What is valve float?
Expensive, once the piston whacks it..
Yep
Truee❗️🚫🧢
Happened to me in an E250 diesel...worst day/week ever
Knock knock knocking on cylinder four or whatever guns and roses said
Makes perfect sense to me the OEM manufacturer knows what they're doing it takes years of research and development for them to design a bike to run the way it runs. What I do know is if I ever do by a 4 stroke I will be sure to keep this in mind if the bike ever needs valves I will be sure to replace them with what originally was meant to be in the bike. Your wooden valve actually works really well for explanation purposes. That helps me understand it perfectly. Thanks buddy I appreciate these videos
Original all the way
Finally explained in a way I can understand. Thanx dude.
Awesome
Coolest diagram ive seen lol good work at explaining it to👌🏻
Awesome man
Thank you for helping me to understand this. The reason I was researching this topic is because after recently having my oil changed and a new oil filter put on, the next day a “service engine” light came on so I took it to have the error code read. It said PO304 “cylinder 4 misfire.” I just assumed it was time for a tuneup, so scheduled it with my mechanic. Anyhow, trying to put this in a nutshell. The engine made a terrible noise, then stopped. My mechanic found the number 4 spark plug smashed closed, so he believes that when they changed the oil filter something was dropped into the air induction hose. The other 3 cylinders, plugs were fine, good compression, cam timing was good, leak down test failed..etc. When I presented this information to the oil change place, their reply was that most likely a “floating valve caused the engine to fail. It’s a 2001 Ford Escort, 148,000 miles, but well maintained. I’m not sure what to do now. Thanks for your video.
Hard to imagine you revved up the engine that high to float a valve... But it's possible
I know this is an old video, and as others say, it's a very helpful video, using wood is probably even more helpful than using the actual engine to describe the condition! Thanks
Happy you liked it
Love Romanian peoples intelligence. Thank-you mate
Valve float can appears when the spring is tired and need replacement with an original one. If floating already there since awhile then better replace the springs and the valves
True
excellent explanation, thank you!
Thanks for watching
That was an AMAZING explination! The model really helped understanding the whole process. Thank you very much :)
Thanks for watching man.. And commenting
I LIKE your "tech" style video's like this sir the way you do these video's are great.
Thanksnman
no problem sir.
To answer your question, you are right bro
first video to explain the valve float, excellent, Bravo brother !!!!!!!!!!!!!!!!!
Awesome to have you here...
Yamaha s ran titanium valve s on the WRS and the pecker heads were Slack cleaning air filter s and dust and crud damaged the valve s fairly quickly 😢
Sorry, I didn’t realize this is a motorcycle channel. Still a nice simply explained video. Thank you
Glad to have you here
Amazing explanation!
Thanks for the explanation...👍
Glad you liked it
My boi has titanium springs and his bike revs like 3,000 rmp higher
Yep titanium it's fun man
2 strokes dont need valaves hahah
CherokeeXJ technically reeds are valves.
Great video and perfect explanation for my noob mind
Glad you liked it!
I love the Barney style explanations that means a crayon eater like me can understand it
Love the video,
Love the model,
Great job buddy,

nice explanation you just earned a new subscriber
happy new year by the way
Tha KS for watching
So will titanium stop valve float??
Less likely ....
It does not happen to such extrems the valve doesn't exactly follow the cam lobe but that doesn't mean that the cam will do a full turnaround the valve would get smashed by the Piston from underneath before that would happen ...
Valve floating Will make you loose power, puts stress on a stock spring will brake it than piston hits the valve, so it happens exactly how I said it..
@@vegasromaniac you missed my point everything you said is true except for the detail that the cam lobe will not be able to do a full 360 rotation and hit the valve again the valve floating is usually hapening within 15 degree of aditional opened time not a full cam rotation ............But OFC the takeaway is the same it s just that that it doesn´t happen to such extreme as a full 360 cam rotation
Best explanation on CZcams
Thanks for watching
Ypu explained it perferct!
Thanks
Very great example 👍🏻👍🏻
Thanks
Nicely explained, model really helped. Thank you😊
Cool Model
Gld you liked it
Does this only happen when changing valves and not springs with the valves
Yes , stronger springs helps with that
@@vegasromaniac I'm doing injection turbo and e-fuel kit on my 1995 f250 with the 7.3 in it and a guy told me to replace my string bc I don't want to float a valve but in not replacing any valves so it really doesn't make sense to me. Can you explain please
So u think this would cause retainers to crack? I think,my springs are just weak,they keep breaking retainers and buckets cant figure it out...valve on the tip where the keeper holds it is all worn out too but i replaced everything but springs i hope thats it ..what u think
Oh man, I have never seen retainers broken. That is new to me. I hope you got it right
@@vegasromaniac yea well mt clearance was on point timing also...no dragging in cam buckets only thing im thinking is floating the same ones keep cranking but not bending valves or anything ....maybe weak springs too
thank you sir
Good video , nothing more nothing less🗣
nice model and verry usfull exolination!!
Thanks
hey Vegas, so which oil are you using now? I saw your video on supertech mineral oil... so is that the regular mineral automotive cheap oil, non JASO ma? if it is the cheapest automotive mineral oil how long do you go beetween changes? i saw the video but did not quite get what kind of oil is that.. Thanks.
I use supertech 10w40, regular, changing oil every 20 to 40 hours.. Depends on the riding i do.. Aiming for 40 really
@@vegasromaniac so it is literally the cheapest possible mineral automotive oil? I am asking beacuse everyone swears that will destroy the engine beacuse its not synthetic, its automotive, the intervals are too long bla bla..
Maybe try linseed oil?
I have seen first hand stainless steel valves wear timing chain and the timing chain gear on the crankshaft. Broken timing chain guides . All kinds of problems running stainless steel valves.
Agreed
My 01 WR426 has about 250 hours on the stock internals (minus an 03 YZ450 exhaust cam and retarded timing) and it is still going strong. Stainless valves are stock on it. I wouldn't waste the money on ti valves for a bike that old but there's no doubt ti are better
@@nickchilds3104 I woukd not change stainless to ti if cones with ti,.. And vice versa
Nice man
how can i message you to talk abou it need help finding the titanium valve for my yz250f 2016
Ebay, or rocky mountain atv, find a chart order the one you need.. Type yz250f parts chart
Nice story, but start by beginning..please... Why changes people a titanium valve to a steel version??? reason is....?
If your bike comes with titanium use titanium if steel than let it be.. Steel
If it works, don't fix it. HAHA Ride safe my 2 wheel friends.
Yeah..
Go desmo float not possible
Nonsense. If you are a PRO rider that can take the bike on the limit, Titanium is best for you. IF you are a novice rider just out for fun, SS will just be as good as you won't find the limits of the valves anyway.
1st again lol
Dukecronic kachow
noooooooooo
Inside an engine is proper explanation Wood Is not
