Black smoke

I'm getting black smoke and oil's spewing outta the exhaust..
help...

If that's a petrol V8 ....


Far too much petrol going in ....

could be AIR FILTER blocked with water or OIL from Breathers.

Stage one - take the air filter element out and see if that helps. Have a look at the filter while it is out. It is quite interesting really ...

could be the breathers that are blocked! try running the engine then while it is running just undo the oil filler cap and see if it releases the pressure. if it does then the breathers are blocked.

Had any nice sand storms out there lately? Sand blocks up EVERYTHING!

haha.. yeah we've had a couple bad sand storms recently.. probably.. my oil indicator doesn't work..so i'm guessing it is time to do the oil change..i'm gonna do a check anyway and if so how do i unblock the breathers??

and ever since the expulsion of smoke.. the mileage has decreased drastically.. getting 200 km for a full tank ( 15 US gallons)

Errmm Discos have an 80ltr (20 us gallons) tank. So it's even worst than you thought.

ahhhhhhhhhhh.. i keep filling it up before the it touches the reserves... what could be it??

as has been said earlier Black smoke is caused by running too rich. so air starvation sounds likeliest

THROW AWAY THE CLOGGED AIR FILTER!

Fit a new one.

But NEVER run without one out there. the sand will eat your engine. I've known people out inthe desert change their air filter every two weeks, they clog up so quickly. That's one reason LR used to fit oil bath filters, that can be cleaned out regularly.

reckon a K&N filter would be good enough??

Sorry, my knowledge doesn't extend that far. Basically, a filter is a matrix of fine holes to let air through but trap gunge. The sand will block the holes and you need to change the filter. Might be worth investigating to see if there is a washable filter available. First thing to do is to change it and see if it cures the problem! Any cheap filter will do at this stage.

especially in sharjah.. i keep slapping the filter around objects to dust it off.. guess it was not that useful..and one more thing.. could the spark plugs be another issue??

mechanics ae saying could be the fuel injector, Air mass flow meter, 1 or 2 cylinders not working...arrrghhh

Did you put a NEW air filter element in? If so and no improvement, the mechanics are probably right. The other thing which often causes black smoke is degraded HT leads. They tend to go and need replacing after about 40000 miles. But it wouldn't happen suddenly.

no..i did not get the air filter changed.. and some times the engine misfires....this car is ****ed..

Can't see why you asked for our advice if you didn't take it. CharlesY knows more about landrovers than anyone else on the planet. Changing the air filter is such an obvious starting point, and takes a few seconds. Your "mechanics" may be right, but I wouldn't take their expensive advice without checking the obvious first.

Whoa there Pastmaster!
I think you are way out of line there!

My knowledge of petrol engines and diesels comes from a lifetime of having to do it myself, if only to get it done right, and to know that it has been done at all! The last time I put a car into a garage was my brand new MiniVan FHS 880 C at 1,000 miles for it's "free" first service, which of course I had just paid for when I bought the van. £360 it was ... my life's savings. I captured them in January 1966 for doing NOTHING to the van - no re-torque of the head, no check of valve cleances, no adjust of the brakes, but worst of all no oil change and no new filter. I challenged them, and they just laughed in my face. I reported them to BMC, who didn't give a ****.

It was about then I started buying tools, books, and learning how to do it all myself. It had occurred to me that is people THAT stupid could run a garage, it can't be impossible for me to look after a Minivan.

Now I reckon to have enough tools here to do just about anything, and if I need an even bigger hammer I know someone along the road who has a beezer. In fact I can hardly get in my shed for "stuff".

My skills lie in the diagnosis, the theory, analysis, together with a good experience of Landies over the years, but there are probably scores of guys on this llst with a lot more hard practical experience than I have, and they are great people to watch in action. I could do with a couple of them up here to do a Disco chassis swap and body job for me - a 200 tdi project. A team of them could come up here, live in a caravan, and do the job! For MONEY ......

Great forum. I hope you guys can put up with me a while longer.
