Hello ,i have bitten the bullet again and last week i part exchanged my old discovery in against a td4 freelander 05 plate se model with 73000 on the clock. Three owners but it looks as if its been well looked after.
I owned an earlier model several years back and it was nothing but trouble ,but i thought id give it a try again with a newer model.
Ayway i bought it from a local garage with a good reputation and 3 months warranty. When i first had a test run ,it had been stood for quite a long while and quite a lot of blue smoke was emited from the exhaust.
The mechanic said it was because it had been stood for several weeks.
Anyway it soon cleared and was fine.
Long story short i bought the vehicle and haveonly put 60 miles on it after purchasing from the garage.
When i start up im getting blue smoke from the exhaust. It clears as soon as its emitted it runs smoothly on the road and no sighn of smoke if i rev it up.
If i leave it parked up for 3 or 4 hours and start up again im getting blue smoke again. Im taking it back to the garage in next cpl of days but it would be helpfull if i had some sort of info on what could be causing this.
I thank you for any help or tips you may have for me.
Regards.
 
Hi , could be a few things , overfueling causes black smoke the maf could be out of spec , has the crankcase breather filter been changed , also the air filter theres plenty of info on here , so have a read :)
 
Thanks ian,im going to take it back to garage in next cpl of days .Ill check on the breather you mention. Iknow the guy said it has just had a service. Ill check if they did the filters.
 
Hi, Blue smoke would indicate to me oil burning from cold, Could be valve stem seals allowing a little oil to seep into the cylinders when parked up but as mentioned above it could be a blocked breather but thought that would smoke more when warmed up? make sure they sort it when you take it back. Good luck.
 
Hi Mullet,

Does it look like this when you start up:

P1100224.JPG

This was the beginning. Light blue smoke on start up. I didn't take care of it because there where no other problems and the smoke was gone after a few meters.

Then after a while, it wouldn't start when the enigine was warm. Then after a while, the car shook a little when iddle.

I took it to a Bosch Diesel Service. They checked the injectors. 3 where gone and one was hard on it's way. Also my Bosch HP fuel pump was leaking and we put four new glowplugs in.

Problems are gone.

Maybe you have to check your injectors to.

Silkwood,thanks for your help along with the picture.I would say that when i start up the smoke is a lot more blu,er than in your photograph. But the weather or the light contrast when the photo was taken could be different.All the same its decent of you to post a picture,many thanks.A couple of days back when i started it took a few more seconds to fire and i thought then why the delay. But it does seem to run well and seems clean when on a run.As i havend done any miles in it yet i cant really tell if its burning oil or not either.The more i keep searching also on this im getting lots of other drivers with simillar problems ,not just this site but others. Thanks again guys for your help.
 
mine has always done it, have changed all filters, maf etc and its still doing it!! doesn't use a drop of oil so i'm picking up new injectors one by one and will change them once i've got a full set!

as you will probably read, injectors are pretty much classed as a 'service item' any time after 75k

Hi , again as a rule the crankcase filter gets neglected in a service , but as mentioned it could be injector related , good luck

Sounds like you need new valve stem oil seals and/or new valve guides (in most cases just the seals). Usually blue smoke emission will be a little worse if you have the engine warmed-up and you rev it after allowing a 10 minute idle.

Nothing fatal and the engine will run on for many more miles to come, regardless. Uness it fails its MOT, of course.
 
i spoke to landrover about this today because mine does it they say it is not a proble it just the egr valve when you press the go pedel it closes and when you take your foot of it open its all to do with reciculating exhaust gasses so nothing to worry about unless it does it all the time
 
Hi again and thanks for all the information on this.
This is an update. Yesterday i took vehicle back to the garage and had a chat to the mechaninc and he explained that the service had been done last week and the air filter changed. also He said it was very unlikley to be guide seals.
He said sometimes an injector can drip when not running and this could be a possible cause.He also told me that when they start up their L/Rs almost every day just to keep batteries charged,That it is common for them to smoke a little.
He replaced the crancase breather while i waited and when it fired up it was not showing any sighns of smoke.
I left it overnight and first thing this morning i started it up and just a slight showing of bluish smoke and then in a couple of seconds it cleared.
It is now looking as if it was the cranckase breather, But only time will tell.
If it does return next step is propably injector testing .I hope this may be of some interest to someone.
Thanks again.

BMW have modified the crankcase breather for the M47 td4 engine , in place of the filter is a vortex oil separator which should not clog , do a search on here also can recomend a EGR bypass mod , see the sticky by ming :)
 
Hi,my 04 td4 was ok till i changed the crankcase breather filter,now it emits blue smoke and lumpy running on start up for a few seconds then clears,what could i have done to cause this?
 
it could also be the heater plugs are failing a bit I am going to change mine before next winter as when it was really cold I switched ignition on then off and strait back on again , the glow plugs had a double warm up and less smoke came out for what they cost that's a job I am going to do.
