Oil leak from turbo TD4

It is only a few drops and there is no smoke. There is no leak from the hoses.
Is this something to be worried about?

Yes. Best investigate and see where the leak is. Mine, we think, sucked all the oil out through the turbo, resulting in a seized engine.

any oil leaking to the extent that it drips is a concern.

where exactly does it leak from?

has the engine breather filter been changed?

lift the dipstick with the engine running and check if oil rises up the dipstick tube.

Is this the same as "crankcase breather"? I ordered this from ebay for about a week a go.

yes it is.

did you lift the dipstick to test for excessive pressure?

No oil coming up from the dipstick. Not much pressure there at all....

OK forget crankcase pressure for the moment.
You'll have to clean the area of the leak and establish exactly where it's coming from. There is a oil feed pipe supplying engine oil under pressure and an oil return pipe to to the engine block that allows oil to drain back to the sump. The air inlet duct also gets oily inside from oil vapour from the engine breather system.

Hi I have this problem too saw some oil driping from the turbo unit.Mine has only done 90,000KMS. Does the turbo unit fail so quickly? I hope its just the oil feed pipe problem.

Does anyone have this problem before?Thanks.

Its a common problem,best thing ya can do is stick ya wopadoodle up the exhaust and light the catherine wheel pokein outta ya jacksie and wa hey we got us a porno film fer freelander lovers.

I think its the oil feed pipe connection as there would no way the turbo unit can leak oil outside its body.Correct me if i'm wrong.

Just came back from the dealership.They say its the breather that cause the leakage change them and will monitor from here.

Breather was my first thought. It vents into the hose/duct on the inlet of the turbo and could leak externally if the duct is not sealing properly on the turbo body.
There is also a oil drain pipe from the turbo to the block that could leak either from it's gasket or the hose connection.

Hi again.

I have not solved the problem yet, ( busy with work etc. ) but on norwegian LR forums they say that the catalysator is a big problems on modern common rail diesels. Because the cat gives to much resistance. This is not good for the turbo and the hoses around.

So, some of the guys with TD5 engine remove the cat and replace it with steel pipe. They say that the engine breath easier and get stronger up hills.

What about the MOT? Cat really dont help much on a diesel engine. But on a gasoline engine you must have it to clear the MOT.

I think I will remove mine soon.

Hi Chaser,

Is the duct part of the engine breather component?I change my engine oil very often 5,000kms and filter at 10,000kms.New turbo are very costly.Thanks

No, the duct I was referring to is the the one from the outlet of the Air filter housing to the inlet of the turbo.

The engine crankcase breather depression limiting valve (located in a housing on the camshaft cover) vents crankcase emissions into here after separating excess oil vapour.

I think the duct is ok.But what puzzles me is that my turbo unit is covered with oil how can by changing the breather solved the problem.Before changing the breather i checked the dipstick area and there is no pressure or oil leaking from there.

IF the depression limiting valve is faulty, ie. not limiting the amount of depression in the crankcase.

The inlet sucks the emissions from the crankcase if you like. If the valve doesn't close it sucks more than it is supposed to.

This is the opposite scenario to a blocked breather filter which prevents any crankcase depression, allowing pressure to build up instead, which is why oil can be pumped up the dipstick tube.

As for the oil all over the turbo, get an aerosol of degreaser and wash it off. Use a tray of some kind to catch the crap. When it's all clean run the engine and check for the source of the leak. Common sense really....

ok i saw the duct is not clip to the turbo body.Does it have clips?saw some oil sippind out from there than drip onto the IRD UNIT.

No it doesn't have a clip, it has a grommet/insert at each end to make a seal. You should remove the complete duct and check it and the grommet for damage. Pay particular attention to the small pipe that branches off as that is from the breather.
