I saw it start last week. Can only see it at night when getting on the freeway at full throtle with a car behind me (see it thru the headlights). I watched it durring the day and can't see anything.
I bought it a year ago w/ 35k and have 53k on it right now. Treat it like my baby, everything done when supposed to. I don't have any reason to suspect anything, other than the smoke that is.
Here's why I'm really confused:
I'm a Land Rover Sales Guide, so I drive these things all day / every day. Mine is by far the nicest DI (98 LE) I've seen on our lot. It has more power, better handling and less noises than any other DI I've ever seen. I haven't been able to pry the keys out of my wifes hands to get it in the shop yet, but this did only show up last week.
Ideas?
Sugestions?
Comments?
Back-woods-red-neck-theories?

Are you sure that you didn't just blow the carbon out of it. mine will do that once and a while. Alot of slow city driving for me |

I had an oil pressure sensor go on me - started with a gradual smoking at speed (I noticed it at night in rear-view mirror due to headlights as well.
The sensor went entirely a couple of days later, spraying engine oil all over the lower parts of the bay. At speed, the oil hit the manifold creating all the smoke.
Have the thing checked along with your seals - you may not have a drop of oil under the car when it isn't running! Because of this, I had almost ruled out a leak altogether.
In my case the part cost me about $36 and I had a friend help with the install. Very simple - hopefully you may have the same luck!

LOL
To put it succintly, when you floor it, you burn a lot of gas. This produces a lot of smoke (at least a pretty noticable amount).
Tell me you've never seen other cars do it. No, it is not an oil leak (which produces noticable blue smoke all the time, and not just under heavy acceleration), a blown sensor gasket, or the indication of a valvetrain about to stick. At the most, it's like MTB said about you "blowing the carbon out," since if you've never noticed your truck do it at full throttle, or any other cars blow a little smoke when they floored it, then you've probably got a lot of carbon to blow out. It's healthy. |

i like to use to term "flogging".
"good to give it a flogging once in a while!!"

how are you defining "it", GP? |

flogging can be used in a variety of ways. not just in terms of trucks or cars, but with people as well. but i really don't need to get into that on this board. i was just using it in reference to my truck........"taking it out and giving it a good flogging".....meaning driving it hard and keeping the revs up there for a little bit. no....was not talking about something else you may have been thinking about. i mean what kind of person do you think i am!!

I keep hearing "blow the carbon out", but I must say I'm not entirely familiar w/ this. I know the theories, but have never seen most of it.
When we were under the covers last month our lead mech saw some buildup on the lifters, he said it was not even worth mentioning to most people but because of my service history and the fact that I work with him every day he did.
Could this be the 'carbon' everyone is talking about? If so what is the fix (other than a rebuild)?
My other major concern is that I want to sell this car private party after I get my 03 Disco (already on order, YIPPY!), and I'm really not intersted in dumping a problem on someone else. |

That comes from times of old, when engines were carburetted, after they stopped burning leaded gas Over time, moderate, short-distance driving lead to carbon build-up in the venturi of the carburettors (as well as on the valve seats)and could cause rough running (if severe enough) and lack of performance, and the easiest way to get the build-up out was to drive the engine hard from time-to-time and "blow the carbon out," which would keep the carb and valves mostly clean.
Engines in newer vehicles of all makes can suffer from carbon fouling (obviously carburettors aren't an issue anymore) usually on the valve seats, spark plugs, and sometimes at the fuel injector nozzles. People who drive their vehicles ultra-conservatively experience it more often than anybody else, but it's usually easily cured with fuel additives and regular "spirited" driving |

So my gentel driving style is actually damning the car? That's ironic, ha ha. I'll go out tonight and give her a good flogging...
Ok, so additives huh? Any sugestions on a brand? Wouldn't there be fear of the additive breaking apart the carbon and cloging the rest of the system? Or is this not an issue? |

i have used a variety of things to get my check engine light to go off and finally did. not sure which product did it, but i used some BG44K about 3 weeks ago. pricey at around $20 for a small can, but supposidly good stuff. used some MOA on my last oil change too. and then i used some cleaner from Amsoil that you spray into the intake while the truck is running. yeah......i got a little carried away i think. but hey the light went off from my engine misfire codes!!! now i just have to put some tape over that ABS light. all this + i drive it pretty hard every other day, since it is such a sporty and spirited truck. haha. |

I wouldn't worry about carbon breaking up and clogging anything. If anything it'll get blown out the exhaust, so at the most you'd notice more black soot around the tip of your exhaust pipe while everything's getting cleaned-out. That BG44K stuff Garrett mentioned is about the best I've heard of for cleaning carbon fouling. A good practice (if you'd prefer to maintain your smooth driving style) is to add a can of that stuff to your gas at about the same frequency as you have oil changes. I should think any more often than that would be wasteful, but I'm sure the can says otherwise |
