Man, your dad is oviously having the time of his life. He is probably the proudest dad this side of the Atlantic. Cherish the time you spend with him. Really touching to see him smile from the bottom of his heart.
Im a bit old, and seeing Father and son enjoying time together, sharing a common interest is heart warming... Makes me wish I had that type of relationship with my pop when he was alive.
Even if the car was fully functional, it wouldn't go into gear if the front latch is unlashed (common issue with the mclaren). If you want to bypass this issue - keep the brake pedal fully depressed and hold the drive (d) selector for 20 sec and it would shift to 1st gear allowing you to move.
I work for Mclaren as a Technician. If you fill all 8L into the engine in one go during an oil change it will overflow internally and cause a smoke show. Start with 6.5L then run it and go through the top up procedure.
Matt check the oil drains from the turbos, there could be an issue with them draining oil back to the sump, this will send oil straight past the turbo seals in to the exhaust. I worked on the 570’s GT4 cars, we blew an engine in qualifying at donington, we fitted a new engine over night from the mclaren spares truck, they had left a bung in one of the turbo drains, the smoke we got was 10x worse than what’s coming from your car. It could also just be the turbo seals. Hope this helps
@@kobusbotes9775 thinking a bit more, if there’s too much crank case pressure this could stop the oil draining back, I reckon there’s been oil sat in the bottom of the engine which initially caused an increase in crank case pressure, and forced a load of oil past the seals.
hi mat, you probably would already have checked it by now. but double check the oil level of the engine. if you have too much oil in the dry sump system the turbo's have difficulty draining back into the sump causing too high of a oil pressure in the drain line, causing it to poor oil past the seal in the turbo's
For me as a McLaren technician it is very interesting but kind of a pain to watch you rebuild, or try to rebuild the car. There's so much I would love to tell you how to do different or where you forgot to put in screws or bolted something in the wrong way. Just for example, looks like you forgot the screw of the 'last interior part' from behind? But anyways I will keep watching and just hope you will get it running again! (Try holding down D button when engine is running for around 10 seconds, works wonders sometimes)
@dovlatheman8344 shame you can't fix an iPhone like the mclaren. The iPhone would just disable things like true tone, if you change the screen yourself lmao.
You could easily straighten the existing rear struts, I have done it many times. I believe the turbos on the 720 have liquid cooled center sections so a damaged turbo could allow coolant into the exhaust.
I would say that's a possibility if it was out of one bank only, but being both it is more likely to be the crankcase breather system if its not the rings that have gone
@@jamiebarber4675 That doesn't really look like smoke caused by the burning of oil in the combustion chamber. It seems like the vast majority of exotic car power trains are fragile and temperamental. The parts prices from exotic car manufacturers is outrageous as there is absolutely no reason for it. A great example is the front marker lights for a Lamborghini Diablo, they sell for over $1200 a pair and they are borrowed from the Suzuki Samurai and those are $20 a pair. The Alternator for a Testarossa is well over $1200 from Ferrari and it was borrowed from the 1985 Corvette and can be purchased from any auto parts store for $120.
Looks like the oil drains on the turbos might be kinked or not positioned correctly. You'll smoke like that at idle and free revving since the oil has no where to go and it just goes through the seals. Good luck!

Yea, actual faults can sometimes be something totally unrelated to the "problem". I had an ABS/ESP light on on my Peugeot a few years ago, and the dealer wanted to replace the ABS pump for £1,000, even though the ABS was working fine, so I ran away, quickly. I eventually figured out that the problem was a stuck EGR. Basically the car didn't know the position of the EGR valve, so it couldn't calculate a torque value; which was needed for the ESP system to work. And the previous owner had blocked the EGR and deleted the parts of the code in the ECU responsible for EGR faults, so that the car wouldn't give any EGR faults. It was annoying, but it was really satisfying to logically trace the fault and find the problem.
Your dad's enthusiasm is so contagious Matt even though you are going through problems on the build he keeps it 💯 I just love that he sees the light at the end of the tunnel
Discovered this channel a few weeks ago. Massive respect for the amount of technical knowledge and determination! Funny to see you laugh at all the smoke where I would be definately crying.
Matt you are a huge inspiration to us all and a major reason I finally started my TH-cam channel. Been here since the wrecked TT and have loved watching your growth so much. Bummed I didn't get to meet you at SEMA, but excited to keep watching your journey. Thanks for the inspiration 🙏🏻
The smoke looks like burning oil. This can happen with McLarens when they sit for a long time as the oil leaks into the turbos. Let it run for a bit and see if it starts to improve. Could save you from taking the engine out.
that smoke from the engine maybe disappointing right now but those things what makes others stop or give up but anyone who watching your channel are certain you gonna find a solution anyway and thats why your channel is truly great cause you guys never give up! :) Wish you all the best to find the solution this time as well!
They would know if the smoke was oil, because it would smell like burnt oil. The white exhaust smoke was almost certainly coolant. The fact it was coming out both exhausts (ie both banks) indicates it’s not something affecting just one bank. It’s extremely unlikely for both turbos to fail in the same way, and also extremely unlikely for both head gaskets to fail. So it must be something ‘upstream’ of that. Somehow coolant is making its way into the intake system for both banks.
Might wanna check turbos. Not sure if these are cooled with coolant but many modern turbo cars have coolant in the turbos. Could also be oil from turbos. Obviously we can’t smell the smoke to know for sure which fluids burning😂. With no hydrocarbons in the reservoir it seems odd for it to be head, but you never know. Just an idea. Maybe it’ll help. Love the vids Mat keep it up.
Love watching this come together. I'm guessing you've already checked it, but I remember VTuned's 720S smoking a lot and it turned out that it was just overfilled with oil.
Had this on a Jeep I bought. Guy had swapped out the engine with one from a breaker and it did just this. I bought it as he had run out of money and considered it a knackered engine. What I couldn't work out, is how it tested fine for head gasket yet was quite obviously blowing out coolant. Yours reminded me of it. What had happened with the Jeep was his garage that fitted it had mistakenly put a vacuum breather and a coolant pipe the wrong around. That threw coolant into the turbo and doing what yours is doing. billowed white smoke, but head testing fine. Retrace all the pipes and make sure this hasn't happened in some part of this system. Nothing to lose but time. Good Luck - hoping it is this simple for you.
I really enjoy your videos because you don't always show when things go well. It's more realistic seeing all the process, not knowing if they going to make it through. Congrats. I'm sure you will find the way, you always do.
Genuinely my favourite channel on TH-cam at the moment. Highs and lows in every video. Laughs in every video. Even the sponsorship ads are actually incorporated into the video. Keep up the good work Mat, Mat’s dad and everyone else involved in this craziness.
Try bypassing the oil / coolant feeds to the turbos. If the charge cooler is dry, I’d guess whatever it is that’s making the smoke (looks like oil smoke to me) is getting into the exhaust through the turbines. Good luck, peace out and thanks for the awesome channel, don’t stop! 👍👍👍
I thought that too, but it’s very light colored and not to mention if it was oil smoke they would smell burnt oil and not be looking for misplaced water lines. Hopefully it’s not a cracked sleeve and just a gasket.
Well done for getting so much done! Honestly with all your other projects and galavanting around the world, I don't know where you find the time! But hats off to you and your Dad and the team. From the colour of that exhaust I'd say it's burning oil not water. Especially as it blew the oil cap off. I'd recommend you start with some compression checks. It could also be as simple as valve guides leaking, but either way that head will need to come off. Good luck mate.
I was amazed by the syspension beause that was my thesis in 1999. The whole idea was to do what citroen did in Xanthia without the need of a pump. We also built a 1:2 model of a car with dumpers connected that way. Instead of electrical valves we used manually adjusted flow control valves. We have also connected the front with the back so when you break and the car tries to lean forward the whole system tried to keep the car fully parallel to the ground giving extra stubility by pushing the rear wheels to the ground, so you have more grip. It is nice that some ideas are not left in some piece of paper!
Now I know why it’s always foggy in the UK 😂 i am still celebrating your face when you got it that the used suspension parts were more expensive than the new ones from McLaren😂😂 I really love your team, your channel and especially this car. Keepin Fingers crossed that you make it until X-Mas.
Hi Mat, i recall that either Vtuned or Freddy also had a lot of smoke, the first time they started their Mclaren after a rebuilt. I can't imagine that the headgasket will be blown because of a crash, i'am also thinking towards the Turbo's. On Idle, the smoke is not too bad, when you rev, those turbo's push a lot of air and smoke through the system is my guess. Keep up the good work, i love your video's and how you guys keep on laughing!
I have never and will never own any vehicle like the ones Mat rebuilds. I’d say I’m jealous but I had a brain aneurysm almost 14 years ago and haven’t driven since. I still love watching these videos because Mat and Tony are amazing together and they make what seems impossible, possible for every day guys. I can’t imagine tackling a job like this and you guys just do it and figure it out as you go along. Well done and such a positive attitude. Now if we can just teach Mat to say Us and the likes hahaha. Sorry Mat, just kidding.
MATT My Twin Turbo 335i DID THIS AFTER SITTING FOR 8 Months and not running at all. I ran the car for about 20 minutes (OUTSIDE) and let all the oil and fuel and water work it's way out of the turbos and exhaust. It billowed HUGE AMOUNTS OF WHITE SMOKE for about 15 minutes then started to clear out and slowly but surely it became clean and clear!!! Just let the car run for a while and wait and see if it clears up. It could be just fuel and water etc in the system needing to burn off!!! THAT WAS THREE YEARS AGO and now I have a 600 HP car that runs perfectly! No engine rebuild nothing!! Just let her run off!!!
I love how your dad absolutely cracks up laughing when a serious issue occurs. It really does lighten the mood although prob not for yourself ! Your face had that definite ..’oh ffs no way’ look about it this time. Fingers crossed it’s just something on the lines of turbo oil seals or some other oil drain issue through a turbo. Even then the fix could be a pricey addition to an already eyewateringly expensive rebuild. This is turning into my favourite build series so far. Good luck Mat.
Mat - "That's rough that".. Chris - "it's going in though" 🤣 Love how you lads just like to get the job done, no tip-toeing around or being overly gentle.
vacuum fillers are great yes but you might consider also getting a coolant pressure tester as well. use it first to test the system under full pressure. this makes it way easier to find leaks before adding any fluid. great job so far. your dad is a great person to have in the shop to help and break up the tension
I absolutely enjoy every video you guys do!!! It feels like I am right along there with you. I enjoy the great attitude you all have and the ability to have fun no matter what. Even if it costs money. LOL
What I love about thus channel is its something any one could do. Not because it's easy but because it's just hardwork and being smart with budget. How he does these could be applied to any project, yeah we all can't buy a crash McLaren but it could be a small car or a cheap property. Get it for a good price and work pit what it needs and find those things at the best price. Learn some skills and work hard. It's a simple process yet so many think they can't do it. When I watch these videos I don't see a youtuber with money buying an expensive car, I just see a bloke working has ass off long hours fixing a broken car. I reckon he should do something else other than a car as a challenge haha.
Great content as always Matt. I think the breakers should reimburse you for the shocks as a kind gesture. Would go for as all can see that here or even give them a shout-out. I know it's not gonna happen.
35 years ago my first car was a 1.3 L Astra, I remember giving it large one night and it ended up smoking like that, it ended up being the head gasket. Best of luck with this one, refreshing to see someone so positive for a change!
If you’re having a bad day, you only have to watch one of these videos to know it’s not all that bad. The attitude, positivity and enthusiasm are infectious. I love Wednesdays, upload day 🎉😊
I’m from Leicester too you’re probably the best thing that’s ever come out of Leicester. I love your videos so much. Keep up the good work and have a wonderful Christmas
Awesome video Mat! Not usually one to comment, but I've had a similar issue before, with a similar amount of smoke. Others have said Turbos here (which I think also could be a potential), I'd also check the PCV/CCV system as if they properly go, then they can throw that much oil into the intake system (at least it looks like maybe it's oil to me?)
Ive been watching the channel for some time and wondering what is the alcamy that keeps me coming back? I like cars but wouldnt call myself a petrol head. And the magic is that Matt, you're an extraordinary educator. You make the mundane interesting and the complicated simple. Also the editing is so professional. I suspect you could teach anything if you put your mind to it. Keep up the good work
Hiya Matt remember when you started the McLaren you had no water in system. If head Gasket has gone it wouldn’t run at temperature she would overheat. I think you must have a system on the engine that cools something down with water running through. So have you got a pipe wrong or is there a water inlet manifold or something not connected properly?? Remember your oil cooler was damaged and you replaced it water runs through that . How dose your thermostat housing work on the McLaren?? diagram on water system and water flow may help . Engine not bad in my opinion 🙏good look. And carry on with what you do best 👍
Matt. Check ur turbos could be leaking a bit of oil. Or check ur pcv/ccv system could be damaged and returning to much oil that’s being burnt in the system. I doubt this could be it but leave the car running and check coolant level if it goes down after a while if it running it’s probably cuz u have either a bad head gasket or a crack in the block. Really doubt full on the latter. Anywaves keep up the amazing content brother and don’t give up u got this. 😤😤
Love the fact the when things go wrong you and your dad laugh about it! It shows a humbleness and appreciation of the unique live you get to live. Never change! 👍
Here from Life of Palos . Always bragging about how AWESOME your content is and how fast your channel has grown. Been Subbed for like 6 months and you and your dad have been killing it. Much love and respect from little ole MAINE USA
Bro i wish i could be you! The amount of videos i have watched you work on cars and deal with the wiring systems you make it look easy! I wish you made classes to learn how to do things on cars! Great videos like always!
Need to check if that’s coolant get a borescope and look at the inlet ports. When we was developing the engine heads would crack and we would get coolant dribbling into the cylinders from the back side of the inlet valve
Tony's cheeky laugh when things don't look good as soon as it turns over..... priceless 😂 That is the laugh of an experienced tradesman who knows the job will take just that little bit longer now. I reckon there's oil pumping into the cylinders somewhere, possibly through a turbo. What ever the problem is...the lads will get to the bottom of it. I hope Mat gets his money back on the defective parts. Stay calm and have a cup of tea 🙂
The engine crankcase is being presurised, the oil filler cap popped off. With a dry sump the crankcase is usually running with a small vacuum with a tiny ventilation hole/pipe. If the outputs of the turbo are dry it must be coming from within, hopefully not head gasket. I am sure with emissions control regulations the ventilation of the crankcase/heads is complex. Before stripping the engine, try checking all of the ventilation pipes and make sure the turbos are not presurising the crankcase due to a pipe connected to the wrong place or a ventilation valve connected backwards.
Drain the oil start with 6.5 qts. Perform check oil level sequence using the cluster in service settings. Oil temp must be at operating temperature. Add little by little after each check level sequence until level says ok. Most likely overfilled with oil even the oil level slightly over it will cause the smoke. Good luck!

If you take a turbo off check in the exhaust prior to it, if there’s no oil in it then that’s your issue
Maybe check that all crankcase ventilation pipes and valves are on the right way around.
That can also explain why the oil filler cap flew off

Looks like the oil drains on the turbos might be kinked or not positioned correctly. You'll smoke like that at idle and free revving since the oil has no where to go and it just goes through the seals. Good luck!
This!!!! Also the oil gets into the turbos and creates a puddle over time which looks exactly like what’s happening here.

Than the smoke would be blue.
Now its white condensation/steam
Also intercooler is dry
That's not oil, that's water/coolant, oil smoke is blue.
Could still be turbos if their water cooled and a seals gone
Maybe vacume to crank case vacumum system or check valves

It starts easy. So I don't think it's Ll doom and gloom. I think you could need to recode everything...
Try scanning the OBD with your scanner.
Or a shot turbo
Don't give up Mat! The engine sounds good enough. Have you checked the crankcase ventilation system for blockages or nipped tubes?
The reason why it's not going into gear is probably because there is no doors connected so the car's computer thinks they are open so wont go into gear think I heard them say this on a dde video during there 720 rebuild.

Yea, actual faults can sometimes be something totally unrelated to the "problem". I had an ABS/ESP light on on my Peugeot a few years ago, and the dealer wanted to replace the ABS pump for £1,000, even though the ABS was working fine, so I ran away, quickly.
I eventually figured out that the problem was a stuck EGR. Basically the car didn't know the position of the EGR valve, so it couldn't calculate a torque value; which was needed for the ESP system to work. And the previous owner had blocked the EGR and deleted the parts of the code in the ECU responsible for EGR faults, so that the car wouldn't give any EGR faults.
It was annoying, but it was really satisfying to logically trace the fault and find the problem.
Your dad's enthusiasm is so contagious Matt even though you are going through problems on the build he keeps it 💯 I just love that he sees the light at the end of the tunnel
Discovered this channel a few weeks ago. Massive respect for the amount of technical knowledge and determination! Funny to see you laugh at all the smoke where I would be definately crying.
You have a lot to catch up. Watch them all from the start in order!
Its crazy how he makes it simple to fix a car😂
This one doesn’t seem very simple
Because it is easy to fix a car as long you have parts
@@ruioliveira9845 No you need alot of knowledge
@@sykolol2681 nah u just need youtube and some simple knowlage of how that works and you'll be good
@@milanum1565 isn't it ironic that you're trying to lecture others while not being able to spell the word knowledge
Matt you are a huge inspiration to us all and a major reason I finally started my TH-cam channel. Been here since the wrecked TT and have loved watching your growth so much. Bummed I didn't get to meet you at SEMA, but excited to keep watching your journey. Thanks for the inspiration 🙏🏻
The smoke looks like burning oil. This can happen with McLarens when they sit for a long time as the oil leaks into the turbos. Let it run for a bit and see if it starts to improve. Could save you from taking the engine out.
that smoke from the engine maybe disappointing right now but those things what makes others stop or give up but anyone who watching your channel are certain you gonna find a solution anyway and thats why your channel is truly great cause you guys never give up! :) Wish you all the best to find the solution this time as well!
They would know if the smoke was oil, because it would smell like burnt oil. The white exhaust smoke was almost certainly coolant.
The fact it was coming out both exhausts (ie both banks) indicates it’s not something affecting just one bank. It’s extremely unlikely for both turbos to fail in the same way, and also extremely unlikely for both head gaskets to fail.
So it must be something ‘upstream’ of that. Somehow coolant is making its way into the intake system for both banks.
Might wanna check turbos. Not sure if these are cooled with coolant but many modern turbo cars have coolant in the turbos. Could also be oil from turbos. Obviously we can’t smell the smoke to know for sure which fluids burning😂. With no hydrocarbons in the reservoir it seems odd for it to be head, but you never know. Just an idea. Maybe it’ll help. Love the vids Mat keep it up.
Oil would have smoked a different color. This is definitely coolant
Love watching this come together. I'm guessing you've already checked it, but I remember VTuned's 720S smoking a lot and it turned out that it was just overfilled with oil.
I’m feeling ya Matty
Check the turbos aren’t Very Bad first.
Work it out before pulling the motor
Love your work brother
I'm sure you'll get the engine sorted, but please have proper ventilation in your unit to allow the exhaust gases to escape!
Had this on a Jeep I bought. Guy had swapped out the engine with one from a breaker and it did just this. I bought it as he had run out of money and considered it a knackered engine. What I couldn't work out, is how it tested fine for head gasket yet was quite obviously blowing out coolant. Yours reminded me of it. What had happened with the Jeep was his garage that fitted it had mistakenly put a vacuum breather and a coolant pipe the wrong around. That threw coolant into the turbo and doing what yours is doing. billowed white smoke, but head testing fine. Retrace all the pipes and make sure this hasn't happened in some part of this system. Nothing to lose but time. Good Luck - hoping it is this simple for you.
Congratulations Mat for how you approach your work.. thanks to you I am having the strength and courage to publish all my videos. Thank you so much ❤️
The work ethic of Matt and his crew is insane!
I really enjoy your videos because you don't always show when things go well. It's more realistic seeing all the process, not knowing if they going to make it through. Congrats. I'm sure you will find the way, you always do.
Super inspiring. Makes me want to use my garage like a proper garage 🙏
Genuinely my favourite channel on TH-cam at the moment. Highs and lows in every video. Laughs in every video. Even the sponsorship ads are actually incorporated into the video. Keep up the good work Mat, Mat’s dad and everyone else involved in this craziness.
Yh other people do the sponsored ads in a different frame not like whilst doing the video. Very clever of mat
Try bypassing the oil / coolant feeds to the turbos. If the charge cooler is dry, I’d guess whatever it is that’s making the smoke (looks like oil smoke to me) is getting into the exhaust through the turbines. Good luck, peace out and thanks for the awesome channel, don’t stop! 👍👍👍
I thought that too, but it’s very light colored and not to mention if it was oil smoke they would smell burnt oil and not be looking for misplaced water lines. Hopefully it’s not a cracked sleeve and just a gasket.
Its definitely not oil that’s coolant its too dense to be oil
Both turbos would not fail at the same time. Smoke coming out of both banks - does it have a water heating loop in the intake manifold?
@@TheSharkLX unlikely for both heads to fail aswell its definitely a strange one
That smoke is too billowy and bright white to be anything but water. I’m afraid he’s gonna be pulling the engine and replacing head gaskets. 😢
You and your Dad still laugh and have so much fun even when the engine may be blown …..love the contagious laughter 👍🏻
Well done for getting so much done! Honestly with all your other projects and galavanting around the world, I don't know where you find the time! But hats off to you and your Dad and the team.
From the colour of that exhaust I'd say it's burning oil not water. Especially as it blew the oil cap off. I'd recommend you start with some compression checks. It could also be as simple as valve guides leaking, but either way that head will need to come off. Good luck mate.
To begin with there are two heads ! and valve guides leaking ? are you serieus ?
@@rudiknapen4867 No, but I might be serious. Plenty of smoke can come from the head (or heads) through the valve gear.
I honestly think it could be possible to get it done by Christmas, keep going mat 🙏🙏🙏
I was amazed by the syspension beause that was my thesis in 1999. The whole idea was to do what citroen did in Xanthia without the need of a pump. We also built a 1:2 model of a car with dumpers connected that way. Instead of electrical valves we used manually adjusted flow control valves. We have also connected the front with the back so when you break and the car tries to lean forward the whole system tried to keep the car fully parallel to the ground giving extra stubility by pushing the rear wheels to the ground, so you have more grip. It is nice that some ideas are not left in some piece of paper!
Now I know why it’s always foggy in the UK 😂 i am still celebrating your face when you got it that the used suspension parts were more expensive than the new ones from McLaren😂😂 I really love your team, your channel and especially this car. Keepin Fingers crossed that you make it until X-Mas.
Thank you for your honesty! Showing your mistakes and failures helps us to persevere in our projects even when we fail
Hi Mat, i recall that either Vtuned or Freddy also had a lot of smoke, the first time they started their Mclaren after a rebuilt. I can't imagine that the headgasket will be blown because of a crash, i'am also thinking towards the Turbo's. On Idle, the smoke is not too bad, when you rev, those turbo's push a lot of air and smoke through the system is my guess. Keep up the good work, i love your video's and how you guys keep on laughing!
I have never and will never own any vehicle like the ones Mat rebuilds. I’d say I’m jealous but I had a brain aneurysm almost 14 years ago and haven’t driven since. I still love watching these videos because Mat and Tony are amazing together and they make what seems impossible, possible for every day guys. I can’t imagine tackling a job like this and you guys just do it and figure it out as you go along. Well done and such a positive attitude. Now if we can just teach Mat to say Us and the likes hahaha. Sorry Mat, just kidding.
I love how your dad turns a "engine very bad" incident into a hilarious laughing moment!! 🤣
MATT My Twin Turbo 335i DID THIS AFTER SITTING FOR 8 Months and not running at all. I ran the car for about 20 minutes (OUTSIDE) and let all the oil and fuel and water work it's way out of the turbos and exhaust. It billowed HUGE AMOUNTS OF WHITE SMOKE for about 15 minutes then started to clear out and slowly but surely it became clean and clear!!! Just let the car run for a while and wait and see if it clears up. It could be just fuel and water etc in the system needing to burn off!!! THAT WAS THREE YEARS AGO and now I have a 600 HP car that runs perfectly! No engine rebuild nothing!! Just let her run off!!!
Mat should try rebuilding airplanes now. These rebuilds are too simple for him.😂😂😂
maybe one of them starships that space-x is launching. they recently just crashed one.
@@Jrakula10😂
Maybe he should modify trucks 😂
@@SilvaMoks no one should mod trucks...
Fantastic Work there Mat, I am body shop trained since 1989 . I haven't see that level of commitment for many years, keep up the good work.
Your getting there matt🥹. Don’t worry at all your fans are praying and will never leave your side 🥹🙏 hope to see new video soon
I love how your dad absolutely cracks up laughing when a serious issue occurs. It really does lighten the mood although prob not for yourself ! Your face had that definite ..’oh ffs no way’ look about it this time. Fingers crossed it’s just something on the lines of turbo oil seals or some other oil drain issue through a turbo. Even then the fix could be a pricey addition to an already eyewateringly expensive rebuild. This is turning into my favourite build series so far. Good luck Mat.
I know Mat will figure it out! You got this! Best wishes for simple fixes!
Mat - "That's rough that".. Chris - "it's going in though" 🤣 Love how you lads just like to get the job done, no tip-toeing around or being overly gentle.
Love how normal you guys are, you really keep it real! Good luck guys.
It blows my mind how you rebuild these cars, especially this one!🤯👌🏻 Love Big Tony’s laugh when the smoke starts billowing out of the exhaust!😂
Check the turbos before taking the engine out. Could be oil or water leaking into them causing that.
First time?
Glad you didn't give up on the tub, great work Mat 👌
Feel you pain Matt.And love the banter with you and your Dad, Good times always
Way to go Mat and team on getting it this far! Looks like another engine to take out and fix, you got this! 💪
vacuum fillers are great yes but you might consider also getting a coolant pressure tester as well. use it first to test the system under full pressure. this makes it way easier to find leaks before adding any fluid. great job so far. your dad is a great person to have in the shop to help and break up the tension
If i remember correct the same happenend for Vtuned after his 720 rebuild, he simply overfilled the oil.
I’m guessing turbo problems with that kind of smoke
Love it how Mat’s dad always laughs when something serious happens 🤣 hey, if you don’t laugh you’ll cry.
I think if it wasn’t for his dad he would’ve by the look on his face
Mat the brilliant way you film and narrate reassembly is one reason why you have grown this mega channel.
Matts dad is a bloody legend 🙌 makes me laugh in every vid, “daylight robbery!! Pants down “😂😂😂
I absolutely enjoy every video you guys do!!! It feels like I am right along there with you. I enjoy the great attitude you all have and the ability to have fun no matter what. Even if it costs money. LOL
What I love about thus channel is its something any one could do. Not because it's easy but because it's just hardwork and being smart with budget.
How he does these could be applied to any project, yeah we all can't buy a crash McLaren but it could be a small car or a cheap property. Get it for a good price and work pit what it needs and find those things at the best price. Learn some skills and work hard.
It's a simple process yet so many think they can't do it.
When I watch these videos I don't see a youtuber with money buying an expensive car, I just see a bloke working has ass off long hours fixing a broken car.
I reckon he should do something else other than a car as a challenge haha.
Great to see the car making great progress! Mat is the coolest Person alive! ❤
Great content as always Matt. I think the breakers should reimburse you for the shocks as a kind gesture. Would go for as all can see that here or even give them a shout-out. I know it's not gonna happen.
35 years ago my first car was a 1.3 L Astra, I remember giving it large one night and it ended up smoking like that, it ended up being the head gasket. Best of luck with this one, refreshing to see someone so positive for a change!
Matt definitely just saved someone’s job when he bought all them parts from the 720s 🤣
If you’re having a bad day, you only have to watch one of these videos to know it’s not all that bad.
The attitude, positivity and enthusiasm are infectious.
I love Wednesdays, upload day 🎉😊
I’m from Leicester too you’re probably the best thing that’s ever come out of Leicester. I love your videos so much. Keep up the good work and have a wonderful Christmas
Love the content lads, I'd certainly recommend checking the turbos first - they'll have a centre water jacket with seals, common to perish.
You'll get it worked out Mat! We have faith in you. Keep up the amazing content my man.
Awesome video Mat! Not usually one to comment, but I've had a similar issue before, with a similar amount of smoke. Others have said Turbos here (which I think also could be a potential), I'd also check the PCV/CCV system as if they properly go, then they can throw that much oil into the intake system (at least it looks like maybe it's oil to me?)
you will get through this mat.
Ive been watching the channel for some time and wondering what is the alcamy that keeps me coming back? I like cars but wouldnt call myself a petrol head. And the magic is that Matt, you're an extraordinary educator. You make the mundane interesting and the complicated simple. Also the editing is so professional. I suspect you could teach anything if you put your mind to it. Keep up the good work
Hiya Matt remember when you started the McLaren you had no water in system. If head Gasket has gone it wouldn’t run at temperature she would overheat. I think you must have a system on the engine that cools something down with water running through. So have you got a pipe wrong or is there a water inlet manifold or something not connected properly?? Remember your oil cooler was damaged and you replaced it water runs through that . How dose your thermostat housing work on the McLaren?? diagram on water system and water flow may help . Engine not bad in my opinion 🙏good look. And carry on with what you do best 👍
Matt. Check ur turbos could be leaking a bit of oil. Or check ur pcv/ccv system could be damaged and returning to much oil that’s being burnt in the system. I doubt this could be it but leave the car running and check coolant level if it goes down after a while if it running it’s probably cuz u have either a bad head gasket or a crack in the block. Really doubt full on the latter. Anywaves keep up the amazing content brother and don’t give up u got this. 😤😤
Love the fact the when things go wrong you and your dad laugh about it! It shows a humbleness and appreciation of the unique live you get to live. Never change! 👍
Here from Life of Palos . Always bragging about how AWESOME your content is and how fast your channel has grown. Been Subbed for like 6 months and you and your dad have been killing it. Much love and respect from little ole MAINE USA
Bro i wish i could be you! The amount of videos i have watched you work on cars and deal with the wiring systems you make it look easy! I wish you made classes to learn how to do things on cars! Great videos like always!
Need to check if that’s coolant get a borescope and look at the inlet ports. When we was developing the engine heads would crack and we would get coolant dribbling into the cylinders from the back side of the inlet valve
Tony's cheeky laugh when things don't look good as soon as it turns over..... priceless 😂 That is the laugh of an experienced tradesman who knows the job will take just that little bit longer now. I reckon there's oil pumping into the cylinders somewhere, possibly through a turbo. What ever the problem is...the lads will get to the bottom of it. I hope Mat gets his money back on the defective parts. Stay calm and have a cup of tea 🙂
Great work chaps, its coming on nicely. Refund needed on that bent shock, rip off breakers yard special.
Your Dad's laugh cracks me up, good or bad there is always a laugh, he is a legend matt, your lucky to have a dad like him mate
The engine crankcase is being presurised, the oil filler cap popped off. With a dry sump the crankcase is usually running with a small vacuum with a tiny ventilation hole/pipe. If the outputs of the turbo are dry it must be coming from within, hopefully not head gasket. I am sure with emissions control regulations the ventilation of the crankcase/heads is complex. Before stripping the engine, try checking all of the ventilation pipes and make sure the turbos are not presurising the crankcase due to a pipe connected to the wrong place or a ventilation valve connected backwards.
Drain the oil start with 6.5 qts. Perform check oil level sequence using the cluster in service settings. Oil temp must be at operating temperature. Add little by little after each check level sequence until level says ok. Most likely overfilled with oil even the oil level slightly over it will cause the smoke. Good luck!
hay, thanks for your videos ....great job keep working while doing your selling your product... you kept my interest.. usually i leave the video. so good job
I love your positivity Matt. Bloody inspirational. For mine this is my favourite uTube channel...by a long way..!! Looking forward to the next instalment.
Found you on YT and i am adicted to your work and how you manage to work yourself up..Respect dude.!!..Keep up the good work and nice video's.!
