See quiet a few questions about the head gasket of corse the new gasket was fitted you cannot reuse a head gasket wen Chris is sliding the head on the new one can be seen
Hi Rob great video as usual, i used to have to lap the valves in by hand in the "good old days", We used to reuse copper head gaskets back then on model T Fords LOL :-)

Who ever said this is clearly not a Subscriber. 🤣🤣🤣🤣
@@nicnak4475 they couldn’t be used twice anymore 👍
Like you would put it on without it
He is an absolute demon on the tools and it is good when Chris opens up a bit and parts with his knowledge.
Get the old rubber sucker out,lol.
Nice little prod from rob to chris to explain the valve failure ,get him doing more he's great...
Anybody else did that little smile when Rob shouted "YES!!! Listen to that!!!" Brilliant guys.
Definitely an eureka moment 👍
Yeah beeming from ear to ear cheered me right up ha ha
It’s was that emotional I burst into tears!
Better than Wheeler Dealers!! When Ed China was doing that programme at the beginning they used to show more such jobs, but then it descended into a US-style wham bam thankyou mam programme. This is what people want to see - something that is educational and helpful when doing your own jobs. Lapping valves etc isn't for everyone, but there are a lot of people for which this is very helpful. A great video - honestly.
I watch Wheeler Dealers, but it's a bit fake, The buyers and sellers are just stand ins. and the way they rag the car round a track at the end is a bit naff. I think I would rather have a Salvage Rebuilds car than a Wheeler Dealer car.
Yes, well said 👏. Couldn't agree more.
Yes and it gives you confidence to work on your own car. I have a mk2 XR3i and I do most work myself. It’s amazing just by watching UA-cam channels how much you can learn. The best practice I find is just work slow as take your time. You make way less mistakes and don’t end up with scuffed knuckles!
BMW have engineered a bit of British Leyland unreliability into the mini, to make it properly authentic.
It’s a Peugeot engine 👍
@@sruk 👍 yes, Psa and BMW engineered
Abit leyland were better them new mini are shocking then again anything after 06 by bmw isnt much better that n47 engine should be for blocking holes in engines
A series was a great little engine :)
😂😂😂
I remember doing that old school , with a sucker on a stick.
Me too I use to have to do it by hand when I was an apprentice .
My dad made me do it coincidentally in a mini altho it was 35 years ago lol
Well done Chris we need to here you talk a bit more 😆
Hear?
I think you might have hit the nail on the head with the odd injector in that cylinder. If someone has mistakenly fitted an injector from a standard Cooper rather than a Cooper S to number 3 then that cylinder is likely to have run lean, and therefore hotter, until the valve has burnt out. This is because the naturally-aspirated Cooper has less oxygen in each cylinder on the power stroke, so it can only burn a lesser amount of fuel on each ignition stroke. The Cooper S is turbo-charged and the forced induction means there is more oxygen in each cylinder when it fires, meaning it can burn more fuel, which is exactly the premise that forced induction works on. More oxygen means more fuel can be burnt which means a bigger bang. The Cooper S injectors are likely to fire a bigger shot on each pulse, standard Cooper injectors will fire a smaller shot as the engine won't be able to burn the extra fuel in standard tune so the unburnt fuel will just end up poisoning the catalyst. It seems pretty obvious that the damage to the valve was heat-related and not a mechanical failure as there's no damage to the turbo blades, so that metal had to be molten when it went out of the exhaust valve. If it had just mechanically failed then there would be turbo damage and, probably, a lump of chewed up valve stuck somewhere as there's no way a piece of metal the size of what's missing from the failed valve could go through an operating turbo impeller without causing a lot of damage that would be very easily apparent. It does rather seem to add up in a way that makes sense...
Lovely job guys, and a damn good sign that you've hit the issue squarely on the head with that one. There's no way on earth it would run that sweetly after going back together if its' issues were down to the engine just being plain ragged out. There's still a chunk of work to go and a decision to make on whether to put a set of injectors in her rather than just the mismatched item, but you've got your proof of concept, the engine's back together and running as sweet as a nut which has got to be such a satisfying feeling...
But it was coked up so running rich instead of lean.
Unless the coking happened after the valve burned ?
@@johnmoruzzi7236 Yes, that's most likely to have happened after the valve failed. The mixture won't have been fully compressed in the cylinder so it won't have burnt fully, and then the exhaust port being much cooler than the cylinder due to being cooled by the coolant running through the head will have allowed the coke to deposit in the exhaust port when it won't usually be able to do so due to being driven through by the piston returning up the bore...
Back in 1966 the gearbox seized on my first car, a moggy 1000 traveller. So my mate and I built a homemade derrick and yanked the engine and gearbox out in the street. He went to the scrapyard to find a replacement gearbox, which he actually managed to stuff in the bag of his frog eyed sprite, and did a de-coke on the head on my living room floor. I did all the grinding in by hand and boy were my hands sore. The moggy ran like a sewing machine for another 3 years until the floor fell out.
Rob not to dismiss your ability, obviously your a top man at everything you do but how reassuring it must be to have Chris as your partner, the man's on another level to most people out there, the stuff we've seen him put his hand to and complete to the standards he does is just unbelievable, and he does it all in such a chilled out laid back manner, watching you guys work together as become addictive, could honestly watch all day everyday,
Thanks Chris, You have a great voice, it was a pleasure to hear it for a change! More please! 💙
No Waffle on Chris or Constant Apologies 🤭
The excitement in your voice when that started was worth it
Never known such excitement when the engine kicks into life 👏🏻
The relief of that first turn of the key and it fires straight up and sounds sweet will always make your day and go home happy !!
I look forward to coming home from work and sitting down to tea watching your vids, nice end to the day.
I always love it when people get excited when the engine fires up after a rebuild! I've done it enough times and there is always a grain of doubt isn't there. Well done gents.
Fantastic job it sounds great. One of my first tasks when I started in a workshop 26 years ago was lapping valves in by hand in a Nissan Cherry using the little wooden baton with a sucker on the end. My hands hurt for days after!
Rob - ignore all those trolls who post negative comments. Never be ashamed of yourself, just remember there’s over 150,000 people who love the work you do!
I’m not bothered and definitely not ashamed far from it 👍
See so many "mechanics" lap valves in, spun one way with a drill. I'm not surprised in the least to see Chris doing it properly with reciprocating tool. P.s. film quality so much better without glare of white trainers.....
Always amazed when watching two craftsmen at work. Great job guys.
Chris is one hell of a Mechanic! Rob you have the gift of the Gab 😂
Watching Chris lap those valves in made me wish I'd got that lapping tool back in the early 1980's. I had a Series 2A Land Rover that blew a head gasket, so while the head was off I fitted new stem seals, and lapped all the valves in using the old stick and sucker between the hand routine. The car ran a lot better afterwards, but my hands took forever to recover. Looking forward to the next (final?) video on the Mini
i love your excitement when things work out . the smile is contagious
Fantastic result well done guy’s nice to see Chris back in the workshop.👏🏽👏🏽
That "yes!" Was perfect haha
Chris nailed it with his second guess as to the valve damage "bad engine design"..
Yup..Things have moved on. Used to lap valves using a stick with a rubber sucker....:-)..
What a fantastic explanation of everything good to see Chris with so much knowledge he knows his stuff and isn’t shy to get fully involved in everything.
Lapping the valves into the head.when I was an apprentice we used to call it grinding the valves in
Rob & Chris great result. The two of you are on fire as always. 👍🏻👍🏻👍🏻🏴
Before I watch it I know it’s going to be a good video, been on UA-cam for less then a minute and already comments lol 👍🏻👍🏻
Love how Rob gets excited when it starts, like a kid at Christmas MAGIC 👍👍👍👍👍
Rob take this as a compliment as much as I enjoy you waffling it's great to hear Chris getting involved and explaining things. Thanks again for a great vid .and yeah the mini sounds great .
I swear Chris is a magical being? The man is a mechanical professor genius. LEGEND 🙂👍
Nice work .no skimping on this channel .all new chain and oiled in the bag for an hour .it sure paid off the attention to detail.knew it was gonna fire up immediately and quietly .well done guys !!
Love the enthusiasm,and the confidence that you both have,👍👍👍
Another really interesting video glad to see you both back and well. Good to hear Chris chatting too! Always baffles me how you remember where everything goes when you reassemble 🤣
You guys do go that extra mile, i would have no problem buying a car and recommending you to family and friends. 10/10
The time lapse music was great, and to carry on the music where it left off each time, made the video even better. Lovely work all round. Thank you.
Really enjoy your videos, lovely genuine fellas. I have a little enthusiastic mechanical knowledge, but love that you just get stuck in. Keep up the good work!!
That YES was everything 🔥🔥
Greeting from Houston, Texas, love your channel, great work! thanks for your Vlog. Mac
Nice to here a bit more communication between you pair. Chris obviously the quiet thinker👍
Have faith in your work, you sound so surprised it started
What a result. That sounds beautiful. Rob your face was a treat to see you so chuffed with what you both have achieved. Well done guy's.
Hey everyone! Rob’s got boots on!!! 😱
Trainers are at the paint shop 👍
@@sruk what colour you going for 🤣🤣🤣
All the talk of lapping, I am lapping up all your great videos, great stuff Rob and Chris.
Lol 👍
Great way to start my Wednesday evening!
Hearing the mini run smoothly is a win. Great Job 👍
Another good video god Chris waffles on lol enjoyed him explaining what he was doing maybe more of that and Rob at least sound excited when it started 😆
Brilliant channel very interesting amazing how small things can stop an engine running carry on guys love it
Love the lapping in tool guys l I remember having to do them by hand.
Good to see it running, if those injectors are cheap I'd just replace them
I did tell you in the last video to replace that oil pipe ......
Absolutely beautiful work. Engine sounds just like new!!
Hi lads, I was well chuffed when she fired up in to life. I was more excited about it than you rob, just got to wait until Friday now to see her finished, great work lads 😃
Love the way the two of you work seamlessly together 👍👍
I don't know why but I am properly into this. I find it so interesting watching the cars get taken apart and built back up when fixed
Top one lads
Much love boys 👍👌
Monday’s Wednesday and Fridays are my favourite days in the week as I know there’s going to be something good to watch on UA-cam when I get home from work. Loved Chris in this on with his little demos and explanations, rob please include more of that. Being a mechanical engineer myself that’s the stuff I love and I’m sure everyone else loves it too. Adds more to it. Great video as always well done keep up the good work.
Ahh brilliant,,,great job men,,I feel the same joy as you rob when it starts up like that,,and it ain't even my car
Well done Rob and Chris, you have a great job as usual. Waiting for the next video. Have a nice day, cheers guys.
Great to see Chris on here, another great video, well done lads!
Well done guys, nice little motor and big thank you on showing how to change the chain. Look forward to the next one.
*Brilliant, like a Swiss Watch.*
Glad to see that Rob has a proper pair of shoes on today .i have often thought that trainers are not suitable for a workshop
Nice one can't wait till she's done and up for grabs
Great work and superb video shots too. The channel gets better and better 👍🏼👍🏼👍🏼
Love this "channoo"! 🙂
Jeeez! That engine sounded like a bag of spanners when you guys first got it in. Sounds absolutely sweet now. Nice one guys!
5o Clock just clocked off and Great video to watch made my evening start the right way
Really enjoyed that video rob, looking forward to the next one
Put a Wang on Chris haha
Nice one enjoyed very much 👍🏴
I couldn't see a head gasket when you put the head back on. Ive done valve lapping and found it very frustrating to get the seal, did you test it?
Of corse 👍
The best part of this channel is the genuine enthusiasm. Binge watched a load of vids last week, so much that I started thinking in Robs voice 😂
Excellent!! And it’s also nice to hear Chris talking more and sharing his vast knowledge well done you two on the rebuild 👍👍👍
Loved this one fellas. Bit more of the engine rebuild content would be great.👍
Excellent job guys. You make a fine team and, as a few have already said, yours is one of the best channels on UA-cam. As always, loving your attention to detail. Rob, your comment of "It would be criminal not to while it's all apart" is what sets you apart from the cowboys. Glad to see you're both back and fighting fit. Ian.
Once again, another great and informative episode.
It was exciting at the end!
Well done for saving the Mini by solving the engine issue!! 🙂👍
I love how excited you get when something works when the engine ran for the 1st time and when you turned the hazard lights off on the 2020 Range Rover, fair play you don’t cut corners and anybody who buys a car from you is going to get a very good car for years to come 👍🏻👍🏻
Hello everyone, as I’ve said before, please no personal comments about Rob’s spelling etc. I’m dyslexic myself, but have practical skills and abilities. You can see Rob is very talented and we all should support him and Chris.
These people criticizing probably have their own problems, no-one is perfect. They're just nasty
Interesting video enjoyed use explaining the fault and reasons maybe why it failed, good work again lads sorted 👍👍
Chris is amazing at explaining, we need more of him talking on the channel ,
Yes. He needs to open up more. We're not interested in how he looks or sounds. We just want to hear the knowledge that he has and learn.
Great job lads. Rob your like kid in a sweet shop when it starts 🤣🤣👍
I always love your content, Chris is so clever amazing. Thanks again both of you. Can't wait to see her finish.
Great video. Delighted it fired up so well after all that work.
Loving your safety boots Rob 👍👍👍
better than top gear because you explain the details. brilliant video.
I have to say Chris is a superb engineer . Nothing is a problem for him ! Love the vids guys . So interesting! 👍
Another great video guys so informative 👏
Awesome, good to hear Chris at last 👍
I can feel your excitement here in Australia!! Well done. These BMW Minis are not like the old Coopers
Another great video... keep up the fantastic work 👏
I pee myself laughing at how excited you get when it starts lol.....
Boom! Another great video guys. Can't wait for the next instalment.
Really enjoyable video
Great video again guys!
Good to see DJ Chris on the engine block again. Cool music. Channel keeps getting better and better 👍
