I've bought old falcon sixes for $500 before. Let's do the maths. It normally costs say $100 per oil change (I do them myself) every 5000kms. So over 50000kms, that's $1000. If one $500 intech last 50000kms on one oil change, that's a lot cheaper.

Years ago, I was waiting for a phone call to start a new job. It came suddenly one afternoon. I started the next day as a mechanic with a hire boat company. A private boat had stopped the day before with a minor engine problem. The company boss had gone to take a look, had started the engine, a 4 cylinder diesel, had revved it up and 5 seconds later the oil pressure dropped to zero. I went on board and started the engine which ran smoothly but with still no oil pressure. I looked around the engine and discovered cracks on the right side of the block. When I took off the rocker cover, the rear two sets of tappets were completely loose. After taking the engine to bits, I discovered the camshaft had broken into 3 parts and a conrod had broken and shattered the block. All due to revving up a cold engine. Ended up fitting a new engine in the boat.

I think the era of car you would need to buy to have it last a lifetime is a long way in the past. The nearest I have is a Massey Ferguson 35x tractor of 1963 vintage that does a good days work and has decayed far less in the last 25 years than I have so I am fairly confident it will comfortably see me out. Spares, including full engine rebuild kits, injectors DPA pumps, tinwork, etc are all still available which is remarkable.
Can't agree. Late 80s and 90s car have ECUs that prove to be reliable and less hassle then carby shite, the body panels are rust treated well and overall they aren't that much different to a new car.
@@Low760 Well, there are plenty of 70 year old cars with carbs that are still running. It remains to be seen whether ECUs last that long. Spare 90s ECUs still available in 2060? Only time will tell.
There is an effect that used to be called acceptable quality. The idea is you only produce a quality that people will accept whether it be manufacturing service industry and even journalism the problem being is as the acceptable quality becomes the norm people will then start to accept a slightly lower quality and it ends up in a downward spiral of quality until you get to where we are now. Hopefully we are at or near the dregs of the barrel and people will start demanding better quality but the climb back up will be slower than the slide down
I've built my own computers since the 90's. I could never afford the prices computer shops charged so I got the components myself and squeezed the most out of them for as long as I could. Recently I quit smoking and had some car trouble so I thought I'd have a go at it to keep me busy. Quick self research found out I'll fucking die if use the supplied jack. Back to research and figured I could spend $300 on not dying and another $100 on making things easier, but it's capital expenditure so should be wife safe. Since then I've fixed a vacuum leak, changed various hoses, ignition coils and cables, sparks (and learned how to check gap), break pads, speed sensor (that was a c) and am about to do the cooling system. I'll try and make it my forever car just so I don't have to buy a new spyware on wheels. I still enjoy paying my Amiga 500 on weekends.
I sent you a message on Facebook asking for some more info on the Bluetti. I’ve been wondering how it’s going long term? Thanks for all of your content John.
I've had my FC ute since 1985 I got gifted from my grandfather only because he had his licence taken from him for being too old to drive I look after that old ute batter than my self I'm pretty sure that old FC will last longer than me as long as nobody steals it or run's into me
@@rocketgg3169although your forever comment is technically correct the Original Posters comment still stands. Forever car is normally understood to be a car that can outlast your entire driving career. That ute is working it's way through a 3rd generation owners driving career. Ironic we have to look to vehicles seventy years from the past to achieve this and modern cars are flat out surviving thier warranty period
Your comments about knock are pretty good really. Maximum cylinder pressure doesn't happen at TDC, it's more like 14-18 ATDC, I figured it would be 90 ATDC because of the lever arm, but that would mean that the piston would need to be directly above the crank throw. But the crank/rod angle wouldn't be right for maximum torque since the rod will be at it's maximum angle instead of straight up. So 14-18 ATDC is the target for maximum cylinder pressure. The ignition timing for maximum power is after the point of knock, but it will also destroy the piston, so the OPTIMAL timing is bouncing off knock sensor as you describe. Maximum power is temporary, optimal power is optimal.
Well, manufacturers recommend oil changes at half the recommended intervals for stop start, towing, high speed driving etc. Basically unless you drive at 80kmh for 40km each trip, the servicing is too far apart.
The piston stops twice per crankshaft revolution before reversing its direction of travel. The piston accelerates from stationery to maximum speed mid-stroke then decelerates to stationary. An engine reciprocates, a motor rotates.
I have three cars over 60 years old. Only one never stopped being used until i replaced the motor with a more powerful one. My other cars are 35+ years old, and both have original motors even with modifications. My daily driver is a v8 vf Holden and i will be able to keep fixing it for decades to come based on engine management systems that are already over 30 and still going. Plus they only options now besides a mazda6 wagon are shitbox dual cabs and suvs.
John could you find some time in your inimitable way to enlighten some on MZ and German missile scientist Walter Kaaden made significant contributions to the development of two-stroke engines, including their resonant expansion-chamber exhaust systems.
Despite the fact that he did not open with the phrase "It's not my fault" , that article screams "written by a millennial who has extensively researched the topic on Face Book .
It's easy, just follow the "Severe Service" service schedule. The normal one is intended to let the maker publish low maintenance figures and hopefully get your car through the warranty period.
When I was 13 I attempted to make Mercury II Fulminate in my Parents Bathroom. I had a plastic sheet taped to the exhaust fan draped over the boiling Nitric Acid and Mercury. I'm thinking of how my parents must have felt raising me up from childhood. I feel sorry for them. I had an obsessive interest in Chemistry and I was kind of a cleverly dangerous kid. A week later I burned my hand with combusting Phosphorous. Wow. Didn't slow me down. I had some experiments with Chloroform that were waiting to be run.
engine knock usually doesn't happen before spark happens. It's about when spark happens and it shakes whole mixture with pressure and movement, fuel air mix finds kinda hot part like exhaust valve and starts burning at multiple places and whole burning process happens faster than should be. If full knock detonation happens kinda early in compression engine is kinda 100 kg waste metal
Hey John, love your work. I'm off topic, but thought it important enough to inform you of what recently dropped on IOTP (John Adams & Martin North's YT channel). '7 Days to stop 1984' quite dire IMO & keen to see your take on it.
Good on you John for calling these bullshitters out, as someone needs to! And I do trust that if and when you know Daisy Duke is coming to town you'll let us all know. 🤣
using what you said earlier in the video, roughly the ignition is advanced to a set amount to generate maximum power, if that's correct, preignition, knocking, detonation, whatever, won't generate maximum power aka lose performance, even in an old carby distributor engine.
Detonation is when the combustion flame front exceeds the speed of sound. Instead of a burn that heats the combustion chamber evenly, it literally explodes and sends a shock wave to the top of the piston. It doesn’t matter where the piston is. It will bash everything to death if it happens often. Preignition is when the ignition happens so that peak pressure occurs before top dead centre and tries to make the engine run backwards. That would be a different kind of wrong
@@theairstig9164 i d;sn't think that's the best definition of preignition, but I always thought knocking was caused by preignition, but maybe you can get a knock from ignition caused by the spark of the spark plug.
I've run diesels for 45 years . Someone stole a David Brown crawler from the site and I assume left the throttle wide open. Because when I found it next to the road. A piston had gone through the side of the engine and embedded itself in the frame.. The machine was scrapped.
I have this RON rating argument with so many fools that believe 98 is a literal premium and everything below that, especially E10 is rubbish . Even the dude taking cars on 2GB makes these stupid statements 🤷🏼♂️🤷🏼♂️
Only really an issue if you have a car with a GPF (gasoline particulate filter). They require low sulphur fuel, which is only guaranteed with 95 and 98 RON fuels in Australia. 91 and E10 can be up to 150ppm sulphur which can severely reduce the life of the GPF.
When you see the seemingly endless parade of cars with oil in the windscreen washer bottle, water lines hooked up to automatic transmission breathers and many many more hilarious things on the 'Just Rolled In' youtube channel, perhaps average person of the street doing maintenance on their car isn't such a good idea.
There are likely over a million cars older than 75 years registered in America, though probably not daily driven. There are so many model-T cars that every single part of the car is available today. You could build a brand new Model T from parts. Putting aside the "forever" in forever, if you were willing to spend the money and be stuck with a severely out of date car, you could buy a new car when you're 18 and keep it as your only car till the day you die.
To be a tad pedantic. 99% of detonation events happen after combustion is initiated by the spark. Pre-ignition is combustion starting before the spark. They are usually two separate mechanisms. Both are symptoms of other underlaying issues.
To add more tech bollocks; Detonation does not cause overheating, the overheating causes the detonation. This can be seen by EGTs dropping when detonation occurs. The energy that would normally progressively heat and expand the gases is instead converted into noise and mechanical violence, any expansion occuring too quickly, and at the wrong crank angle, to be harnessed. That said, best power requires low level detonation to be occuring, else combustion is not making the most of the available energy.
Not pedantic at all. It's rare that John gets something wrong, but in this case he did and your correction is warranted. To be fair, he did somewhat correct himself later in the video.
Choose your engine carefully section states that your "petrol engine has to rev to 6500 rpm or higher." Does it really? I mean, REALLY! I always valve bounce down to the corner shop and do keep it in second gear at highway speeds just to keep the J2 Bedford where Tyler Bedford insists it has to be.
@AutoExpertJC You want to do a video on the Toyota shame that is their warranty department regarding GR yarises spontaneously combusting. They even reveal that they are mining on your personal driving metrics too! Easy to sell on to insurance companies as always 🤣
Just buy yourself an old corolla, camry, hilux or 100 series, whatever fits your needs and change the oil every 10k. minimal depreciation and just basic maintenance you can do yourself.
You might not be able to make your car last forever but there are a surprising number of Ford Model T around the world over 100 years old that still run.
I use good ole clear waxoil on my cars and got 25 years of use out of my last diesel car which totted up nearly 300 thousand miles with regular oil changes. I expect my new 3 year old car to last just as long. Im also rescuing an old classic before all you can buy is an EV.
You work at the local tip. You take goods from the retailer and you send those goods to the rubbish tip. How much that your parents spent all their/your inheritance on have you still got. Either it's at the tip or will be shortly
By coincidence I watched a repeat episode of Mythbusters. They were testing mercury fulminate and their results agreed with your statement that the "Breaking Bad" explosive effect of Hg(CNO)2 was greatly exaggerated.
A crystal that big would be very dangerous, and the rest of it in the bag would have almost certainly killed them both. But it was pretty cool in a drama...
Some quick math here: E10 is 10% (1 out of 10) ethanol, so if ethanol had a heat energy content of 0 btu it would reduce power by 10%, requiring you to add fuel to compensate -- ergo lower milage (assuming the load doesn't change). The problem with your concern is that ethanol does indeed contain somewhat more than 0 btu when it amounts to 10% of the mixture and it is added mostly for other reasons (not gonna argue over whether those reasons are worthwhile, but i'll note that I run E15 in my direct injection engine in an attempt to keep the intake valve clean when I don't run "Top Tier" fuel with that additive mix of cleaners).
Dwell was the amount of time the points were closed for. Smaller points gap meant a greater dwell angle which enabled the coil to charge for longer in order to produce a stronger spark. Widening the points gap reduces dwell but it does advance ignition timing due to the points being open a fraction sooner. That's more a side effect than a timing adjustment.
@@jamesforge8107 Yep; ignition timing was adjusted by turning the distributor; hilarious how people with a little knowledge get it wrong with such confidence..
Is the piston slowing down on the way back up after ignition? What about the other piston that is in the ignition downwards phase? Doesn't that drive all the other cylinders? Surely the crankshaft would not allow any cylinder to travel at a different speed to the other cylinders?
@@ehb403 not confused, rotation converted to reciprocal, in a cycloid motion, pistons move at their slowest at the top and at the bottom, fastest when the big end is at 90°. I'm saying pistons do not come back up slower after ignition, all pistons attached to the crank, move at the same rate (varying in velocity, obviously, due to the degree of crank rotation), I think we are agreeing with each other here. A piston cannot decide it will move back up at a slower rate because its power stroke has been spent. Which is what our dude seems to say.
@@Zebedeedoo ahhh, it's the geometry then. The angle (crank journal/ rod) is larger at the top of the crank movement than at the bottom, pulling the piston downward faster than it moves at the bottom (drawing it out might help).
@@ehb403 not sure what you mean, but a piston moves at its fastest while the con rod is at 90° to the direction of movement the piston is travelling in, and slowest as that very angle decreases til it stops, and reverses direction. I'm getting a bit fed up explaining this to people who feel the need to explain to me.
The problem with forever cars is you don't get the opportunity for full technical advancements. Unless we are happy that it won't be possible to improve safety and crash structures, I wouldn't entertain a forever car.
The good old days of leaded fuel, no valve recession and knock was rare. I maintained a lead blender in a refinery back in the late seventies to early eighties injecting Tel and TML into the motor spirit storage tanks. When we discontinued using leaded fuel we still had inventory of TEL and TML we sold it to India! The storage tanks were demolished and the steel was incinerated to remove all traces, highly toxic. When the lab technicians at GM first made it they turned black and died, back in 1925. We dumped God knows how much into the atmosphere and we breathed it but our engines loved it. I know what TEL smells like, don't ask me how I know. .
The good old days of leaded fuel, no valve recession and knock was rare. I seriously have to disagree with that statement. I had to do hundreds headjobs because of valve recession back in the day.
So did Drive actually find a 'forever' car. I mean, they've been around for about 130-140 years and while that's short of forever, it's longer that Zeedoube's forever existence. And do you have to be simple to simply drive the car into the next millennium ?
changing the oil is cheaper than changing the engine and changing the engine is usually cheaper than buying a new shitbox.
... and buying a new shitbox is usually cheaper than buying one without an engine and oil change needs, i.e. EV.

I think the era of car you would need to buy to have it last a lifetime is a long way in the past. The nearest I have is a Massey Ferguson 35x tractor of 1963 vintage that does a good days work and has decayed far less in the last 25 years than I have so I am fairly confident it will comfortably see me out. Spares, including full engine rebuild kits, injectors DPA pumps, tinwork, etc are all still available which is remarkable.
Can't agree. Late 80s and 90s car have ECUs that prove to be reliable and less hassle then carby shite, the body panels are rust treated well and overall they aren't that much different to a new car.
@@Low760 Well, there are plenty of 70 year old cars with carbs that are still running. It remains to be seen whether ECUs last that long. Spare 90s ECUs still available in 2060? Only time will tell.
There is an effect that used to be called acceptable quality. The idea is you only produce a quality that people will accept whether it be manufacturing service industry and even journalism the problem being is as the acceptable quality becomes the norm people will then start to accept a slightly lower quality and it ends up in a downward spiral of quality until you get to where we are now. Hopefully we are at or near the dregs of the barrel and people will start demanding better quality but the climb back up will be slower than the slide down
We've been downhill since the 60s but ok
I've built my own computers since the 90's. I could never afford the prices computer shops charged so I got the components myself and squeezed the most out of them for as long as I could. Recently I quit smoking and had some car trouble so I thought I'd have a go at it to keep me busy. Quick self research found out I'll fucking die if use the supplied jack. Back to research and figured I could spend $300 on not dying and another $100 on making things easier, but it's capital expenditure so should be wife safe. Since then I've fixed a vacuum leak, changed various hoses, ignition coils and cables, sparks (and learned how to check gap), break pads, speed sensor (that was a c) and am about to do the cooling system. I'll try and make it my forever car just so I don't have to buy a new spyware on wheels.
I still enjoy paying my Amiga 500 on weekends.
@@HaMMeR_Oz not a 486?
Now you just need to learn the difference between breaks and brakes, mate
I cannot wait for the future but I can wait for the future😊
I sent you a message on Facebook asking for some more info on the Bluetti.
I’ve been wondering how it’s going long term?
Thanks for all of your content John.
I've had my FC ute since 1985 I got gifted from my grandfather only because he had his licence taken from him for being too old to drive I look after that old ute batter than my self I'm pretty sure that old FC will last longer than me as long as nobody steals it or run's into me
Forever=Forever
Forever is a shite tonne longer than you will be around
(Shite tonne longer = technical term)
@@rocketgg3169although your forever comment is technically correct the Original Posters comment still stands. Forever car is normally understood to be a car that can outlast your entire driving career. That ute is working it's way through a 3rd generation owners driving career. Ironic we have to look to vehicles seventy years from the past to achieve this and modern cars are flat out surviving thier warranty period
Your comments about knock are pretty good really. Maximum cylinder pressure doesn't happen at TDC, it's more like 14-18 ATDC, I figured it would be 90 ATDC because of the lever arm, but that would mean that the piston would need to be directly above the crank throw. But the crank/rod angle wouldn't be right for maximum torque since the rod will be at it's maximum angle instead of straight up. So 14-18 ATDC is the target for maximum cylinder pressure.
The ignition timing for maximum power is after the point of knock, but it will also destroy the piston, so the OPTIMAL timing is bouncing off knock sensor as you describe. Maximum power is temporary, optimal power is optimal.
Saily saw a very hot spot in the add. I'm sold.😂
Best intro ever 🤗
Common sense - thank you John!
Well, manufacturers recommend oil changes at half the recommended intervals for stop start, towing, high speed driving etc. Basically unless you drive at 80kmh for 40km each trip, the servicing is too far apart.
The piston stops twice per crankshaft revolution before reversing its direction of travel. The piston accelerates from stationery to maximum speed mid-stroke then decelerates to stationary.
An engine reciprocates, a motor rotates.
Good content from you Very advertorial content from Drive.
Going off Early and Detonating.. Story of my life really 😀
I have three cars over 60 years old. Only one never stopped being used until i replaced the motor with a more powerful one. My other cars are 35+ years old, and both have original motors even with modifications. My daily driver is a v8 vf Holden and i will be able to keep fixing it for decades to come based on engine management systems that are already over 30 and still going. Plus they only options now besides a mazda6 wagon are shitbox dual cabs and suvs.
John could you find some time in your inimitable way to enlighten some on
MZ and German missile scientist Walter Kaaden made significant contributions to the development of two-stroke engines, including their resonant expansion-chamber exhaust systems.
Despite the fact that he did not open with the phrase "It's not my fault" , that article screams "written by a millennial who has extensively researched the topic on Face Book .
love your learnin stuff
Knock, knock..."who's there?"......"Zane with the stupid tie"....
I wish my old VK Commodore would've lasted forever. I liked your PRO TIP, very funny.
🙂I have no comment to make or contribute but, AEJC version is a very convincing point view? and one I'm going with 🙂
It's easy, just follow the "Severe Service" service schedule. The normal one is intended to let the maker publish low maintenance figures and hopefully get your car through the warranty period.
Did you get all that Max? "Yes chief, except the bit after listen closely..."
When I was 13 I attempted to make Mercury II Fulminate in my Parents Bathroom. I had a plastic sheet taped to the exhaust fan draped over the boiling Nitric Acid and Mercury.
I'm thinking of how my parents must have felt raising me up from childhood. I feel sorry for them. I had an obsessive interest in Chemistry and I was kind of a cleverly dangerous kid.
A week later I burned my hand with combusting Phosphorous. Wow. Didn't slow me down. I had some experiments with Chloroform that were waiting to be run.
Gracias loco.
engine knock usually doesn't happen before spark happens. It's about when spark happens and it shakes whole mixture with pressure and movement, fuel air mix finds kinda hot part like exhaust valve and starts burning at multiple places and whole burning process happens faster than should be.
If full knock detonation happens kinda early in compression engine is kinda 100 kg waste metal
Yes , that's right ...
Hey John, love your work. I'm off topic, but thought it important enough to inform you of what recently dropped on IOTP (John Adams & Martin North's YT channel). '7 Days to stop 1984' quite dire IMO & keen to see your take on it.
Good on you John for calling these bullshitters out, as someone needs to! And I do trust that if and when you know Daisy Duke is coming to town you'll let us all know. 🤣
I'm certainly looking forward to it...
John, have you seen Catherine Bach lately? She's more of a teepee dismantler these days...
using what you said earlier in the video, roughly the ignition is advanced to a set amount to generate maximum power, if that's correct, preignition, knocking, detonation, whatever, won't generate maximum power aka lose performance, even in an old carby distributor engine.
Detonation is when the combustion flame front exceeds the speed of sound. Instead of a burn that heats the combustion chamber evenly, it literally explodes and sends a shock wave to the top of the piston. It doesn’t matter where the piston is. It will bash everything to death if it happens often.
Preignition is when the ignition happens so that peak pressure occurs before top dead centre and tries to make the engine run backwards. That would be a different kind of wrong
@@theairstig9164 i d;sn't think that's the best definition of preignition, but I always thought knocking was caused by preignition, but maybe you can get a knock from ignition caused by the spark of the spark plug.
Did somebody say hotties?
YESSSSSSSS!
Sometimes your personal biases cloud your ability to be unbiased.
I've run diesels for 45 years . Someone stole a David Brown crawler from the site and I assume left the throttle wide open. Because when I found it next to the road. A piston had gone through the side of the engine and embedded itself in the frame.. The machine was scrapped.
I have this RON rating argument with so many fools that believe 98 is a literal premium and everything below that, especially E10 is rubbish .
Even the dude taking cars on 2GB makes these stupid statements 🤷🏼♂️🤷🏼♂️
Only really an issue if you have a car with a GPF (gasoline particulate filter). They require low sulphur fuel, which is only guaranteed with 95 and 98 RON fuels in Australia. 91 and E10 can be up to 150ppm sulphur which can severely reduce the life of the GPF.
Yes!!!
When you see the seemingly endless parade of cars with oil in the windscreen washer bottle, water lines hooked up to automatic transmission breathers and many many more hilarious things on the 'Just Rolled In' youtube channel, perhaps average person of the street doing maintenance on their car isn't such a good idea.
Spray foam works wonders.
There are likely over a million cars older than 75 years registered in America, though probably not daily driven. There are so many model-T cars that every single part of the car is available today. You could build a brand new Model T from parts.
Putting aside the "forever" in forever, if you were willing to spend the money and be stuck with a severely out of date car, you could buy a new car when you're 18 and keep it as your only car till the day you die.
I've still got a Holden Commodore that turns over, for anyone old enough to remember those bad boys
I don't buy E10 but it's cheaper at the pump if that's what matters,not that it needs to be that way either.
9:02 Doug Mulray: god indeed. And a nice coincidence - I was listening to his album _Nice Legs Shame About The Fez_ just last week. 👍
To be a tad pedantic.
99% of detonation events happen after combustion is initiated by the spark.
Pre-ignition is combustion starting before the spark.
They are usually two separate mechanisms.
Both are symptoms of other underlaying issues.
To add more tech bollocks;
Detonation does not cause overheating, the overheating causes the detonation.
This can be seen by EGTs dropping when detonation occurs. The energy that would normally progressively heat and expand the gases is instead converted into noise and mechanical violence, any expansion occuring too quickly, and at the wrong crank angle, to be harnessed.
That said, best power requires low level detonation to be occuring, else combustion is not making the most of the available energy.
Not pedantic at all. It's rare that John gets something wrong, but in this case he did and your correction is warranted. To be fair, he did somewhat correct himself later in the video.
Choose your engine carefully section states that your "petrol engine has to rev to 6500 rpm or higher." Does it really? I mean, REALLY! I always valve bounce down to the corner shop and do keep it in second gear at highway speeds just to keep the J2 Bedford where Tyler Bedford insists it has to be.
@AutoExpertJC You want to do a video on the Toyota shame that is their warranty department regarding GR yarises spontaneously combusting. They even reveal that they are mining on your personal driving metrics too! Easy to sell on to insurance companies as always 🤣
Just buy yourself an old corolla, camry, hilux or 100 series, whatever fits your needs and change the oil every 10k. minimal depreciation and just basic maintenance you can do yourself.
2001 Toyota HiLux Twincab, 550,000 kms and still going (I probably should not have said that !)
I remember the answer to this one its.. "Keep the oil pressure up all the time even when the engine is off"...
Have I been told lies about squeeze, suck bang blow???? JOHN!
PS you want peak cylinder pressure after TDC...
Great talk ok. We drive complex machines.
My 1992 F150 351 4x4 will last with me for my forever, that pull 4500kg comfortably
Incipient. $5 dollar word right there. I like Incipient Skid. When your tires start to sing around a curve letting you know it's time to ease up...
Don't forget that 91 octane has high sulfer content and that's why i don't use it.
NOT A SCAM - My car has lasted Forever. Product Works
You might not be able to make your car last forever but there are a surprising number of Ford Model T around the world over 100 years old that still run.
I carefully choose my engine every week. Thanks for that gem, drive.
But drive forgot to add: "Do not defecate inside your car".
I like cars
I use good ole clear waxoil on my cars and got 25 years of use out of my last diesel car which totted up nearly 300 thousand miles with regular oil changes.
I expect my new 3 year old car to last just as long. Im also rescuing an old classic before all you can buy is an EV.
I wasn't going to comment from the darkish place where I was at until you hated down on the universe, that did me cold. Cheers to you.
I love the universe. God's code could do with a tweak.
I’ve managed to put a fist size hole in the side of a Ford 4.1 litre straight six when two pistons decided to exit the side of the block.
You work at the local tip. You take goods from the retailer and you send those goods to the rubbish tip. How much that your parents spent all their/your inheritance on have you still got. Either it's at the tip or will be shortly
Slow speed combustion is also what is required in a gun chamber . .
By coincidence I watched a repeat episode of Mythbusters. They were testing mercury fulminate and their results agreed with your statement that the "Breaking Bad" explosive effect of Hg(CNO)2 was greatly exaggerated.
A crystal that big would be very dangerous, and the rest of it in the bag would have almost certainly killed them both. But it was pretty cool in a drama...
My JE Camira is still going.
In the US E10 is a legal way to dope fuels to reduce mileage...
Some quick math here: E10 is 10% (1 out of 10) ethanol, so if ethanol had a heat energy content of 0 btu it would reduce power by 10%, requiring you to add fuel to compensate -- ergo lower milage (assuming the load doesn't change). The problem with your concern is that ethanol does indeed contain somewhat more than 0 btu when it amounts to 10% of the mixture and it is added mostly for other reasons (not gonna argue over whether those reasons are worthwhile, but i'll note that I run E15 in my direct injection engine in an attempt to keep the intake valve clean when I don't run "Top Tier" fuel with that additive mix of cleaners).
In my past, pre-ignition/ knock was known as "pinking". Ignition advance was known as "dwell angle".
Dwell was the amount of time the points were closed for. Smaller points gap meant a greater dwell angle which enabled the coil to charge for longer in order to produce a stronger spark.
Widening the points gap reduces dwell but it does advance ignition timing due to the points being open a fraction sooner. That's more a side effect than a timing adjustment.
@@jamesforge8107 Yep; ignition timing was adjusted by turning the distributor; hilarious how people with a little knowledge get it wrong with such confidence..
Having a degree in thermodynamic well done John. Their word was just BS
Your giving me nightmares JC .......lolololol
Water and oil!
The only way to have a literal 'forever car' is to replace *every* part of the car, making it the car equivalent of the Ship of Thesus... :)
I agree with the first comment
Checking in from 1995 diesel LandCruiser land.
Aircon is really cold.
Abs and cruise control is still good.
Hoo roo.
Is the piston slowing down on the way back up after ignition?
What about the other piston that is in the ignition downwards phase? Doesn't that drive all the other cylinders? Surely the crankshaft would not allow any cylinder to travel at a different speed to the other cylinders?
Not only does it, it requires it. You're confusing linear velocity with rotational velocity.
@@ehb403 not confused, rotation converted to reciprocal, in a cycloid motion, pistons move at their slowest at the top and at the bottom, fastest when the big end is at 90°. I'm saying pistons do not come back up slower after ignition, all pistons attached to the crank, move at the same rate (varying in velocity, obviously, due to the degree of crank rotation), I think we are agreeing with each other here. A piston cannot decide it will move back up at a slower rate because its power stroke has been spent. Which is what our dude seems to say.
@@Zebedeedoo ahhh, it's the geometry then. The angle (crank journal/ rod) is larger at the top of the crank movement than at the bottom, pulling the piston downward faster than it moves at the bottom (drawing it out might help).
@@ehb403 not sure what you mean, but a piston moves at its fastest while the con rod is at 90° to the direction of movement the piston is travelling in, and slowest as that very angle decreases til it stops, and reverses direction. I'm getting a bit fed up explaining this to people who feel the need to explain to me.
The problem with forever cars is you don't get the opportunity for full technical advancements.
Unless we are happy that it won't be possible to improve safety and crash structures, I wouldn't entertain a forever car.
Nice gay t-shirt John!@!
From dream-world?
The good old days of leaded fuel, no valve recession and knock was rare.
I maintained a lead blender in a refinery back in the late seventies to early eighties injecting Tel and TML into the motor spirit storage tanks.
When we discontinued using leaded fuel we still had inventory of TEL and TML we sold it to India!
The storage tanks were demolished and the steel was incinerated to remove all traces, highly toxic.
When the lab technicians at GM first made it they turned black and died, back in 1925.
We dumped God knows how much into the atmosphere and we breathed it but our engines loved it.
I know what TEL smells like, don't ask me how I know.
.
The good old days of leaded fuel, no valve recession and knock was rare.
I seriously have to disagree with that statement.
I had to do hundreds headjobs because of valve recession back in the day.
They maybe we're using standard instead of super leaded fuel to save money.
So did Drive actually find a 'forever' car. I mean, they've been around for about 130-140 years and while that's short of forever, it's longer that Zeedoube's forever existence. And do you have to be simple to simply drive the car into the next millennium ?
The easiest way to make your car outlast you would be to take up a handful of extreme sports.
Worked at super Retail Group brendail and was verbally asulted and accused of doing the wrong thing on day's I wernt even at work
Still beat most everything off the line 😮
