| OIL IN EXHAUST PIPES (LOTS OF BLUE SMOKE) LR3 V8 |
|
Hi
My LR3 V8 has oil from in its exhaust pipes while driving
When these are hot lots of blue smoke while driving
Engine runs on 8 cilinders
Motor management light is on
Sometimes it is gone for a day or two but it always returns
Does anyone has an idea
The engine has only 50.000 miles on the meter
Thanks a lot
Cheers

Reinder, welcome and apologies for the other misleading post.
Sounds like your engine is burning oil - are you regularly having to top up, and if so how much/often?

Winger thanks a lot for the welcome
After the smoking part oil has to be filled every time
It looks like it is poored from the engine directly into the exhaust pipes
With cold engine (and therefore cold exhaust pipes) you can actually see it driping down from both pipes
Tempature is stabel and not moving 1 mm (or inch)
I didn't drive my LR3 for 3 days now
I imported it from the USA last year
Could that be of any influence ??
For now my 23 year old def 90 must do all the work
Defenitly lots of smoke there!!!!!!!

Not really something to "internet diagnose", but something is clearly very wrong! I cannot see the import being a cause, just sounds like you've got a serious internal issue - piston rings, perhaps?

if it is something with the piston rings
can it be sometimes good and sometimes wrong
I mean can thy the function sometims well and a day later totally not?
and is it big money to replace them?
and one more question
can you find this problem when you connected my car to a computer/
tanks man
cheers

I'd think that if it is piston related, you'd not have "good" days.
If the engine fault light is coming on, then the engine ECU will be storing fault codes. Yes, if the car goes to a dealer equipped with the right diagnostic kit, they can read the fault codes that will assist with the diagnosis. It sounds like a LR dealer might be the place to start, unless you know a good independent - who will probably also be cheaper when it comes to fixing it.

I would check the PCV (positive crankshaft ventilation) valve. If it's defective, pressure buildup may push oil out the valve seals etc...

Does it happen immediately after you have topped the level up?
How much oil does it take to restore the correct level?

Okay, I haven't worked on engines in over 20 years, but seem to dimly recall that if the spark plugs are oily and fouled then the leak can be piston rings or valves. If the plugs look clean then it's something entering downstream of he cylinders, and probably less expensive to fix. As you said it's otherwise running smoothly, then the cylinders are probably not the source of the oil leek. Maybe pull all 8 spark plugs and have a look to confirm this, but I don't know if it takes an odd tool to do this on the V8 (I never even saw the spark plug on my D3 yet rebuilt piston aircraft engines in a much earlier life  ).
In either case, you really don't want to risk a fire from oil on the exhaust as I know from painful history that the beautiful alloy V8 can melt into a lump.

I would suggest a wet & dry compression test. More details on how to do it here:-

I vote check the crank breather. Run it down a long hill (if you have any) with no throttle on, floor it at the bottom of the hill if it smokes alot then its drawing oil down the valve seals.
But I would research the crank breather PCV option as the oil is intermittent. Club Pie n Pea

I don't know much about thie particular engine but...
If oil is running out ie getting into the bores in such quantities it can only be a few things ( i think )
either
1.a blockage allowing pressure to build up and blow oil past any seals...
2. a totally collapsed valve stem oil seal
3. a cracked block
4. a holed piston or shattered oil control ring
as I say I'm no expert on this lump and don't mind if you shoot me down

Hallo Reinder,
I don't know if your problem is solved already but if the MIL light is on there is a faultcode stored in the engine ECU and a dealer or independent can at least read the faultcode and probably have an idea of the problem. But oil in the exhaust sounds expensive and a lot off work.
You could try www.landroverspecialist.nl there labour prices are better then a LR dealer I know it's not close but they love Land Rovers.
