5:50 ... That much carbon comes from low rpms (you know this, I get it).... :) Fuel/ oil comes into the bottom of the engine, and the oil will build up if you don't run the engine at high enough RPMs.. so a good way to greatly reduce this from happening is to periodically high rev the engine and hold it for a few seconds.... this will suck all that extra oil out of the bottom end and blow it out the exhaust... especially if it is smoking; that is telling you that there is too much oil in the bottom...

Very true. Back in the day I used a similar principle to 'de-coke' car engines without pulling them apart. I had an after-market windscreen washer reservoir / pump with a remote switch that I'd sit in the passenger footwell. Then I'd run a tube to the carby inlet and, with the engine under as much load as possible (either a heavy trailer hooked up or going up a steep hill) I'd squirt hot water into the inlet. Do that several times over a couple hours.... It seemed to work on the old side-valve engines I used it on.

two smoke engines burn oil , oil is carbon , maybe you are adding too much oil to the fuel , maybe you are running ritch , maybe definately squirting a drop or four of water into the cabr with the engine running will clean up some carbon ( works on four smokes anyway )
As a two-cycle mechanic, let me help you out here. The deposits on your piston are about right. Two-cycle combustion is inefficient and filthy. So, don't be concerned too much. Abrasives, the green Scotts bright pad is not only abrasive but can leave small fibers that can cause damage. Most of automotive has restricted its use when the engine is still in the car. Spark plugs, the gap opens up due to the high temperature on a two-cycle engine. Once a plug has seen some use and the gap has opened up, replace the plug. Keep your day job. I will look forward to two seeing you back at the machine shop.
I'm just used to being "that guy" explaining the grease monkey stuff to the guy with the dumb look on his face after it breaks. Looks like Tony has that under control, this time. I guess I'll just stand here with a dumb look on my face 😆
Thanks for the great watch. Been a viewer for several years. It's awesome to hear motor stuff from someone with a great sense of humor on the topic. Seems like most actual motorheads take it too serious sometimes. 10 out of 10. Hope to see some more wrenches poking engines from time to time.
Oh, Ya! How about a colab!! Adam can make the crank and Big Clive can make the coil. Fran could probably whip up a spark plug and Mustie1 will say, "Why? I can get engines already made, all day long, for free! And they will RUN!" ;-)
I don’t watch these videos for the machining. I watch them because your comedy is amazing. The machining is just a bonus, and stuff like this is even better.
I loved it! Keep more videos coming!! The appeal of your channel is not necessarily machining, it’s what you bring to any content that keeps us dying for the next one. Thank you Tony! Nice work!
Greecemonkey here! An easy way to diagnose a head gasket failure is smelling the coolant. If it smells like exhaust, you're in for it. Always love the videos! Cheers :)
Ok, here we go... Time to bust a myth. Many people will argue that a high flow water pump is counterproductive to efficient cooling because the coolant spends less time in contact with the hot engine parts and the cool radiator parts, and thereby must be less effective at transferring heat. The opposite is true and here's why: the speed with which heat will transfer from one material to another is directly proportional to the difference in temperature between the two materials. The greater the temperature difference, the faster the heat transfer. Therefore, the more time the coolant spends in any one place, the less efficient the heat transfer becomes. The only exception to this is if the pump is working so hard that cold side hoses collapse or cavitation occurs, both of which limit the coolant's ability to transfer heat. So, generally speaking, more flow and more pressure = better cooling.
Hmmmmm... Cooling system performance, design, analysis (and efficiency) are quite a complex set of related topics… Owing to the nonlinear, multi-variable nature of the physical behaviors involved, these topics defy most simple assumptions as well as simple attempts at optimization. BUT, AS A FIRST ORDER EFFECT, analysis and testing show that for induced-flow-liquid-cooling-systems (i.e. not thermosyphon systems), the benefit in performance (not efficiency) of increasing flow rate is most closely tied to the increase in vaporization temperature of the working fluid (i.e. boiling point) due to increased pressure. Because the heat capacity of vapor is poor, effective cooling with a liquid requires that it stay liquid. Increasing the flow has the potential to increase the fluid pressure at the hottest locations preventing localized vaporization (i.e. cavitation) and thereby might benefit localized cooling where it is most needed (i.e. create better cooling system performance). That said, increasing the local pressure of a working fluid by increasing the flow rate (as opposed to increasing the overall system operating pressure) means doing more work on the working fluid. More work means more heat. More heat means higher working temperatures… It’s a pretty vicious circle where small improvements are hard won. As for cooling system efficiency; that is a completely different beast. My advice? Stay well clear of using the terms “cooling system” and “efficiency” in the same V-blog comment. Cheers!
I had to read that a few times to grasp that, and it makes sense. The concept of high versus low flow rate is something I've encountered, but never examined... mostly because everything I owned that needed cooling seemed to be working fine without my coming with a headful notions about modifying it.
That was a really good video! I specifically appreciated how you make it seem these tasks are within the capability of someone who is not a mechanic. It feels like people have been hugely dissuaded from working on their own motorcars and bikes.
"what's happening is a motor is driving a shaft and moving the cylinder and that spins your laundry in the hot water and soap, here let me show you on the lathe." And a joke about using motor oil as laundry soap.
Not only did you help inspire me when I first started machine, but I have two 1969-1970 Honda Trail 90s I’ve rebuilt and got running (literally second one last night) so this video was spectacular. Anyone who doesn’t like turning wrenches is weird so please make more. Thanks again for everything Uncle Tony
I really enjoyed this, I love your machining stuff but I thoroughly enjoy you explaining other things. You go about things so calmly it's hypnotic and I feel like I learn stuff 😅
"Resist the urge to use any abrasives on this thing" while shoving and washing aluminium oxide abrasives from the scotch-brite pad between piston cilinder and piston rings 😬
robber576 Won't hurt it. I work on bikes as a side bussiness the oil and fuel mix when combusted in the engine will just blow it all out if the exhaust.
Don't forget to de-rate your torque settings when you lube the threads; stated torque figures are usually for dry threads, unless they specifically say otherwise. I usually de-rate by about 15%. Of course, you can always fall back on the time honored method of tighten until it starts to get easier, then back a quarter turn. Definitely keep using anti sneeze compound though; it's a huge courtesy to the next sucker who has to get in there, and that sucker could be you.
Or just tighten them down and call it good. People get carried away with torque wrenchs. There are very few situations where it is critical. Certainly not lug nuts. It always cracks me up when people use a tq wrench to put on lug nuts. They act like their lawn mower engine is a F1 car or turbofan jet engine.
@@xenonram Applying the correct amount of torque to fasteners isn't bogus, it helps keep the limp wrists and gorillas from losing fasteners or having to repair. Unless you change these fasteners regularly, you won't have a feel for it.

I enjoyed your illustrative and well-edited video of your mechanical experience of attacking your missing coolant problem. I hope the engine responds well to the care.
@@paulsmith9341 It's possible, but the way we used to diagnose a leaky head gasket was to take the rad cap off with the bike running to look for bubbles in the coolant. Typically milky oil in a two stroke is indicative of a bad waterpump seal. It could also be caused from water intrusion from really wet conditions or pressure washing etc...
"2-stroke lawnmowers"? And I thought *I* had too much old equipment in my garage! LOL - thanks for all the laughs (and really educational) content TOT!
When it's a small amount, coming from a point source, you usually get a fan- or wedge-shaped clean area pointing to the source. I found a pinhole through the engine block between the water jacket and the transfer port on an Evinrude 175 HP outboard by this symptom. A nice fan-shaped clean area on the face of the piston in that cylinder (only visible after we had decarboned the motor during one of the MANY teardowns looking for this problem). It pointed right to an invisible leak. We pressurize the water jacket and could see a bead of water form there - it was a drop every few seconds at the pressure we were using, but it was enough to make that cylinder drop out at full power. Ultimately Evinrude replaced the block, but never covered the labor of the many teardowns or removing and reinstalling the block.
No coolant was entering the combustion chamber. The coolant loss was caused by combustion gases leaking into the water jacket, pressurizing the coolant system beyond normal pressures and blowing the coolant out through the cooling system pressure cap.
@@livewire.. thats exactly what i said. no coolant in the cylinder. jesus christ people are thick. I'm fully aware cylinder pressure is greater than cooling system pressure.
One of my lifelong riding buddies was a 3x junior national champ trials bike rider. He and his old man had a sweet track and practice area at their property and the most memorable thing I saw was the Manson family van, and on top of that van was an old 275 gallon water tote. My buddy was riding up the van and on top of that crate at 11 years old. They had dougie lampkin at their property one time. Lot of world class riders at that property over the years, but my friend was, in my opinion, the “craziest.” His dad has a boss boss, and I still see him riding a wheelie on that thing up the road past his house. When I say this kid can ride anything with a motor, I mean it. We had a Kawasaki Mojave that had a GSXR750 motor in it and he would ride wheelies on that quad at 80mph.
Just yesterday i was rewatching some old vids, suffering from lack of ToT content, checking when last ones were made, thinking 'it's about time' and boom, a day later a notification. Needless to say i jumped on it! TBH i'd watch crotcheting, ballet or just paint drying, if it was you who made the vid :D so no worries about different content
*happy noise* :D I'd love more of anything you do Tony, but this kind of stuff reminds me of working on our Sport ATV's with my Dad. Mostly fixing the, 2000 Honda 400, sport type. Awesome video as always.
Your way of jogging back to the stragglers and bringing them back up to the pack without being insulting or boring is appreciated. I kind of know how an engine works but I don't know parts off by heart when I'm looking at a motorbike. Helps me enjoy the video.
That is one of the things I always invest in, CDI/Snap-On torque wrenches. I got used to using them working on multi-million dollar pieces of equipment that goes bang in a mushroom cloud fashion. Some times you only have one chance to do things right before irreversible/expensive things happen. Plus, nice torque wrenches give you that sense of pride that you did things right.
And just where have you been? Do you know what time it is? Your fan base is beside its self, hou march right in there and apologize! Missed you Sir. Glad your here.
Love bikes, TOT, and any type of machine. Its a win win win. I laughed all the way through the video, especially the bit about bending over backwards with a Flashlight bit. Awesome stuff, I'd love to see more bike videos.

Holy shi....stuff! Tony is a trials rider?! That guy is 110% bad a$$!!
My thoughts exactly!!! ;)
He’s a god among men. The only thing better would be if he was a 1000cc class road racer. But trials is impressive in its own right.
Oh how I love those radiator caps! 7 years at a trials bike workshop, and never found any better way of opening them :-)
I'm never here this early, I'm not sure what to do while I wait for everyone else...
Have a beer. Or two. While you're at it, you could help Tony by sweeping the shop, you lazy bastard.
Comment and relish in Tony's soothing voice. Let it lul you to sleep, like a warm blanket.
I'm just used to being "that guy" explaining the grease monkey stuff to the guy with the dumb look on his face after it breaks. Looks like Tony has that under control, this time. I guess I'll just stand here with a dumb look on my face 😆
@@LucIn724 It's OK, we're here. Get watching.
Just wait, and complain.
The torque wrench section has made me realise what AvE has done to my brain.

When you're lacking a torque wrench always use German torque-Gudentight.
I absolutely love this motorhead kind of content. Please keep it coming!
Thanks for the great watch. Been a viewer for several years. It's awesome to hear motor stuff from someone with a great sense of humor on the topic. Seems like most actual motorheads take it too serious sometimes. 10 out of 10. Hope to see some more wrenches poking engines from time to time.
Yes do more videos like this please but also keep the machinist stuff coming.
Well, don't know if anyone else said it but, OF COURSE WE WOULD LIKE MORE CONTENT LIKE THIS!
Thanks ToT :D

Tony, we need you to make a engine from scratch and than build a motorcycle - that would be awesome!!!
Yes please!
Oh, Ya! How about a colab!! Adam can make the crank and Big Clive can make the coil. Fran could probably whip up a spark plug and Mustie1 will say, "Why? I can get engines already made, all day long, for free! And they will RUN!" ;-)

@@jlucasound alex french guy cooking can make the sandwiches :D
I'd love to see him machine one of those small model engines (or even a full size engine). Pretty big project though.
I don’t watch these videos for the machining. I watch them because your comedy is amazing. The machining is just a bonus, and stuff like this is even better.
This guy can talk about painting a house and I'd be down to sit and listen to him talk about how the paint dries, I'm glad I was recommended this.
3:15 FYI, I felt somewhat compelled to subscribe to your channel. But I already had. Weird.

Greecemonkey here!
An easy way to diagnose a head gasket failure is smelling the coolant. If it smells like exhaust, you're in for it.
Always love the videos! Cheers :)
Wait, you're not going to show us the plug after running it for 30 minutes? WTF, Tony?
Ok, here we go... Time to bust a myth. Many people will argue that a high flow water pump is counterproductive to efficient cooling because the coolant spends less time in contact with the hot engine parts and the cool radiator parts, and thereby must be less effective at transferring heat. The opposite is true and here's why: the speed with which heat will transfer from one material to another is directly proportional to the difference in temperature between the two materials. The greater the temperature difference, the faster the heat transfer. Therefore, the more time the coolant spends in any one place, the less efficient the heat transfer becomes. The only exception to this is if the pump is working so hard that cold side hoses collapse or cavitation occurs, both of which limit the coolant's ability to transfer heat. So, generally speaking, more flow and more pressure = better cooling.
Hmmmmm... Cooling system performance, design, analysis (and efficiency) are quite a complex set of related topics… Owing to the nonlinear, multi-variable nature of the physical behaviors involved, these topics defy most simple assumptions as well as simple attempts at optimization. BUT, AS A FIRST ORDER EFFECT, analysis and testing show that for induced-flow-liquid-cooling-systems (i.e. not thermosyphon systems), the benefit in performance (not efficiency) of increasing flow rate is most closely tied to the increase in vaporization temperature of the working fluid (i.e. boiling point) due to increased pressure. Because the heat capacity of vapor is poor, effective cooling with a liquid requires that it stay liquid. Increasing the flow has the potential to increase the fluid pressure at the hottest locations preventing localized vaporization (i.e. cavitation) and thereby might benefit localized cooling where it is most needed (i.e. create better cooling system performance). That said, increasing the local pressure of a working fluid by increasing the flow rate (as opposed to increasing the overall system operating pressure) means doing more work on the working fluid. More work means more heat. More heat means higher working temperatures… It’s a pretty vicious circle where small improvements are hard won.
As for cooling system efficiency; that is a completely different beast. My advice? Stay well clear of using the terms “cooling system” and “efficiency” in the same V-blog comment. Cheers!
I had to read that a few times to grasp that, and it makes sense. The concept of high versus low flow rate is something I've encountered, but never examined... mostly because everything I owned that needed cooling seemed to be working fine without my coming with a headful notions about modifying it.
I was using Boyle’s Law dealing with temperature, pressure, and volume in a closed vessel. But then that was a longtime ago.....
That was a really good video! I specifically appreciated how you make it seem these tasks are within the capability of someone who is not a mechanic. It feels like people have been hugely dissuaded from working on their own motorcars and bikes.
This Old Tony could do videos about doing laundry and i'd watch them
Because you know that somehow a lathe will be involved, and probably an Abom79 cameo. All I know is Stefan will be getting roasted.
"what's happening is a motor is driving a shaft and moving the cylinder and that spins your laundry in the hot water and soap, here let me show you on the lathe." And a joke about using motor oil as laundry soap.
@@Kolajer My dad was a navy machinist at a small base in WW2. They actually did rig a lathe to do laundry.
Not only did you help inspire me when I first started machine, but I have two 1969-1970 Honda Trail 90s I’ve rebuilt and got running (literally second one last night) so this video was spectacular. Anyone who doesn’t like turning wrenches is weird so please make more.
Thanks again for everything Uncle Tony
Your videos are amazing. Still waiting for you to use the mini lathe to improve the mini lathe.
Same!
I'd almost forgotten about the minila the.
Tune in next week for the exciting conclusion of "As the Lathe Turns". Brought to you by "AuntieAbsent Scuba Gear". Only on the ToT Network.
I really enjoyed this, I love your machining stuff but I thoroughly enjoy you explaining other things. You go about things so calmly it's hypnotic and I feel like I learn stuff 😅
"Resist the urge to use any abrasives on this thing" while shoving and washing aluminium oxide abrasives from the scotch-brite pad between piston cilinder and piston rings 😬
robber576 Won't hurt it. I work on bikes as a side bussiness the oil and fuel mix when combusted in the engine will just blow it all out if the exhaust.
Don't forget to de-rate your torque settings when you lube the threads; stated torque figures are usually for dry threads, unless they specifically say otherwise. I usually de-rate by about 15%. Of course, you can always fall back on the time honored method of tighten until it starts to get easier, then back a quarter turn.
Definitely keep using anti sneeze compound though; it's a huge courtesy to the next sucker who has to get in there, and that sucker could be you.
Or just tighten them down and call it good. People get carried away with torque wrenchs. There are very few situations where it is critical. Certainly not lug nuts. It always cracks me up when people use a tq wrench to put on lug nuts. They act like their lawn mower engine is a F1 car or turbofan jet engine.
@@xenonram Applying the correct amount of torque to fasteners isn't bogus, it helps keep the limp wrists and gorillas from losing fasteners or having to repair. Unless you change these fasteners regularly, you won't have a feel for it.
Extra points for the sneaky Subscribe edit. Although it may have been so sneaky that most people missed it.
I just love your videos ToT. Now that I know you’re not just a machinist I have an even higher level of respect for you as well. Looking forward to future videos.
Tony, you always have and always will be an inspiration. Great to see your son included in the videos, later in life he will realise (if he hasn't already) his dad is a genius and an awesome youtuber. Kindest regards from Bonnie Scotland. Joe.

I seriously thought the title said “The Mystery of the Missing Content.” Made me think, ‘yeah, where has TOT been?’
Oh man, I so luuuuurve your videos, your subtle but awesome sense of humour cracks me up!
Nice work Tony. 👍
I enjoyed watching your videos before, but now as a mechanic and Sherco Enduro bike owner, TOT is even more awesome.
Cheers mate, from Australia 🇦🇺
I enjoyed your illustrative and well-edited video of your mechanical experience of attacking your missing coolant problem. I hope the engine responds well to the care.
The 'Subscribe' was so well done it was almost too subtle. Another great vid :)
*Jamie Rogers* It snuck past me! I was busy thinking about my own bike that overheats and that I really should stop doing nothing about it.
This was actually incredibly informative and I appreciated this video. Thanks again, Tony!
Love it. I`m learning. Whatever you do you are always entertaining and insightful. Thank you brother. Much appreceiated.
That was great! Keep 'em coming! I don't have a bike (or a place to work with them) myself anymore, so it's great fun to hear someone else doing it!
No matter what you make a video about, i learn something. Keep it up!
It's a two stroke. Thats not engine oil, it's clutch and transmission oil! I know I'm nit picking, but it does bug me.
I've seen many 4 stroke mechanics make this mistake... A blown head gasket on a 2 stroke doesn't cause milky gear oil (the cases are sealed).
@@shredenberms9603 would it cause oil /fuel in the coolant?
@Lassi Kinnunen into the coolant passages? It shouldn't.
Actually I was wondering, why the combustion chamber isn't cleaner, like when water/coolant enters into it...
@@paulsmith9341 It's possible, but the way we used to diagnose a leaky head gasket was to take the rad cap off with the bike running to look for bubbles in the coolant. Typically milky oil in a two stroke is indicative of a bad waterpump seal. It could also be caused from water intrusion from really wet conditions or pressure washing etc...
You know its a good day when you watch a new This Old Tony video! Keep up the amazing work! Peace.
"2-stroke lawnmowers"? And I thought *I* had too much old equipment in my garage! LOL - thanks for all the laughs (and really educational) content TOT!
if coolant was getting in the combustion chamber your piston dome would have been clean.
When it's a small amount, coming from a point source, you usually get a fan- or wedge-shaped clean area pointing to the source. I found a pinhole through the engine block between the water jacket and the transfer port on an Evinrude 175 HP outboard by this symptom. A nice fan-shaped clean area on the face of the piston in that cylinder (only visible after we had decarboned the motor during one of the MANY teardowns looking for this problem). It pointed right to an invisible leak. We pressurize the water jacket and could see a bead of water form there - it was a drop every few seconds at the pressure we were using, but it was enough to make that cylinder drop out at full power. Ultimately Evinrude replaced the block, but never covered the labor of the many teardowns or removing and reinstalling the block.
No coolant was entering the combustion chamber. The coolant loss was caused by combustion gases leaking into the water jacket, pressurizing the coolant system beyond normal pressures and blowing the coolant out through the cooling system pressure cap.
@@livewire.. thats exactly what i said. no coolant in the cylinder. jesus christ people are thick. I'm fully aware cylinder pressure is greater than cooling system pressure.
@@PeterWMeek the piston was evenly coated in carbon. no water in the combustion chamber. this is not debatable.
All that carbon build up on the piston just gives you more compression.
*Salty Steel* ...and messes up gas flow and may cause pre-ignition.
Douglas
That never happens to me.
@@BigHeretic It's not some high compression/high power engine. On this engine, the gas will never know there is carbon build up there.
One of my lifelong riding buddies was a 3x junior national champ trials bike rider. He and his old man had a sweet track and practice area at their property and the most memorable thing I saw was the Manson family van, and on top of that van was an old 275 gallon water tote. My buddy was riding up the van and on top of that crate at 11 years old. They had dougie lampkin at their property one time. Lot of world class riders at that property over the years, but my friend was, in my opinion, the “craziest.” His dad has a boss boss, and I still see him riding a wheelie on that thing up the road past his house. When I say this kid can ride anything with a motor, I mean it. We had a Kawasaki Mojave that had a GSXR750 motor in it and he would ride wheelies on that quad at 80mph.
Geared up for these Gear-head vids. Thanks a lot Tony the Tiger.
I'm all for adding some trials bike content, both wrenching and riding :)
Just yesterday i was rewatching some old vids, suffering from lack of ToT content, checking when last ones were made, thinking 'it's about time' and boom, a day later a notification. Needless to say i jumped on it!
TBH i'd watch crotcheting, ballet or just paint drying, if it was you who made the vid :D so no worries about different content
Just realized that This Old Tony is actually Toni Bou. Mindblowing
I must admit, your videos are always a blast

That is one of the things I always invest in, CDI/Snap-On torque wrenches. I got used to using them working on multi-million dollar pieces of equipment that goes bang in a mushroom cloud fashion. Some times you only have one chance to do things right before irreversible/expensive things happen. Plus, nice torque wrenches give you that sense of pride that you did things right.

Hey viewer, be sure to use the wet torque rating if you're going to never-seize the bolts, lube lets you overtorque
Love bikes, TOT, and any type of machine. Its a win win win. I laughed all the way through the video, especially the bit about bending over backwards with a Flashlight bit. Awesome stuff, I'd love to see more bike videos.
Tony , I sit & nearly wet myself laughing at the subtle jokes you insert . Spent 40+ years working in the car / truck / tractor / motorcycle / boat & black hole maintenance trade . Wonderful work presented in a wonderful & humorous way and I appreciate you showing when things do not go perfectly for you . Keep up the good work
