Hallo everybody Recently I changed de windscreen and seal on my Discovery 1 (seal: MWC8304).l bought the seal from Paddock and was a Britpart produkt but when I placed the seal around the windscreen : He was 1 cm to long on the vertical sides of the windscreen.I bought a second one from Britisch car parts and this part was marked as : OEM parts . I think that both seals are from the same brand . Anyone with the same problem ? Martin

hallo everybody Thanks very much for the fast respons.To avoid the misfires I lowered the setting of the waste gate at 1.2 bar instead of 1.3. The turbo is still the orriginal one.Some times I recieve the message "overboosting" but not always.(nanocom evo). I think I will contact an automotive software programmer to ask what he can do about this problem.(he downtuned our IVECO Daily's in a special way).Last visit we talked about tuning the TD5 and the possible problems,maybe he can do something about it. Normally I dont need the max power but when towing my caravan in the ardennes your lucky with every hp and Nm under the trottlepedal.

Hallo everybody I run a TD5 M.Y.2000 with a tuned ecu 150hp and 360 Nm,the turbo press.is set at 1.3bar with the actuator rod length,but when accellerating the turbo press passes slightly the 1.3 setting,at 1.35 the engine starts to misfire.The MAP sensor is new and the range of the sensor goes up to 2.5 bar (MHK100640)(BOSCH 0.281.002.205) I think there is a limiting setting in the software to protect the engine.Is this correct?? and if so is it possible to change that setting,(1.5 bar)??? Is there somebody who knows more about this subject ?? Martin Gent Belgium

Hi everybody Thanks for your wise advice !

Hi everybody I own a td5 m.y. 2000 with the engine tuned at 150 hp,it performs very well but when towing a caravan uphill at full power there is a sissing noise probebly from the exaust collector,the collector is bending at very high temperatures and the gasket can't take it any longer.The noise disapears after 5 minutes when the engine is running in normel conditions (50/60% power output). I know that Land Rover made a mistake by making the exaust collector (of a 5 cylinder) in one piece.(they made several other faults aswell but thats an other story). Now my question: Is there a good solution fror this problem?? Or is there an alternative solution on the market somewhere ???

Hallo guy's First of all many thanks for the replay's on my topic. I have seen most of the comments on the timing gears,one thing is for shure they are verry noisy, and most off the people who installed them where not happy,some ended up in an engine dissaster. There is a splitted gear in the set to prevent backlash between the gears did they respected the tension of the spring in the pignon?normally their there sould be no noise on idling ?? Thats strange,because I am working on wheel loaders now for at least 25 years and most of them are equiped with Kubota engines with gear distribution system and what's more we never had one fault on the distribution system.Most of the engines died with a totally blokked air filter or with a leak on the filterhousing.(terrible working conditions in demolition situations). I have never seen any wear on the gears an what surprices me is that their made of a soft material and not hardened at all.Those gears have no backlash system and I can't hear them running. My conclusion is :not to install them on my 200TDI Disco for daily use but to install them on the engine of a disco 200 TDI wich I bought for spare parts.The engine is still in a good condition. So we will see how it will end. Until later. Thanks again Martin De Smet Gent Belgium

Hallo everybody Is there anybody on this forum with a gear set distribution system from Zeus ?? Many years ago I bought one ,and now the timingbelt needs to be changed,but before starting such a big change I would like to hear if there are some members with this gear set running on the Discovery. The work itself is not the problem because I am a mechanic and I work on engines on a daily basis.The question is:is this system reliable,and what's the noise level of the gears when ideling ???

Hallo,it must be a breather pipe on the backside of the actuatormembraan above. If I'm correct,it is best to turn it with the rubber pipe down. Martin Gent Belgium

First of all a happy new year and lots of fan with your L.R. I have here some files with the voltage graphics of each of the injectors of the TD5(MY 2000) The graphics are measured at 740 rpm stationary.The time between the positive peaks is 160 msec. The top of the peak is at approx.80 volts. The negative peaks between two positive ones are respectively those of injectors 2 4 5 and 3. I havethe intention to continue the measurements on the road on different speeds and loads. Many greetings from GENT BELGIUM Martin.

Hallo everybody See message from robK007 on the Discovery forum please,problem solved by lowering the turbo pressure of 0.1bar from 1.1 to 1.0bar,the MAP sensor informed the ECU that the turbo pressure was to high so the ECU lowered the quantity of fuel injected.(the so called misfires !!!!) Many greetings and thanks to robK007 Martin Gent Belgium.

Hallo robK007 Iam driving a Defender TD5 and have exactly the same problems,I had planned an electric surch for that problem today but your message changed my plans and I toke the actuator out of the car,the shaft of the wastegate was free to move but I tested the opening pressure and I noticed 1.1bar to START the movement of the rod at a length of 42.5mm (between the housing and the nut) I changed the length to 47.00mm and the opening pressure changed to 1.0 bar.I made a test run and the problem was gone!!!!! As you told the MAP sensor informed the ECU that the turbo pressure was to high and limited the quantity of fuel injected.(the so called misfires!!!!) Thank you very much it saved me a lot of work. Many many greetings from Gent Belgium Martin (Disco111)

Hallo L.R.lovers First of all thank you very much for your answers.A year ago I noticed OIL in the harness,plugs and ECU plug,I changed the harness inside the cylinderhead cleaned the plugs and prevented that oil could come in the ECU plug by cutting the 7 wires (2 earth connections and 5 signal lines from the injectors)I soldered the wires on both ends and placed a connector in between. It is now impossible for the remaining oil in the harness to reach the ECU plug.The only things that remains is the risk for problems in the plug on the cylinderhead and the insulation of the harness itself.(I think). As I promised, a hour ago I have done some measurement on the injectors,I placed my multiscope meter on each of the lines and noted at 740RPM a peak tension of 100 volts and when revving at 2000/3000 RPM more then twice that tension !!!! I can now understand that the oil between the contacts can lead to an electrical by-pass between the contacts of the connectors or even between the wires themselves. Now I am gone check al the connectors again cleaning them and inspect them before taking any action. See also my message:"TD5 INJECTION TIMING",on that subject there is also a lot to explain I think. Many greetings from Gent and thanks again,untill later. Martin.

Hallo Jason It as certenly nothing to do with a mechanical problem in the drive train.At a speed of apprx. 100 km/hr the engine starts to produce misfires(aprox.2400 rpm).Normally I dont drive more then 100km/hr and each time I reach this speed the engine starts to misfire.This week however I was on the highway and passed 120 km/hr whitout the typical noise that I normally had.Then I realised that on that moment the engine was running 100% normally and that I have to look for the reason of the misfires.(oil in the wiringloom). I know the problems of the oil in the harness but nobody until now on this forum explaned whats realy going on in that harness and in the connection plugs. I have seen on my multiscoop that the signals to the injectors shows very sharp pieks so I think that there is a certain electrical leak current between the contacts of the plugs contaminated with oil wich in turn produces the misfires from a certain regime of the engine. As anyone done some research on this subject,anyway this week-end I am gone do some tests and measurments. Many thanks and greetings from Gent Belgium Martin.

Hallo everybody A year ago I replaced the harness to the injectors inside the cylinderhead because there was oil in the plugs and wires.I cleaned the plugs and made a barrier in de wires just before the red plug by soldering the seven wires.Each time I reach the speed of 100km/hr the engine starts to make a strange noise(I think there is still a problem with oil in the harness). Does anywone as an exact explanation whats happening in the plugs or wires,is there an electrical leak current between the wires or inside the plugs so that the injector exitation get disturbed??? A new harness between the cylinderhead and the ECU is very expensive (+400£).I can make a new harness myself but first of all I wish to know whats exactly happening inside the wires. Many greetings from Gent Belgium Martin.
