Dear Disco owners,
I have posted a few queries on discoweb regarding a nagging question as to why my engine knocks (a DII with 57,000 kilometers). The dealer kept on telling me it was piston resonance, and that it was a normal sound. So on Saturday, I took it to an independent mechanic. He did a compression check, and here are the results.
Cylinders 1, 2, 3, 4, 5, and 7 are at 180. Cylinder 6 is at 120, and cylinder 8 is at 150.
So, I am now going to the dealership, with this information, and am going to ask that they fix the problem.
I would be grateful for any advice from anyone, so that when i go to the dealership, I am fully prepared with credible information that they cannot question, so I can finally get them to fix the probelm, rather than hear their story that this is normal.
Many thanks in advance,
Arman. |

Get a leakdown test so that you can tell where you are losing the compression. May be valves not closing fully, piston rings, gasket issues, etc. That will be your needed evidence.

PerroneFord,
Thank you for the input. Is a leakdown test a time consuming and expensive test, or is it similar in cost and time to a compression test? |

6 and 8 are right next to each other. You likely have a head gasket that is getting a little bit of a leak or maybe a warped head. In any case the dealer should fix it irregardless of the problem. Don't bother with the leak down test. make them take the head(s) off and then they will find out what is the problem.

Good luck forcing the dealer to do anything on a motor that still runs. My advice is save yourself alot of trouble and "help" the problem become catastrophic so the dealer has no choice. It is sad that automobile service has come to this but time is too valuable to spend it arguing with some service department clown. When your truck is hauled in with a windowed block or broken crank you won't have to argue about anything. |

Ron,
Thanks for the comments. It is something that I will suggest is a potential cause. |

You can try to break it on the road but holding enough continuous rpm to do any damage is hard to do and it gets old pretty fast. I suggest you take it somewhere out of the way and jam the throttle wide open in neutral and go do something else till it scatters. I do not advise draining any fluids, running without an air filter in a gravel pit, or swimming lessons at 6000 rpm. You want a nice clean catastrophic failure from undetermined causes just in case the dealer gets suspicious. |

outright fraud against a warrenty company that underwrites it for land rover?
so where does that leave you ,above the stealer dealer or below?
armen, just go show them the results you came up with, tell them last chance fix it or fight it out in court.
dont lower yourself to there level, keep fighting the good fight. |

Fight the good fight?? Against a company that is now backed up with the entire legal horsepower of Ford motor company? Knock yourself out goofball, and then when you have wasted untold never to be reimbursed hours and thousands of dollars on an attorney and they tell you to pound sand for satisfaction, what are you going to do. Most dealers will string you along kissing you in the ear and telling you they will go to bat for you with LRNA until the warranty period is tolled then, adios amigo. As for your accusation of fraud where does it say in the warranty documents that you can't leave the SOB revving 6000rpm in neutral for 3 hours? Or drive 300 miles in second gear at 80 mph? I am not advocating this solution right off but if give you them ample opportunity to fix it and they decline then take off the gloves baby. Life is too short. Besides if this happened enough car companies would have to abandon this "just ride out the warranty period" mentality altogether. |

JE,
wasn't there a big issue with ZF4HP22 transmissions at high rpm in idle? Land Rover may have its version of the ZF modified, but the BMW version (as well as many other european makes) had some problems -

Call Ford investor relations. Talk to someone there and get a contact at corporate. The higher you can make a contact the more likely it is that your problem will be solved. |

All NAS Discovery transmissions were built with the updated fluid flow pattern that bleeds the pressure off of clutch A. The problem was solved in all transmissions built after 1988 for all makes. |

"As for your accusation of fraud where does it say in the warranty documents that you can't leave the SOB revving 6000rpm in neutral for 3 hours? Or drive 300 miles in second gear at 80 mph?"
this would all be seen as a case of abuse under any warrenty and with the complexity of the OBD they may? be able to tell what was happening during the failure.
mercedes, BMW ,and cadillac all tought there OBD systems to be keeping temporary logs for diagnostic purposes in car failure or crashes.
my point is give them one more chance then hand it off to a suit and then you fight a warrenty company that underwrites the warrenty. not ford motor company.
chances are it will never go that far, the squeeky wheel gets the grease. one letter from a well stationaried law firm can do wonders where all the "I'll never buy one again" threats fail.
lets face it LR's real market "yuppie mall crawlers" most likely will never buy again any how so if you just go away who cares.
they plan to change that with the freelander but they need to change there thinking to get that segment of the market place.
dont believe it... Honda would replace that motor lock stock and barrel with 1 mile left on the warrenty and smile all along....and thats why they have gone from import trash to the most reliable best backed in the industry.
you cant fake customer support.
lets hope that some of kyles 3500 hits an hour are LR warrenty people!

Gentlemen. All this talk of fraud and vehicle abuse has me worried. Have our morals truly sunk that low? Please don't forget the 2x4 soaked in motor oil method of persuausion.
Thank you,
a concerned Land Rover owner who agrees with Musky's final statement. |

Arman,
In an earlier thread didn't you say you bought this truck used from the dealer? If so, they SHOULD fix it, but it just goes to show that you need to check this sort of thing out beforehand, even if you're buying it from the dealer. "Piston resonance" indeed.
If your dealer has any character at all, they'll fix it, and it won't be a big deal to fix. On the other hand, if they don't do the right thing, you can always tell your story in the internet and cost them some business -- and it will cost them a lot more than what it would have cost them to fix your motor in the first place. Believe me, their cost is only a small fraction of what they charge their customers. If they don't cooperate, just tell them that. How much will it cost them in the long run if you steer just one would-be buyer away from them?
As for Honda, while they have bullet-proof products and a company that stands behind them, they also have some slimey dealers out there.

Put down the crack pipe and step away from the computer. Rover's ECU can barely get the motor to run most of the time much less record all the sensor inputs and store them for future reference. |

LOL!!!
I wholeheartedly agree with your comment. If disconnecting one's battery wipes out memory, and a failed alternator can cause many thousands of dollars of damage, I'm not too worried. Ask me how I know about the alternator issue. At the rate I'm going, it's a good thing I don't like ABS.
Hell, you could use the stored memories of the ECU to argue that the damned truck had no idea what had happened. "What do you mean the ECU says I had it idling at 6,000 for four hours", "I was driving home and just hit the driveway when it went Bang!" I used to have a friend who decried scientific instrumentation with digital readouts because barely educated analysts couldn't tell when the result was BS. Something you could see readily when you were watching a meter needle swing. Just go over to the RN bulletin board and see how often somebody will suggest going to the stealership for a testbook read when basic mechanical/engineering knowledge will often get you much furthur.
••••••-tee hee hee. sorry Kyle, I couldn't resist.
Peace,
Paul |
