My check engine light recently came on in my 2000 disco w/ 36k. Dealer told me several cylinders were misfiring and it needed a valve job. Luckily, covered by warranty. However, it was just two to three burned out spark plugs. I have no idea how they were burned out. Replaced them and it seemed to do the trick. I will have them check again before it hits 50k |

They told me the same thing on my Disco and it was the coil. Bastards.

Well guys, I'm sure there is some truth to the dealer churning warranty work but the real truth is that by design ALL discoverys from 1996-2002 will at some point need a valve job. The reason, is poor design by those british bozos. The exaust valves are machined too close in tolerance to the exaust valve guide. Once you get any carbon build up on the valve, which you will, the valve will momentarly seize causing a misfire. the light comes on showing the misfire code. the fix recommended by LRNA is to clean carbon off valves and ream out the exaust guides with their special tool reamer. Why do they not fix this? The rest of the world doesn't have the strict emmissions laws so the ecu's don't have to turn the light near as often. As a former L/R tech, I can tell you that 90% of the time you won't even notice the engine running any different. The ecu will turn on the light if only a couple of misfires are detected. If you are told by your dealer that your car needs a valve job and its out of warranty and runs fine, tell them to reset light, if they will and keep driving. yes, there is some danger that the valve will eventually stick completly and bend but this is rare. Take your car out on the highway and blow it out. BG makes a treatment called 44K that will help alot. Rover is just recently decided to use there own fuel treatment at every service interval to prevent this condition. We have been telling them for years that this will help but the british are too close minded to listen. Now , they finially believe us. I hope this helps .
Cheers

Does this value job have to do with the ticking i am hearing while at a red light or is that something else? 2000 D2 |

does anyone know where you can buy BG 44k. I would like to start using it as a preventative measure. Joe, whats your suggestion as to the frequency of use.
thanks, John |

Joe,
From what your saying "ALL discoverys from 1996-2002 will at some point need a valve job." I should have the valves done BEFORE my warranty runs out never mind that they are fine now. Everyone needs a good reaming now and again.
Pete,
You may be listening to your rockers chattering to each other...another common problem. Mine were rebuilt at @ 15k. |

by "blowing it out "
not sure if this helps but I frequently leave my DII in 3rd on the highway and get those RPMs up to about 3.5 - for several minutes and then shift back to 4th - opinions??
what else besides BGK44 would work? That stuff is not that common - down south
I did hear from another Land Rover mechanic that they all need valve jobs eventually.
What the hell can we tell the dealers to get them to warranty the work so we don't have to pay for this BS ourselves? |

I've had good luck with Lubro Moly Ventil Sauber. It's available everywhere. Try www.gprparts.com and look it up under maintenace products. |

Is this the reason they 'require' that we use the highest octane gas? |
GregH

No. Higher compression, or in the case of older LR's with low comp., advanced timing is what requires higher octane. |

Is the BGK44 similiar to the decarboning chemicals
like stp gas treatment?
Thanks

My 2000 Discovery (38K miles) had rockers replaced under warranty two weeks ago. Yes, the ticking at idle was getting louder. When I signed off on the paper work, I looked at the second page to get an idea of repair cost out of warranty. The charge back to LRNA...$450.00!
Strange, the "Service Engine Soon" light came on 500 miles after leaving the dealership...and the ticking noise at idle is now back, and getting stronger. Time for another trip back to the Dealer. |

I think any treatment thatif sake for fuel injection and will de-carbon engine will help alot. If you see a decarboning treatment by berrymen or stp it should help.
As far as rckers go, Its very hard to figure out what side of motor the noise is comming from. LRNA won't let us do all at once. I guess they would rather you come back for a second visit or give up about the problem. Its the british thing, typical rover stuff.

I have a 1998 that had to have a valve job. Exhaust valve bent the other cracked. My tech stated that this is very common. I think that this should be a recall by LR. |

The real problem is a faulty program in the ECU. This problem only exists in certain model years in the North American market. The only real fix is to get the ECU reprogramed. The valve job is only a temporary fix, or masking the real problem, which is a faulty fueling map.
There are also agrivating factors which can make the problem even worse. Ex:
Not using premium fuel
Driving habits
Local climates and fuel formulas
