil everywhere in the engine bay sponge on the hood etc. can anyone say if my turbo has gone from all the symptoms i have said in my posts. cos i don't really want to spend money on service parts if my turbo has gone or something else major i appreciate all your help guys and i do apologis for my lack of mechanical knowledge but ill be under it tomorrow and have a look at all the pipes and get back to you and thanks again guys.

1 - Try some of these.... . , ; sprinkle them at random through your text, some might land in the right places.


2 - See everything I wrote a few posts further up? Yeah, that was on the assumption that your car is basically ok mechanical condition, you have checked the basics and you carry out routine necessary maintenance before asking for help on the internet.
Obviously I was wrong, and I make a full and frank apology to you for not checking my crystal ball before posting.
Oil everywhere? clogged crank case filter? manky EGR? whats worse is that you KNOW the crank case filter is clogged, so you obviously removed it, had a look, then decided to put it back?

Fix that ****. Service it. Properly. Clean off excess spilled oil, THEN start looking for other problems.

+1

I'll take that +1 and raise it to +20.

Sort the crank case breather filter first as you are pressurising you're crankcase all the time it's clogged...

You can get the newer cyclone type off ebay, I bought this one: CYLINDER HEAD BREATHER KIT E46,E90,E60 M47N 03- BMW 1 SERIES (E87) 04-11 HATCHBA | eBay

Not the cheapest but on close inspection after researching I am certain it is OE spec, if not OE supplier. Then see if you still have smoke leaking anywhere. I wouldn't be surprised if the pressure was forcing oil onto the hot exhaust and burning off.

do what 'spacemonkey' said ..

as it's most likely the cause of your problem

this .pdf explains why:

~~~~~~~~~~~~~~~~

and the engine will be better off by getting rid of the egr valve .. substitute an 'egr delete' unit for it ..
one less thing to go wrong ..

like i said my mechanical knowledge is not good ill change all the filters etc and Service it. i just thought there was another problem so i was going to fix that then if all was well service it but as you said ill service it 1st then move on from there. is the crank case filter buy the injectors a black lid you undo is that rite one...and dave21478 am sorry for my dave21478 i have dyslexia i try my best. but still thank you for your time with the help.

Have a read here:

ROVER 75 MGZT SERVICING

The breather is the PCV thing right at the bottom, but read it all.

And here:

ROVER 75 MGZT ENGINE FAULT FINDING


That should be enough to get you worried for now..!!

But seriously, get rid of the PCV breather and fit the newer BMW cyclone type unit I linked to on ebay before panicking too much.

just had a quick look throw, the bit about the OIL PUMPS OUT OF THE DIPSTICK AND EXHAUST SMOKE IS BLUE. but dose also say on the other link it can be black witch i have the same problems. if the pvc is blocked etc how can it produce smoke from coming out from somewhere buy the turbo or with it being blocked and the pressor have coursed it to pop off a pipe or split one. but thank you for the link spacemonkey its a grate help and very much what i have with problems with mine.

If PVC is blocked it stops the flow and creates back pressure in the system. This forces oil out of dipstick hole and can split hoses.

That's right- basically the engine pressurises itself and blows fumes and oil out of it's seals. Sort the PCV NOW as it sounds like it's doing that already. If it goes on too long the seals could suffer permanent damage - if they haven't already.

hi guys thanks again is it just the filter i need? or the hole unit. cos i carnt get my head around a little filter that might be giving me all these problem, ill be getting the part tomorrow so just want check.

If you just change the filter (or wash the old one out with solvents) it will clog up again in no time. If you just buy the unit in the ebay link I gave, it replaces the whole thing and you shouldn't have to worry about it again. The engine creates pressure inside and this valve is the pressure release valve. If you don;t let it out of the controlled valve, guess what will happen? Oil will **** out everywhere which can cause black smoke... Get it yet?

Change it before this happens:

Yes i get it penny dropped. I have been reading up some people have put a new pvc on all plastic with no filter init. Just wondering if this would be better option cos no filter to clog up or shall i stick to that link any inlight on this new plastic one.

hello
hi i am on that eBay link you gave me, but there is a list of other BMW models etc and am not to shore witch on i need to purchase for my 51 plate td4. if anyone could help me out with part number be grate thanks.
