X5 diesal blue smoke

Hi

I have an X5 3litre diesal 2002.

A few weeks ago it started off with a slight miss and I was topping up the oil now and again. I then started to get blue smoke mainly at idle and low revs.
I took it into my garage and they said an injector was leaking into the chamber, so they changed it along with the turbo as the seal had gone.

Now it runs and drives perfect but still fills the road up with blue smoke and the oil still needs topping up.

Is it worth dong a compresion test on it, or could it be something else.

Pleas help!

J the boy

Hi , if you have had a turbo failure on this vehicle , just replacing the turbo will not cure the cause of blue smoke . depending how bad the seals had gone in the turbo you would need to replace , the complete exhaust system , the crankcase breater , air intake manifold , air charger but only if these items have been contaminated with oil , they would not be able to be cleaned out , hope this helps , regards mark

Maybe valve stem oil seals are getting worn allowing oil to enter the bore over a period of time , hence blue smoke on start up and miss fire on start up

My Ford Focus 2l tdci is smoking heavily by times. The car is for the past week in the workshop and no smoking occurred.How come blue smoke is pouring out of the exhaust only sometimes - then it is g


Hi Gert, If the smoke is more visible during the period after start up in the mornings, I would suspect the valve stem oil seals have become hardened and defective. The oil seeps in slowly passing the seals from the cylinder head. Sounds as though you need a head job. Regards John

My crystler concord just got an oil change 2 to 3 weeks ago and i changed the oil filter, but the oil level is already low, what does that mean?


Does the car emit blue smoke from the exhaust when driving? If so, either the piston rings or valve seals could be bad (expensive repair). The PCV valve could also be bad. The last reason (but no blue smoke) might be a physical oil leak due to a loose oil filter, drain plug, leaking oil pressure sensor, or worn crankshaft seal. Good luck!

CAMROD THROUGH ENGINE BLOCK 2 WEEKS AFTER CAMBELT REPLACED


The garage will say that they only re-built the head and will only warranty that part.
However they have a duty of care to check that their work covers all aspects of the work quoted for.

Note
Problem is that when a cam belt snaps it can drive two parts of the engine together (Valve and Piston Crown) which sometimes you get away with having a new Valve fitted and other times it puts a hole or a crack in the top of the piston.

This could explain your blue smoke as oil is being burnt off down the exhaust as oil is being drawn into the cylinder.

If the oil level gets too low pressure drops and you can get bearing failures which can lead to con rods snapping.

It is not normal for blue smoke to be emitted after a cylinder head rebuild !!

If blue smoke comes out of the exhaust there is oil being burnt off because of a mechanical problem.

If it is a professional garage they may come to an agreement with you , if it is a hole in the wall then your chances of redress are slim
