Hey guys new here!!
Got a Defender td5 and she has started smoking on take off after idling at lights or extended crawling in 1st etc (Grey/Blue smoke)

Check out my youtube vid:
YouTube (https://youtu.be/fAS0sFbivaA)
YouTube (https://youtu.be/3vFlhWQxLHs)

Has done loads of k's 320k and is blowing fumes from oil filler.
Runs and starts well no loss of power, new turbo and chip tuned a couple of years ago.

Any help from anyone who has been down this road would be appreciated.

Hey fellow Landy Lovers,
My bad Smokey1 was my second account, i thought my first account wasn't working and started a new one.
Well mods notified me and i have now reactivated my old account.
I'm really concerned about my girl (see above)
Does anyone have any ideas, would i be able to tell if valve seals or injectors are faulty by removing crank case for inspections?

I think you might not want to hear the truth [bighmmm]

Fuming is not good and the blue smoke out the back is not good either in my opinion it points to terminal :wallbash:

Has the motor been dusted at all ? does it use oil ?

Might be time for a compression check which might answer some of your questions i think :BigCry:

The smoke appears to have quite a black component but looking from behind or above would give a clearer picture.

How many kms since the last oil change and was the correct oil used?

Remembering from my younger days, blue smoke from an overhead valve engine after lots of idling usually indicated that oil was getting past the valve stem seals, either because the seals had gone hard or the guides too badly worn or both.

How long since the inter-cooler was cleaned?

Hey Guys,
Thanks for the replies.
What does dusting down the engine mean?
She had used about 2ltrs of oil in the last 10000ks, was previously running penrite 5w40 but chucked in some 15w40 to see if would make a difference.
Removed and flushed intercooler a month ago when i installed catch can, cleaned MAF and temp sensors.
There was oil dripping back out of inlet manifold when i removed intake pipe.
Still pulls like a train, could it be injectors?

'Dusting' is when you have bypass around the air cleaner, e.g. a poorly sealed element, hose lose upstream, etc. and the engine ingests unfiltered air and rings and bore suffer serious wear.

It doesn't take much to kill an engine, sometimes only 1/2-1 hour run time and the engine is toast.

FWIW air filtration is far more important than the oil filter for long, reliable engine life.

BTW a 15w-40 oil will make no difference in consumption compared to a 5w-40, they are the same viscosity at normal operating temps and for that matter most temps above 0°

Over-fuelling wont cause oil consumption but leaking injector seals will allow the oil to be diluted and vaporised more readily producing excessive crankcase gasses, although a rising oil level is the usual visible indication. Using 2L in 10K is a lot. Are steel head locating dowels fitted? If not then the head may have walked although compression usually gets into the coolant when this happens.

Thanks again for the replies.
Have been going over receipts from previous owner on previous work done.
There was a charge for cylinder head reco back in 2014 for $670 + $593 for bolt kit and gasket set.
Does that price seem right?
(apparently the bores looked like new so they didn't touch the bottom end)

If they didn't replace the locators with metal ones is there a way to visually check if the head has walked without removing the head?

It just doesn't make sense that its blowing so much smoke after idling and not up hills or under heavy load (other than the usual from a 330k tuned engine;) ) which makes me think its not the rings.

Anyway contemplating just pulling the head off to have a look...

Moved heads sometimes result in valves rubbing on bores. Mine's head had moved 2-3mm sideways judging by the shape of the dowels but no bore damage, with compression into the coolant the trigger for the head removal and found to have been leaking close to the front of the head.

Note that LR state that the steel dowels fitted to later engines are unsuitable for replacing the earlier plastic dowels because they risk cracking the head. I assumed that the steel dowels were longer but wasn't able to confirm so used sections of the shank of an 8mm drill bit which fitted snugly. If the 2014 head work followed LR's advice then plastic dowels would have been used. However I'm more inclined to suspect valve stem seals as the culprit especially if the smoke is worst after idling.

However I'm more inclined to suspect valve stem seals as the culprit especially if the smoke is worst after idling.

The reason that petrol engines smoke after idling is that at idle there is a high vacuum in the inlet manifold so oil is pulled down into the combustion chamber via the inlet valve. This does not apply so much to a diesel.

I would also suspect a dying turbo with oil being passed into the inlet manifold and into the intercooler , then being sucked in with increased air flow.
The blow by would also feed oil into the manifold via the depression valve.

My guess is a combination of things called "old engine' , that needs a refresh. Maybe including bottom end.

Took another video on the way home....
This was punching it up hill till 100kh under full load:

And this was take off at the next lights:

Ps is that too much black smoke for a tuned TD5? I expect to have a bit.

Fyi turbo was replaced with brand new garrett in 2016.

Something obviously isn’t right not sure what though.
Almost looks like rings maybe broken rings?
Are the intercooler hoses excessively oily? this would support Phillips suggestion re turbo
Can the catch can create an issue like this?
Seen plenty of td5s make more black smoke than that provided it is pre boost I figure it’s ok
What are the EGTs

Sorry have no diagnostic tool or egt temp gauge.
I had cleaned out the intercooler a month ago there wasn't an excessive amount of oil in there i think most of it is coming through the breather hose.

So what was the outcome?

Hi Smokey1,
I have had a Smokey td5 for a while and a fuel starvation issue where the car would stall randomly. I would get a whoosh when removing the fuel cap, my mechanic suggested this was wrong so I have tried driving around with the fuel cap just sitting in place by a few threads. And bingo Smokeyness gone and so has the stalling.
I now need to get myself a properly vented cap.
Give it a crack.
