Remember, the design department never ever talk to the engineers who never ever converse with a mechanic.
Patience and persistence of a Saint!
Great job Mike.
Cheers for sharing.
You got that right!
Well done Mike - glad it turned-out simple in the end. As the good man South of you says : There's old parts, new parts, and good parts.
Winston Churchill also said,
“ This is not the end. It is not even the beginning if the end. But it just might be the end of the beginning.”
And he did like his Land Rovers!🇬🇧
I’m pleased you got it fixed 👍🏼
Thank you!
I have been down all day thinking about your problem whilst sorting a 72 series 3 V8. Up and running after 33 years, a Townley conversion used by the MOD at Shoebury ranges. Still glad to see a smile back and have another wee dram. Best wishes from the UK.
Thanks man!
Hang in there Mike, nice job on the diagnosis. Recently had the same problem with Champion plugs but no fault codes as running megasquirt / gems. Was misfiring and smelling of fuel. NGK fixed it.
You had to look carefully at the plug tester to see when it missed a beat or two
to ( sort of ) quote Churchill ' never surrender ' .. nicely done Mike
just goes to show that you can never tell :) glad you got it sorted with such a simple thing
Absolutely!
I am Happy that you solved the issue.
I feel your pain. I have a 99 disco 2 Bosch 4.0 automatic. Engine light came on code was cylinder 7 misfire. Bla bla bla. Replaced the plug same code came up. Replaced the wire , code came up again. Coil packs are original. So I looking at the motor trying to figure out how to replace the packs. Lucky for me I live in the desert, and my disco is pretty messy looking. So I took a cutting disk and cut a access hole in the firewall so I can remove the coil packs . It fixed the problem.
I laughed when I saw this video, and thought I would share.
Enjoy your videos.
LoL! Years ago in my distant past, the S2a and 3 had the rear head core plugs leak - you are supposed to remove the head - but you could make a hole in the bulkhead and put a new one in! Lol!
Well done glad you have sorted it with the help of Mr Jamieson !
Thanks 👍
Glad you got it sorted. It's the same with my car, the whole intake manifold has to come off to access the 3 plugs on the left bank. Designers don't go to the same meetings as the folk who have to service the things. Remember when changing a bulb was easy.
Great videos. I've been watching u since 2015. I've restored 25 Disco and Range Rovers and got them back on the road. Keep on sharing Sir!👍
That is awesome!
glad you sorted it, we forget a spark plug is just an extension of the wiring loom 🤭
Yeap!
Well done Michael.
Well done for finding that ,i find it so frustrating when its down to quality of parts failing they cause us so much wasted time,through no fault of our own.
Don't you just love it when new bits come prebroken and after hours of peeing around and money spent, the company says we'll need to test it before we replace it and you need to pay for postage to send it back
yeap!
Well done boss, you are not one to give up, you have your mojo back !! Until the next Land Rover battle 😋🤪
We shall see...
@@BritannicaRestorations you are a very hard worker, maybe a little break from it all would help..
Would be nice, but I seem to be the go to place for LR problems!
@@BritannicaRestorations The down side of being very good with land rovers
Well done. Satisfaction when you finally find the issue. I think everyone agrees sticking with Tdi powered stuff.
Keep up the great work.
Regards from Gavin in Kent🇬🇧
Thanks 👍
Patience of a saint, call me old fashioned I'm sticking with my carburettor and distributor.
Good work! Well done!
Regards from Norway🇳🇴
Thank you very much!
Nice save. Good old Brit` spirit, get angry, stamp about a bit and then get it sorted.
Well done Mike. Love the videos keep ‘em coming.
Thanks, will do!
Glad you got to the bottom of it., Sucks it was a faulty new part though., And how much extra time youve wasted. Keep the vids coming, id be lost without them 😉👍🏻
Why not work on these, you are an expert on them now!? (Lol)
As I said a while ago, some things on Land Rovers are absolutely brilliant, others were designed and made by first year apprentices on Friday afternoon just before going to the pub, or maybe as a brain fart while at the pub for a few hours. I feel you. 😢
Champion plugs used to be standard fit on almost all British stuff back in the 70's and 80's and they were never much good. I always fitted NGKs if I could get the right grade.
Rolls-Royce dropped Champion in the 70's = if it was good enough for them, it is good enough for me!
Good work 👍
Thank you! Cheers!
Winston said “ if your going through hell keep going “. But he never had a landrover !!
But he had a Series One as an 80th birthday present. And amazingly it took ten years to finish him off !
@@philhealey4443 , Brilliant 😂
CHAMPION REP was 'TOO CONNECTED TO ''THE LODGE'' we stuck to NGK
When I was a workshop supervisor at a Peugeot garage the service manager asked me to go to a local bodyshop where they had repaired a 405 but couldn't start it; it was a love job. I grabbed a set of plugs a tech. had just changed doing a service, cleaned and gapped them and fitted them on site. With the battery booster connected the car still wouldn't fire, nothing at all. We towed it to ours, fitted new (from the box) plugs and it fired up first time! How could plugs just taken from a car driven to us for service fail during replacement? I have no idea.
Bish Bosch, Loads of Dosh!
Well done
There's your problem! Champion plugs! I'm sure Joseph Lucas had a hand in their design.
Never had a doubt you would fix it
Thank you!
🥳🎉🤩👏 well done! Fingers crost! Get rid of it quickly before something else breaks!
Great work Mike 👍 all the work u done I knew it wouldn't be much. Shit plugs. Crazy. 👍👍👍
Bonkers! Many thanks!
Is this a case of oh we need a new coil pack well we best put a head gasket in it while we got it stripped down?
Mike the Priest?! Now there's a thought. You do actually sink a lot of Jameisons like some of the Priests I remember! But your landy flock need you more!
i bought a set of ngk's for my rover v8 and replaced the old plugs even though they were good. I was chasing a misfire for a few weeks and it turns out one of the new ngk plugs were bad. quality control these days....
So it wasn’t the Rover then! Ya daft ha-porth glad it’s all worked out 👍
i ones had a champion plug , where the ceramic fly out of the plug metal base , during driving ! Im wondering how much RandD goes into making a car easy to repair. Toyota your favorite , you have to lift the cab of the frame to get to the turbo , also V8!
the next doors will be wondering why their dog is collecting spark plugs..................
🎉 well done.
You're the Man.
Tata
Cheers!
@@BritannicaRestorations if I were you, I would take a bit of time for a little talk with mr. Jameson's. 😁😁
Never had any faith in Champion plugs. In my youth I ran a Honda CB72, it destroyed the recommended plugs in seconds, NGKs lasted at least 5,000 miles.
Do you get much bother from yer neighbour fella? 😂
Well done for sticking at it.....me and Mr Jameson knew ya would tho...👍
Not at all - but his garden is a mess…
@BritannicaRestorations 😂😂👍
Well done the jamesons always helps in my opinion 😅👍
Always!
Jameson for inspiration
Brain lubrication - or relaxant!
Got to admit it was a bit of a scare thinking you were finished with land rovers but glad you got it sorted mike, grewt vid and thanks
Thanks 👍
Did you read my comment about removing the engine mounts, to drop the engine down to access the coil packs better, it worked for me, they are held on with torx studs.
I've always said Champion plugs were to be avoided, never had a bad NGK one
Plugs were supplied by the customer
dont worry , the next problem wont be long in turning up .
Always use original Denso or NGK , and check the gap yourself. Don’t take someone else’s word
It has come to my attention that the quality control on spark plugs isn’t what it used to be. When they say they come pre-gapped it doesn’t necessarily mean they were pré-gapped properly. Champion seem to be the worst defender of this now.
I was told at standard flooded batteries are actually 25% lighter than they used to be 20 years ago. That means they have 25% less lead in them and it shows because I found that batteries don’t seem to last more than two or three years now for if you’re lucky. I recently switched over to AGM type batteries and that seem to have better luck with them. I know they’re more expensive, but if it comes down to paying some more money and getting stranded 40 miles from home I’ll take my chances with the extra money.
I like AGM batteries. However, some a better than others
6 years ago I bought one of these for my Defender
www.odysseybattery.com/products/odx-agm24-battery/
Was expensive. Lasted 12 months and would not charge
They sent me another, but that only has half the power now - but good enough for my Perkins in the fork lift
May get another AGM, but not an Odyssey
Those plugs could be knock offs, Mike. See a lot of that here.
Solutions by Jameson's.... They should be sponsoring you.
Yes I was thinking about that...
What a bunch of muppets that designed that enginebay.. and then call it a car that can go anywhere? They should add that it'll probably stay there...😅
Oh Mike: wrap up the work on the Landrovers (i love them). Take a good long vacation and start again only doing Toyota hilux, And then only the simple ones, I have one never have problems, 😄
Hiluxes were not imported into Canada - there is some strange rule to protect US pickups, that manufactures must make pick-up's in the US
I think every distributor ignition vehicle needs to go on a Crypton style engine analyser before leaving the workshop. I think your dodgy plug would have shown straight away with a raster trace
I have had fake ngk spark plugs from ebay before and it took me so long to diagnose a missfire on a honda outboard before i got another set and realised the plugs must have been fake
I have NGK iridium plugs in my car which thankfully is a Toyota 😀
Heh, I was going to say it's got to be the injector OR the plug but I didn't think the ECU could detect a plug-related issue that might be causing emissions problems.
I mean, the ECU knows how long each injector is open so it knows if too much fuel is going in and causing an emissions fault.
If the plug isn't firing properly, though, all the ECU knows (from the sensors in the exhaust) is that unburned fuel IS getting into the cat'. It doesn't necessarily know which cylinder is responsible for causing it.
I guess the ECU is just detecting the misfire and ASSUMES that'll be causing unburned fuel to get sent into the cat' so it flags up the emissions fault.
If the fault was simply "Misfire on Cylinder 2" (without all the emissions malarkey) you'd immediately assume it was the plug and check it without worrying about the injector.
Also, I keep saying it but Land Rover didn't do themselves any favours by cramming V8s into every vehicle they sold in North America.
If they'd sent TD5s over there, and convinced people to buy them instead of trucks with a V8 in, things might have been very different today.
Don't forget these engines have knock sensors on the sides of each bank - they listen to the firing of each cylinder - if they detect a misfire that is out of range, it will throw a code
Clever stuff - but also these sensors are responsible for detecting 'rough road running' and one of the causes of the 3 Amigos coming on the dash
Now one would have thought that 'rough roads' were part and parcel of the LR world, but no - it deactivates the traction control, which is maybe why they went back to a manual diff lock in later vehicles
The Bosch 'Thor' system can also detect an iffy combustion via the difference in acceleration of the flywheel on a power stroke. Couple that with knock sensors and the system can be too clever for its own good 😀
@@GavinEarnshaw I wonder if it DOES do that, though, or whether the fault-code generator just automatically creates an Emissions code at the same time as a misfire code?
Just seems needlessly convoluted to me.
As I said, when I saw those code I immediately thought "It's gotta be a plug or an injector" but then all the stuff about Emissions makes me think it must have detected fuel in the cat', which makes me think it's an injector fault.
Course, once a mechanic is familiar with how the Thor ECU "thinks", they're more likely to be able to correctly diagnose the problem.
I had a similar thing, recently, with my wife's Mini.
Dashboard lights for the ABS and stability control were on.
Scanner revealed a bunch of signal faults in the ABS system, which made me worry that something expensive was wrong with the ABS system.
Fortunately, I also noticed a code related to the MAF sensor which DID say "below expected voltage".
Problem turned out to be.... a flat battery!
Which the super-smart ECU didn't see fit to mention anywhere.
@@SiCrewe I read up a lot about the Bosch system when it was launched but I don't remember if it automatically put a presumptive 2nd fault code on. I did get fed up with Lucarse 14cux and gems so built a Megasquirt 2.
My son is a mechanic and as an apprentice only 3 of them were actually interested in understanding why it was wrong. The rest just did what the fault code said.
A total lack of systems engineering and silo mentality all around. Like you said checking the basics first.
Codes?
You'll be glad to be rid of that Rangerover too.
You definitely need to stop doing the big jobs.
Lol, re my previous COMMENTS..thor...good engine...BWTF...coil packs in the hottest place ever...traded my disco2 for an FQ330 evo...now they are in a different league with complicatedness ...
BET YOU FEEL BETTER KNOW YOU HAVE FOUND THE PROBLEM WELL DONE MIKE CARRY ON REGARDLESS
Really got screwed in the arse over there with the emission crap
My thoughts and prayers are with you Mike :-)
Champion eh, Chinese rubbish. NGK or Bosch plugs for me.
Never liked Champion plugs. Used to rate NGK, but not nowadays. Best quality and value by far imho are Denso. Never had a bad one.
I ran all sorts of petrol transits, late 70s early 80s, local guy only supplied champion spark plugs and in order to keep it going (delivering milk, stop, start, stop start) they got new plugs regularly, and regularly 1 of the 4 would be faulty!?!?
I was half expecting to see you standing there with a big grin and an empty petrol can in your hand...
Almost!
well done, this stupid plastic bowl learned its lesson, never mess with king mike ...
I don't think these cars are hard to work on. I bought a 2000 P38 because it had the rare factory winch mount and Warn winch. It didn't run right. Hawkeye Total said misfire on cylinder 7. Changed plug. No difference. Changed plug wire. No difference. At this point it has to be the coil pack or the injector. You have to remove the upper manifold to get at either so I replaced both. Problem fixed. I doubt it was the coil pack as they rarely fail and I believe if it does fail you will get a misfire on at least two cylinders. I am not a professional mechanic.🙂
Poxy connections ;)
I wont even put champions in my lawn mower, they used to be good but not any more.
😊🥃
Wow
And all it was, was a weak plug ?!
Erratic (or erotic ) firing
Good on ya Marra for unfucking the Disastery 2.👍🏻
Churchill apparently also said, if you find yourself going through hell, keep going.😉
04:47 there's your problem mate, Expert= Ex is a has been and a Spurt is a drip under pressure😆
There's 2 guarantees with modern vehicles, 2000ish+
1. The components are gonna be packed in and in the fucking way.
2. Parts, even from blue chip companies can be duff!.
Yeap - just takes one plug to throw the cat amongst the pigeons
Champion plugs Joe Lucas.s step son lol
Rubbish design. Love my Land Rovers, but after the TD5 and gems V8,they are expensive and difficult to work on. My opinion, the last proper Land Rovers was the Defender and D2 TD5s. 300tdi is my favorite engine though.
easy to get that sorted.. after having 2 D2's i found out that setting the POS on fire was the best solution to all the issues and bought a little Renault Clio.. trouble free for 3 years now
Good call!
Well done tracing that misfire! This set up looks like a BMW design, and I find most of these German influenced designs are a complete nightmare, you can be sure that if something electronic fails on a Land Rover it will have "Made in Germany" stamped on it, a very poor design.
it's a JONAH like every other LR piece of junk.
Stick to 300 tdi's and older...
If you first don’t succeed,try try again. Your now your local Land Rover expert.
