You are completely correct about the lighter pistons, the reduction in mass doesn't give any more power by itself. Lighter pistons reduce peak forces on the conrod and crank, so could enable the engine to run safely at a higher RPM (valvetrain depending) which may enable more power to be extracted with other modifications. Lighter pistons tend to be modern short skirt low friction designs, so may give a little more power from reducing frictional losses.
There are a couple good videos (probably many more I haven’t seen) from Engine Masters and Salter Racing Engines. A lighter piston by itself will indeed decrease forces on the Rods and Crank, but as you mentioned the piston shape changes, which in turn makes the rods longer and the skirts shorter, which has other effects, such as timing & particularly ring seal. I think Wes has it nailed, it will have a similar effect on responsiveness to a lightweight flywheel but ultimately engine power won’t change considerably and similarly to exhaust you trade low end torque for high rpm hp. Ultimately the best design is going to be dictated by the type of use the engine will see.
that car in that condition is a guaranteed boy magnet. she will have no shortage of guys trying to impress her by fixing her ride. Dad ain't stupid, free repairs.
I remember The Car Wizard talking about how people delude themselves when they decide to get an old car running. They have a budget to get the engine started and the wheels turning. That's as far as they think it out. They're not expecting to get hit with the cost of bearings, brakes, lines, tires, etc. Before they can use the car in any meaningful way.
I think you're spot on Wes. When I installed a light weight flywheel on my turbo volvo some of my friends said I was gonna lose so much torque by replacing the old 12-13Kg stock flywheel. I replied that that is plain wrong, as the flywheel does not produce torque, it just stores rotational energy inbetween pulses. Hence making the car harder to drive/easier to stall out during launch, but way quicker to accelerate. Other lightweight engine internals would only add to that effect in my opinion.
Had a compact car with a 2.0 four-banger, but the same engine was also used in a much larger model. I once needed a new engine and the junkyard had one out of that large model. Guess what - its flywheel was about two times the weight! Had my old one, so no poblem.
You're not wrong about the flywheel, but when it comes to the pistons, I disagree. There is an awful lot of energy expended by accelerating and decelerating a piston repeatedly. It is not recovered, it is wasted, because a piston is not rotating. Less piston mass = less waste. A flywheel does not CHANGE velocity at a constant RPM. A piston CHANGES velocity constantly, even at constant engine RPM. This is wasted energy.
Love all your videos that involve solving problems (versus other channels where too much content is making shop tools and stuff). I have a weird soft spot for reviving (or attempting to repair) stock vehicles that otherwise would head to the scrap pile
Congrats on 300K subscribers Wes, now on to a Million! With a car of that "caliber" that someone wants fixed, it's for multiple reasons: 1. They enjoy pain and suffering, their own or others. 2. Some people are consistent at making terrible choices. 3. 25 yrs ago someone got lucky 'once' in that car, they're still holding on to that. 4. The kid is spoiled and this is a life lesson 5. Used car prices are still out of control Congrats, you read into a comment section about a Chrysler Sebring, now go off and do something amazing!
My wife had a car just like this back in 2004. Our oldest son was 16 at the time, and was learning to drive. Flipped it 4 times end over end. No injuries but that was the best thing that ever happened to that car.
The last time someone told me my car had a bad crank position sensor was the death of that car. I am still pissed about it to this day. I took a 1991 Oldsmobile Cutlass Supreme from barely running and pissing coolant out of every gasket (typical 60 degree V6 of that era) to completely sealed and running perfectly at 16 years old. It took me months and I had no idea what I was doing, but managed to get through it. I was so proud of myself. The first day I had that car on the road I drove it EVERYWHERE. On my last trip away from home it died completely and I got stranded in town. Would crank and crank and crank but not even cough. A random guy came up to me, looked around and told me the same thing. I had a little hope so I took it home and spent every single day after school bent over inside of the engine bay trying to get that sensor out. For months I did this in the dead of winter in Indiana. No matter what I could not get it out. I even tried removing the oil pain to push it out from the bottom but it was impossible. I ended up being forced to sell that car and within a month ended up with another 3.1 car (Grand Prix) which I drove for the rest of high school, but the amount of devastation I felt after that day was absolutely unreal. Came from an extremely poor family and I had to go back to taking the bus to school. I will never know what was truly wrong with that car and I don't have the closure I deserve lmao. Sorry for the story, but man that shit still gets me to this day, 16 years later.
I have a similar story but nowhere near yours. Back in 2015 my dad was going to either sell his 90s something F150 or hand it down to me, he ended up selling it to a neighbors kid for $3000 and now its just rotting away in their backyard it was nice but im sure its junk now.
Wes, when I raced go karts back in the early 60s a light flywheel made a huge difference in quick acceleration and allowed a fast spin up to high RPM. We even removed the magnets and ran them on constant loss batteries. Also taking 5 lbs off a VW 17.5 lb flywheel gave a similar result. In both cases engine modification enhanced the effect. Glad you were able to fire up the Chrysler!
Yep, replacing a cast iron 5HP flywheel with a 3HP aluminum or cast iron flywheel makes a HUGE difference, AND it is incredibly dangerous, which is why it was specifically outlawed by the legitimate sanctioning bodies
Pretty sure you're right on your assessment at the end. Changing the mass alone won't increase power, but it allows you to do other things that will and increase responsiveness. Makes sense to me. Disclaimer: My degree is in software engineering, not mechanical.
my Pops tore apart a huskqvarna riding mower with a kohler engine. it sat for 2 years. I had a literal bucket of bolts to piece it back together. this vid brings back those good memories
I thought driving a clapped-out death trap to college was a given...

Mad respect to you Sir, on so many levels. I wouldn't change a single thing about, how you put together your videos and the structured content.Your videos captivate me, where I always have to watch them all the way through to the end, every time.
I think you're spot on with that piston theory. It's kinda like how people think high octane fuel works; it doesn't simply make more power, but rather allows for more power to be made with other appropriate changes. More octane allows more timing, lighter rotating mass allows higher RPM.
Higher octane means higher compression ratio, higher compression ratio - more power. If you put low octane fuel in engine with higher compression engine it will self combusting, like a diesel - knocking, in case of gas engine
@@oleksandrkomisarenko8118 _"Higher octane means higher compression ratio"_ It means you can _use_ a higher compression ratio before detonation becomes a problem. It doesn't magically give a higher CR.
That's why F1 engines had up to 12 cylinders with only 3.5ltr displacement. Lower oscillating mass allow for higher redlines, resulting in more power... At least that's my theory... 😊😇🥸
@@horstszibulski19 redline depends on a lot of factor, like: camshaft profile, valve inertia, piston weight, piston ring thickness etc. Dividing engine on more cylinders is a, kind of, one of the possible way to increase redline by decreasing the piston weights
The lighter mass of the system changes the entropy of the system. However power is made from an explosion and if the parameters for that are unchaged, then the power output cannot be different. You are a master baiter for driving engagement in your comments. Well done Wes.
It would be a great ”interview series” on your channel. You hunt down the engineer responsible for the most stupid car-designs evere made, and ask them what thet were thinking 😂
@@MrShobar two things can be true at once: 1. it does because he actually went to school for something meaningful. Edit: the vast majority of people don’t. 2. He could have taken that 150ishk and invested it and had millions more dollars. He works with his hands, you can only do that full time for so long in many cases. I don’t think a degree you don’t mostly take advantage of that makes you millions of dollars more poor in your life is worth it.
I work with engineers every day. There's a lot of things many of them can do, however systematically troubleshooting problems is NOT one of those things. VERY few of them possess this ability, which I believe is at least partly genetic, and VERY hard to teach into an automatic skill.
My first car cost me $200.00 and I paid for it, not my Dad. I traded it in soon enough, but It worked long enough to get me back and forth to High School for 2 years. No one, including you, knows how well this man's daughter drives. That makes this the perfect car for her to start on. The riddance of the smell will help her build character and then decide whether she wants to walk, take a bus, or drive to class.
It’s always a pleasure to watch you work Wes! You’re pretty much unflappable in all situations, and your engineering education and experience get you through even the toughest problems.
You gotta imagine someone read the code, told him it was the cam sensor, and then he couldn't find that part listed bc it's part of the dizzy, and ended up convincing himself they must've meant/said crank sensor
That's definitely one of those vehicles where you do the world a favor and park it in the trees and slowly back away from it. You were definitely reading my mind Wes, WHY would anyone want to save one of those...
There's no primary cost to the car, if it runs and does not cost too much to get roadworthy, it's a spare car which when your own breaks down, which it will, allows you to go and get parts to fix it,or to drive until your mechanic can fix the primary one. Should you have ever tried to borrow your dearly beloveds car to do these things, you know you need a spare. ! Should you already have a spare, your wifes car will break down and she will demand yours, you'll be driving the spare and it will fail to start one morning when you have to get somewhere. one or more spare motors is good...
There are far better choices for first cars or spare cars. Even if this thing was free, it would be far more useful if it was recycled into something else.
Hey Wes I know the perfectly good explanation, it's called it costs 60 grand for a new one plus 10 percent interest. You wouldn't believe the older cars ive seen on the road in the last couple years
Yikes...30 yo Chrysler...sitting for 9 years...partially taken apart and DIYed? Needs to be just left in a field, not good enough to even go to a scrap yard! 😁 Thanks for the videos! 👍👍
We cross shopped every convertible of this era. Volvo, Mercedes, Saab, Mitsubishi and others including the Sebring. Ended up with a three year old 2000 Toyota Solara that has been dead nuts reliable for 21 years. My wife finds it a little boring but a Toyota will bore you for 300,000 miles. We aren't even half way there yet.
I guess I forgot how much I liked hearing the commentary as Wes worked on one of these beasts. Did you notice the military mission planning demeanor once he had that car on the lift? On a more serious note… I have a 2007 6.6 Duramax with a FASS fuel filter lift pump assembly. As per the directions from FASS the pump is on when the key is turned to ON. The ONLY way to turn the pump off is by turning the key to OFF. After hearing Wes describe the danger of a fuel pump wired this way I need to make a change… but what could that be?
External battery hookup running 2 electric fuel pumps under the hood just to see if it would run? That's the bank robbery scene from Dirty Harry: "...I gots to know!"
1st) This exact car (color), condition... was my first car. I have it to this day. Paint looks exactlyt he same. Ive already addressed all the problems you documented - brake lines, fuel line, fuel tank straps, fuel pump (wise you didnt take the job), among other major things like timing job and a cobbled exhaust (the resonator turns into composted metal by now). I learned most everything I know because of this car...on hard mode...because of the way that it is. 2) the rotating mass problem when looking at it from a power point of view isn't sufficient, because you have to approach it from a rotational inertia and ENERGY point of view. AKA delta RPM/time with "the same" power (no other variables changed like displacement, compression, flow, etc). The layman's intuition feels this as throttle response, even though you can make the same power anywhere in the RPM curve,- your ability to change engine speed in less time (less rotating mass), means less ENERGY is used over the rev range. Mathematically you get ENERGY = POWERxTIME, if accelerating the engine takes LESS TIME, it "uses LESS ENERGY", even with the "SAME POWER". This energy is all in the reference frame of the engine itself. So when you apply total energy, such as losses in the drivetrain, and when compared to the total mass of the vehicle - its pretty much negligible unless you're really justifying every last ounce of energy.
I Helped diagnose/work on similar non/convertible Seebring....once. the challenge was that there were multiple places the engine had sensors for safety. One sensor not getting the signal, no run. Period. Would not allow the fuel pump to be turned on. We had spark,cwe had distributor movement, but the car refused to turn on fuel. Once we figured out the issue several hours into this adventure, it was a tiny sensor. It had gotten broken as I recall. Once the sensor had been replaced, distributor or cap reassembled, it too moments and the pastor's car was running once again. We began fairly early morning by memory and we left after dark roughly this time of year. I am happy you got it running, Wes! I figured you were correct or some other sensor was keeping the fuel pump off. Well done! Thank you for sharing. And if structurally stable, with Much cleanup, why nor run it? It is a running paid for car. Much beats a loan and payments.
My thoughts on the lighter piston and rods is just what you said. It's not a direct gain in HP or torque but it will rev faster which allows for quicker times to higher HP limits. Max RPM may not change without differant valve springs etc as needed.
Also agreed! Lower mass means it will rev quicker, but power is the same. Perhaps another way of looking at it - just lowering rotating mass does not increase the amount of air/fuel that can go through the engine. That's what makes power.
I bought one of those brand new in 1996, It was a fun summer car, and ours never saw salt in its lifetime. ... That engine produced adequate power, and was relatively economical. All good.....if you like a cheap vehicle stamped out of a piece of sheet metal. Ours eventually needed a instrument cluster, so I found a used one in NJ for a good price.....as Chrysler quit parts support in the early 2000's. We sold it shortly thereafter, as any impending repair would probably exceed the value of the vehicle. Great video, thanks !
fantastic video i have been presented with years sitting cars and told if you can get it running you can have it. Idrove a brush painted 69 vw all thru college and fixed what broke as needed you could have stopped at the metal intake manifold and i would have been impressed. the return on investment alone on that 3/4 tank of 9 year old fuel should pay for a fuel pump! well done and have a superb week
this car was way ahead of its time, now ALL the cars are junk like this, not serviceable, crappy components, undesired, etc. PS: you're wife is the best, no lady should be allowed to be closer than 30ft to this mice fest.
Assuming the drawing on the blackboard was your friend’s intended change you will increase the rod length which will result in more constant volume combustion. This will increase cylinder pressures through a great er amount of crankshaft rotation resulting in more torque through greater amount of crank rotation which will result in more power. The reduction in rotating mass will only effect throttle response, it would achieve the same result by throwing a light weight flywheel on it and he would not have to disassemble the engine replace a bunch of parts have the rotating assembly rebalanced, etc….
You love to do what most can't and it sets you apart from everyone else. Being Mr. individual makes you so happy your'e willing to take on the near imposable. Don't change for anyone I love your videos. Keep them coming!
I have a neighbor who has one of these but a little older year. He drags it to the mechanic once every could years then drags it back and covers it up. In five years I’ve yet to see it run.
Those Mitsubishi 6G series engines were great, simple and reliable workhorses. Just needed a timing kit ever 100k and valve cover and cam thrust plate and distributor o-rings changed to keep it leak free
Growing up in the salt belt of NY I think thats the 1st time ive even seen a "nice" one that wasnt rusted out. These cars always seem to be held together with spray foam, bondo and hope and dreams.
The math; A new car that costs $50,000 will depreciate 10-15" a year. So $5,000 loss in value based on age alone. Plus you had a down payment and monthly charges and a higher insurance. Now, youi have a car that does not run but is paid for. You need a car. If it costs $5k to fix the car then you will have transportation which quite likely will last a minimum of 1 year. Probably more. You are way ahead fixing the car. Click and Clack.
Wes, i commend you for even attempting to repair, or make it run. What is the matter with people, they do the minimum maintenance and expect you to be a miracle man!!
You literally just gave me *PTSD* from the thumbnail!! 😵 My sister had the exact car. It was a NIGHTMARE to work on. Man oh man. I don't even drink Wes, but I gotta get some whisky after this video ☠️ lol
Had a similar save for the kids with a friends convertible Sebring. Found oil streaming out of the head gasket behind the rear cylinder head. It was bad, the hotter the engine the more oil oozed out. Told him I wanted to try something. Pulled the manifold, removed the rear valve cover, found 4 less than tight head bolts. Re-torqued all of them and it stopped leaking. Last I talked to him was a year later and the kids were still driving it.
Hi Wes, I disagree with your con-rod theory. Simply because you failed to take into account the added "work" provided by combustion. This adds an immeasurable amount of force on the downwards stroke. Dude, I LOVE your videos.
UK main dealer master-tech here, - where's your sense of adventure, back seat out, angle-grind a square out just smaller than a stick-on sound deadening pad, pump out, pump in, bray it down, stick pad on, seat back in, job done... [any leaking pipes are for another episode] [of course i would never do that at work...]
These gems were hitting 5-6 years old when I started wrenching professionally. SO. MANY. NEONS. and Sebrings. And Concordes. And Intrepids. Oh god. I have a visceral reaction to seeing these on the road - at least they’re few and far between nowadays.
Yeah I remember those 4 bangers blowing head gaskets all the time. The heads were always warped. You'd fix them and they'd last about 50,000 miles and blow again.
My wife saw this video come up on our feed and said, "He should change his channel name to 'Why Wes, Why'," without missing a beat.

Thinking about "float" lighter may allow quicker response.
They allow faster rpm increase,decrease less strain on rods and cranks.
Having overall less weight generally would also give you better economy/more power -weight ratio

No one, including you, knows how well this man's daughter drives. That makes this the perfect car for her to start on. The riddance of the smell will help her build character and then decide whether she wants to walk, take a bus, or drive to class.
It’s always a pleasure to watch you work Wes! You’re pretty much unflappable in all situations, and your engineering education and experience get you through even the toughest problems.
You gotta imagine someone read the code, told him it was the cam sensor, and then he couldn't find that part listed bc it's part of the dizzy, and ended up convincing himself they must've meant/said crank sensor
That's definitely one of those vehicles where you do the world a favor and park it in the trees and slowly back away from it. You were definitely reading my mind Wes, WHY would anyone want to save one of those...
There's no primary cost to the car, if it runs and does not cost too much to get roadworthy, it's a spare car which when your own breaks down, which it will, allows you to go and get parts to fix it,or to drive until your mechanic can fix the primary one. Should you have ever tried to borrow your dearly beloveds car to do these things, you know you need a spare. ! Should you already have a spare, your wifes car will break down and she will demand yours, you'll be driving the spare and it will fail to start one morning when you have to get somewhere. one or more spare motors is good...
If it runs and drives that’s all that matters.
Might be for a kid’s first car. Would make sense for that
There are far better choices for first cars or spare cars. Even if this thing was free, it would be far more useful if it was recycled into something else.
Hey Wes I know the perfectly good explanation, it's called it costs 60 grand for a new one plus 10 percent interest. You wouldn't believe the older cars ive seen on the road in the last couple years
True. Very true.
The only reason I can think of is to teach an entitled kid a lesson.
When you want to drive a car with a sketchy fuel system You always want your wife to drive it first. Good job Wes.
You are such a genious. But the minute you got it running, I loved your evil scientist laugh. That was brilliant.
Thank you for your continued glimpses into your life. I love these videos!
Yikes...30 yo Chrysler...sitting for 9 years...partially taken apart and DIYed? Needs to be just left in a field, not good enough to even go to a scrap yard! 😁 Thanks for the videos! 👍👍
Oh ,I don’t know, up here in upstate NY in running condition that car would be listed for $9000. A marketplace special.
With regards to your piston thing…I think you are spot on. Lighter is probably more snappy but not necessarily more power.
It would be interesting to see some Richard Holdener style dyno testing on this subject though
Good job getting her running.
We cross shopped every convertible of this era. Volvo, Mercedes, Saab, Mitsubishi and others including the Sebring. Ended up with a three year old 2000 Toyota Solara that has been dead nuts reliable for 21 years. My wife finds it a little boring but a Toyota will bore you for 300,000 miles. We aren't even half way there yet.
I love you're mechanic videos....I'm always learning something new from a pro.😮❤
I guess I forgot how much I liked hearing the commentary as Wes worked on one of these beasts.
Did you notice the military mission planning demeanor once he had that car on the lift?
On a more serious note… I have a 2007 6.6 Duramax with a FASS fuel filter lift pump assembly.
As per the directions from FASS the pump is on when the key is turned to ON. The ONLY way to turn the pump off is by turning the key to OFF.
After hearing Wes describe the danger of a fuel pump wired this way I need to make a change… but what could that be?
I think the diesel would be a lot safer than gasoline in any case, so it's probably not something to lose too much sleep about.
Go find an inertia switch out of a Ford.
@tomkrause62 Cleet proabably has a pile of them he's stripped out of his fleet of Crown Vics...
Agree... snappy rotation...same power... good content and thanks...🔧🔧👍
Wes you owe your wife a nice dinner for getting in that car.
Gosh, if it weren't a ragtop you could just mount a replacement gastank on the roof. Nice work.
External battery hookup running 2 electric fuel pumps under the hood just to see if it would run? That's the bank robbery scene from Dirty Harry: "...I gots to know!"
Thanks for persevering with the investigation!

Owner breaks bolt trying to fix CPS. Parks car for NINE years.
Nine stinky years 😅
Priorities
Hey, Wes! You can read people's minds too?! That was EXACTLY what I was thinking... "Why?!"
Chewed in twoed. Brilliant.
Fixed the fuel system, hillbilly style,with the click clacker 500 fuel pump. Good job!😂
David Freiberger would be proud with your use of a zip tie~
Cool red panda costume.
Though the panda seems a little vicious.
1st) This exact car (color), condition... was my first car. I have it to this day. Paint looks exactlyt he same. Ive already addressed all the problems you documented - brake lines, fuel line, fuel tank straps, fuel pump (wise you didnt take the job), among other major things like timing job and a cobbled exhaust (the resonator turns into composted metal by now). I learned most everything I know because of this car...on hard mode...because of the way that it is.
2) the rotating mass problem when looking at it from a power point of view isn't sufficient, because you have to approach it from a rotational inertia and ENERGY point of view. AKA delta RPM/time with "the same" power (no other variables changed like displacement, compression, flow, etc). The layman's intuition feels this as throttle response, even though you can make the same power anywhere in the RPM curve,-
your ability to change engine speed in less time (less rotating mass), means less ENERGY is used over the rev range. Mathematically you get ENERGY = POWERxTIME, if accelerating the engine takes LESS TIME, it "uses LESS ENERGY", even with the "SAME POWER". This energy is all in the reference frame of the engine itself. So when you apply total energy, such as losses in the drivetrain, and when compared to the total mass of the vehicle - its pretty much negligible unless you're really justifying every last ounce of energy.
FYI, the sound and picture quality are awesome. Interesting and informative as usual. Thanks.
@14:49 the forth wood screw for your PCM is there on the cowl.
I Helped diagnose/work on similar non/convertible Seebring....once. the challenge was that there were multiple places the engine had sensors for safety. One sensor not getting the signal, no run. Period. Would not allow the fuel pump to be turned on. We had spark,cwe had distributor movement, but the car refused to turn on fuel. Once we figured out the issue several hours into this adventure, it was a tiny sensor. It had gotten broken as I recall. Once the sensor had been replaced, distributor or cap reassembled, it too moments and the pastor's car was running once again. We began fairly early morning by memory and we left after dark roughly this time of year. I am happy you got it running, Wes! I figured you were correct or some other sensor was keeping the fuel pump off. Well done! Thank you for sharing. And if structurally stable, with Much cleanup, why nor run it? It is a running paid for car. Much beats a loan and payments.
The end section talking about the question of the lightweight pistion was some of the most enjoyable content you've made, fan of 5 years!
My thoughts on the lighter piston and rods is just what you said. It's not a direct gain in HP or torque but it will rev faster which allows for quicker times to higher HP limits. Max RPM may not change without differant valve springs etc as needed.
Agreed.
Also agreed! Lower mass means it will rev quicker, but power is the same. Perhaps another way of looking at it - just lowering rotating mass does not increase the amount of air/fuel that can go through the engine. That's what makes power.
@@kd5byb good point.
Drag Racing engine Builders do it all the time.....more Rpm, more Hp....
Agreed. Honda has tested many motorcycle racing engines that make higher hp at higher rpm’s.
Thanks, Wes, your objectivity is priceless !!!
I bought one of those brand new in 1996, It was a fun summer car, and ours never saw salt in its lifetime. ... That engine produced adequate power, and was relatively economical. All good.....if you like a cheap vehicle stamped out of a piece of sheet metal. Ours eventually needed a instrument cluster, so I found a used one in NJ for a good price.....as Chrysler quit parts support in the early 2000's. We sold it shortly thereafter, as any impending repair would probably exceed the value of the vehicle. Great video, thanks !
Look at Wes flexing that Calculus II muscle memory with the integrals reference. Great videos, by the way!
“My father wouldn’t do that “
A happy Wes is a rare sight
24:05 Let's cross our fingers and hope nothing catches on 🔥🚒 bcs I won't be putting it out ☠️🤣🤣🤣🤣
I love this guy 🔧🔧 WWW👏👌💪
I still have PTSD from a crank sensor that broke off in an 8.1L in a 2500 avalanche.
The spiritual successor to the Le Baron. Very nice.
You are multi-talented. You sew, too!!! ❤❤❤
fantastic video
i have been presented with years sitting cars and told if you can get it running you can have it. Idrove a brush painted 69 vw all thru college and fixed what broke as needed
you could have stopped at the metal intake manifold and i would have been impressed.
the return on investment alone on that 3/4 tank of 9 year old fuel should pay for a fuel pump! well done and have a superb week
it has gained value in those years
this car was way ahead of its time, now ALL the cars are junk like this, not serviceable, crappy components, undesired, etc. PS: you're wife is the best, no lady should be allowed to be closer than 30ft to this mice fest.
I just now caught this recent video I just want to say I love your videos they're great👍😃
I love how happy you get when something works!
Assuming the drawing on the blackboard was your friend’s intended change you will increase the rod length which will result in more constant volume combustion. This will increase cylinder pressures through a great er amount of crankshaft rotation resulting in more torque through greater amount of crank rotation which will result in more power. The reduction in rotating mass will only effect throttle response, it would achieve the same result by throwing a light weight flywheel on it and he would not have to disassemble the engine replace a bunch of parts have the rotating assembly rebalanced, etc….
Some days, you measure your success literally, other days, figuratively.
The long way around the barn.
😊
You love to do what most can't and it sets you apart from everyone else. Being Mr. individual makes you so happy your'e willing to take on the near imposable. Don't change for anyone I love your videos. Keep them coming!
I absolutely loved this video. You almost always fix a problem. Always enjoy your videos. Thank you for sharing 👌 😊
Hahaha for a kid in school, that's not a mode of transportation, it's a hard hard hard life lesson!
I have a neighbor who has one of these but a little older year. He drags it to the mechanic once every could years then drags it back and covers it up. In five years I’ve yet to see it run.
That opener was hilarious. Thanks for the video Wes🐾🍺
Those Mitsubishi 6G series engines were great, simple and reliable workhorses. Just needed a timing kit ever 100k and valve cover and cam thrust plate and distributor o-rings changed to keep it leak free
Thanks for the video Wes and Family!
Growing up in the salt belt of NY I think thats the 1st time ive even seen a "nice" one that wasnt rusted out. These cars always seem to be held together with spray foam, bondo and hope and dreams.
Oh I have nightmares about one these cars. It kept coming back and had way too many miles on it. Good luck wes
Ha ha ha! CNC to DNR... I love this channel. We had one of those at school 3 years back. Flashbacks galore Good times. Good times.
The math; A new car that costs $50,000 will depreciate 10-15" a year. So $5,000 loss in value based on age alone. Plus you had a down payment and monthly charges and a higher insurance. Now, youi have a car that does not run but is paid for. You need a car. If it costs $5k to fix the car then you will have transportation which quite likely will last a minimum of 1 year. Probably more. You are way ahead fixing the car. Click and Clack.
Wes, i commend you for even attempting to repair, or make it run. What is the matter with people, they do the minimum maintenance and expect you to be a miracle man!!
You literally just gave me *PTSD* from the thumbnail!! 😵 My sister had the exact car. It was a NIGHTMARE to work on. Man oh man. I don't even drink Wes, but I gotta get some whisky after this video ☠️ lol
Had a similar save for the kids with a friends convertible Sebring. Found oil streaming out of the head gasket behind the rear cylinder head. It was bad, the hotter the engine the more oil oozed out.
Told him I wanted to try something. Pulled the manifold, removed the rear valve cover, found 4 less than tight head bolts. Re-torqued all of them and it stopped leaking.
Last I talked to him was a year later and the kids were still driving it.
Hi Wes, I disagree with your con-rod theory. Simply because you failed to take into account the added "work" provided by combustion. This adds an immeasurable amount of force on the downwards stroke. Dude, I LOVE your videos.
That's for both pistons the same
Right.
Added work? It’s the same amount of work as a stock piston. Not like he’s increasing the compression ratio, just decreasing the mass of the piston.
UK main dealer master-tech here, - where's your sense of adventure, back seat out, angle-grind a square out just smaller than a stick-on sound deadening pad, pump out, pump in, bray it down, stick pad on, seat back in, job done...
[any leaking pipes are for another episode] [of course i would never do that at work...]
These gems were hitting 5-6 years old when I started wrenching professionally. SO. MANY. NEONS. and Sebrings. And Concordes. And Intrepids. Oh god. I have a visceral reaction to seeing these on the road - at least they’re few and far between nowadays.
Yeah I remember those 4 bangers blowing head gaskets all the time. The heads were always warped. You'd fix them and they'd last about 50,000 miles and blow again.
The grin and joyous laugh after the motor ran proves Wes has gone ‘round the bend.😅
Congrats on 300K!! 🎉😊
You're 100% correct on both not removing the gas tank and light verses heavy you should be starting snow plow repair season soon 😊
We may hate working on them sometimes, but in the end, seeing a bag of shit like this start and idle is a great feeling that never gets old.
