How to Easily Fix a Stuck Valve (Quick Fix)
Вставка

- Step by Step!
So today we're working on a Storm HG202B pressure washer, powered by a Honda GC160 5hp engine.
This engine was ran low on oil, which most likely lead to the engine running hot, resulting in a seized intake valve.
The intake valve seized in the downward (open) position, which allowed combustion to escape through the intake valve, and out of the air box.
The customer didn't want to spend a lot of money (thinking the engine was toast) and was hoping for a "quick fix" which is exactly what they got (same day repair).
Ideally, you'd want to remove the valve for inspection, make sure it isn't warped, do a leak down test to ensure the valve seat seals, then remove the valve and maybe even polish it with some emery paper (fine automotive sane paper).
However, on an OHV (over head valve) engine, you need to to remove the cylinder head to remove the valves.
This leads to more labor and need for replacement parts, as the cylinder head gasket would likely need to be replaced. Additionally, whenever you reinstall a cylinder head, the valve to rocker arm clearances would need to be adjusted, which leads to more time spent on the repair. (I.e. more cost for the customer).
At the end of the day, this pressure washer now starts 1st pull, runs smooth, and the pump works. Making this a fully functional pressure washer!

However, on an OHV (over head valve) engine, you need to to remove the cylinder head to remove the valves. In this case, you'd also have to disconnect the timing belt from the camshaft, this leads to more repair time when assembling due to the need for proper timing alignment.
This leads to more labor and need for replacement parts, as the cylinder head gasket would likely need to be replaced. Additionally, whenever you reinstall a cylinder head, the valve to rocker arm clearances would need to be adjusted, which leads to more time spent on the repair. (I.e. more cost for the customer).

Thanks for the tip of heating up the valve cover for removal. I've always had a problem with the ones with no gasket.
Can you make a video tutorial for all this ^^
My Briggs and Stratton v twin Intek 24 hp rider mower was turning over very oddly when trying to start. It would make a few reluctant revolutions then stop turning over and would not start. I decided to check the valve adjustment and found I had 3 bent push rods and the other broken in two. I noticed the exhaust valve springs on both cylinders would not depress more than about 1/2 inch. I tried gently tapping the valve with a hammer but no luck. Was thinking the engine might be toast so went to google and found your video. Surprisingly, you advised doing the same thing. So with renewed confidence, I tried tapping with a hammer again, only this time with more force. It worked great. I didn't need to do anymore than that and after installing new push rods, the mower ran like new. So, wanted to say thank you for taking the time to post this video. I'll be checking the valves every year now.
Great fix. Those are good engines and keeping them running for cheap is a good deal for the customer, who will use it today and let it sit 12 months until they use it again
Yes exactly, best to keep oil in them and run premium fuel with no ethanol if they can get it. Thanks for watching!
Same Honda engine and it was this simple.
Did the pressure test with my thumb - no pressure
Off with the cover, no movement on the intake valve, rocker arm off……tap,tap,tap…valve free..gave it some exercise
Reassemble and started right up
Thank you for the well described video
Thank you
I learned several handy tips in this video, and I have been repairing small engines for myself and neighbours for decades. Thanks for posting.
Thanks for watching!
I enjoy watching how others fix things and I turned wrench’s for 57 years and retired, still working on small engines and no v16 for me
Very good repair. Easy fix right there for the no compression and stuck valve 🔨
Thanks for your support sir and you keep posting your great videos also, i really enjoy them.
@@waynestefinashen239 thank you mr.wayne sir I appreciate that.
simple and detailed, good teacher
I usually just leave the valve cover on and use a 3 lb sledge 😉
Great video buddy
They bend too easily and takes more time to straighten them out than the time it takes to heat and release the cover when they have used RTV gasket maker.
Little tap with a soft blow mallet does the trick after heating them with the heat gun!
Good video,I've got a stuck intake on horizontal Briggs flathead,you are the man!Keep up the good work!
Thanks Jungle Bob, maybe those are a bit easier, you can remove the valve and polish it up, clean up the valve guide without having to remove the timing belt like this one!
Nice and simple fix. Thanks for the video.
Thanks for watching!
1:38 Yes, it is very important to note that the piston reciprocates if it is backfiring out of the carburetor. That's how you know it's a piston.
Great job and customer is happy. Cheers
Thanks for watching!
Excellent. Thank you 👍
Great tip for the stuck valve. Thanks👍👍
Worked great, thanks for watching!
Love all the tips. Gave me the confidence to tear into my daughter Husqvarna rider and get it running
Thanks for watching, glad the videos help!
Yo yo Jake.. looks it's it's got some hours on the clock.. yeah they do break a flywheel key on these.. still good for you getting it back to them in the same day
They were happy, thanks for watching Mick!
A quick and easy fix it is and another happy customer leaves EP with running equipment in hand for a reasonable repair cost. Another good one boss and i am thinking about doing an Eliminator Treasure Hunt when you film the sticker shout out video. What do you think?
Good idea!!
Sounds like a good time, thanks for watching!
Had a stuck intake valve on my KLR650 - i believe it was stuck due to the massive amount of ethanol gunk that built up over the years.
Sprayed carb cleaner into the vacuum line while it was running for a few minutes and resolved the issue.
So very common on these engines
You've got a gummed up Prime Minister too. A plastic mallet might be the cure also!
Nice quick fix!
Love these quick fixes every now and then, thanks for watching!
Nice work keep up the good videos
Thanks Henry, love a quick fix every now and then!
will try the same on my dirt bike tomorrow :)
Good video!
Thanks Vernon!
That engine looks like a over head cam style of engine I see it has a timing belt I could be wrong about that matter young man 😎
Yes OHV with timing belt, good engines, just don't run them low on oil!
@@EliminatorPerformance I heard that young man 😎👍 thanks for the heart also
It works on most of them 😊
Nice job and explanation Jake, thanks for the video.
Thanks for watching!
Giving the Chubby Butcher the spare sticker you had sent me, hope that is ok with you. Have a good day sir!
Thanks Mr Wayne, that’ll be great. 🙂👍🏼
He may not want to trash his board up with mine though. 🤣
Did you get to see your shoutout on the Chubby Butcher? Also hope your family is ok hear there is lots of flooding in Mississippi
Good day Jake Hope everything is healthy
Merry Christmas & happy new yr. Thanks
I did not know you could use heat to soften the sealant to remove the valve cover. Im gonna try that next time I have to remove one.
Good day Jake Nice video. I have roto tiller front tine flat head briggs 5 hp, the intake sticks , how would u fix that? Thanks
Probably remove the valve and take some Emery paper to it, maybe polish the valve guide too!
I'm getting a backfire in the air intake box but my valves move freely. Any idea?
I tried your suggestion. I even let it sock in carb cleaner for 3 days. It still will not move. Have you done a video on a value replacement on this still of Honda Engine?
Good
Thanks Philippe!
For you do it yourself learners, water should be connected to the pump when starting.
Question:
Kohler courage 17.
Valve sticking like this so i pull it apart and clean it up real good and it works great for the summer. Go to start it up for the new season and the valve has done it again. Should i just replace the head and be done because im reading somewhere that i may have a leaky valve thats causing excessive heat and its burning the oil around the valve shaft.
Thoughts?
Kohler's are known for that on some of the courage models. The valve guide has likely shifted too. Unfortunately you'll have no other option then to buy a cylinder head and the valves and springs, the rest of the stuff you can likely reuse (like rocker arms adjusters etc...) unfortunately they don't sell them as assembled heads anymore!
@@EliminatorPerformance one more question.... I inherited a low hour craftsman with a briggs and stratton 20 hp turbo cool ic platinum engine.
Would that be a direct fit replacement or not worth the trouble? I'm mechanically inclined so it's not an issue but I just wonder if it's just better to fix what I have and sell it or replace the whole engine and be done.
Change oil regularly folks 😊
You forgot to mention how hard it is to get the valve cover off LOL! Hondas are a pain with that sealant from the factory.
Yea the heat gun really helps with that!
Those Hondas are terrible about sticking intake valves. Especially if old gas is used. Use some ATF to clear some of the carbon that is causing 8t to stick when you work if free.
Great video
I have a similar problem. My husqvana push mower with a Honda motor start to give me some problems. The push cord is kicking back big time. I took the flywheel out anti inspected the key and it’s fine, so I drained the oil and inspected the spring valve and I noticed the left side does not move when I turn the motor. Will that cause the kick back???
I’ve got a stuck exhaust on a B&S. With the head off, I can tap it closed with a hammer, and then turn the flywheel by hand to nudge it open again, with loud squeaking noises as I go. But it stays open. It takes the hammer tap to close it again. I’ve done this 10+ times.. it does not seem to be getting any looser. I’ve sprayed penetrating lub on the valve shaft before I tap it down each time.
Any suggestions? Should I just keep doing this? Even if I removed the retaining clip, I won’t be able pull the valve out. I can’t spin it with my hands all.
The valve guide is most likely worn, or the valve stem itself is warped and could be getting hung up. Even a few thousandths of an inch is all it really takes on these. You may have to remove the head and replace the valve guide.
@@EliminatorPerformance Thanks for the reply, and thanks for your videos! I've released the spring. I can get the valve out about 1" then it seizes and will not come out further. Even with a lot of force. Its like it gets tighter the more it comes up. I can tap it back down and raise to the same level..but not past about 1". Are there any specialized valve extractor tools out there? I’ve searched, but have not found anything. I’ll never put this valve back in if I get it out.. so chewing up the valve head is not a concern at this point.
How’s it going Eliminators? I need some help. I’ve got a Honda clone push mower. Exact same valve spring retainers but I can’t get the intake retainer off. I don’t have a special tool, just using the locking pliers trick. Does anyone know another method? I’m hoping to avoid buying a compression tool, they’re expensive here. Thanks!
I have the same machine. Mine is a 2005 and I always changed the oil with synthetic, also ran ethanol free gas. Never had an issue until I was using it one day in 2014. It had been running fine. I was washing a large SUV and shut the motor down so I could mop it. When I went to start it back up, the pull start was super loose and it wouldn't start. I really love the machine, it still looks brand new and was well cared for. Any suggestions as to what the culprit might be?
I heard these GC Hondas have oiling issues to the top valves and this is why they seize valves. I guess it's a common issue, although this is the 1st one I've had come in that's had this issue
Do you think it’s worth popping the cover off and verifying before I junk it?
Thanks!
Donald thanks for the support we appreciate it greatly and hope that our videos have made it easier for you to fix or service your own equipment and save time doing it. Thanks for being an awesome subscriber.
Thanks for the support Donald!
Could they have cheaped out on the frame more without making it out of plastic?
Thank you !
Nice upload 👌
Curious what would happen if you don't put that black silicon stuff on the cover and run it?
Some oil could leak
My piston is moving down then up. Not up then down. Now what?
Nice one samlol23 they normally do that when you rotate the flywheel in the opposite direction eh?
Needs more strokes! Thanks for watching!
What's the reasons for valves getting stuck?
@@MrPedro2213 overheating
@@EliminatorPerformance can contaminated fuel be a cause?
question fir yiu i have a dynamark 8-36 and the starter turns the thing on top and it makes a clanking noise but it wont turn engine its making spark and is not locked up and has fuel and air so what can be causing this please let me know im 14 and i love fixxing small engines and i cant figure it out plus i dont got my dad and my moms not good with this stuff lol
There are a number of reasons your engine will not start: 1. It may not have enough compression 2. Intake or exhaust valves may be stuck in the open position 3. The flywheel key may be sheared making timing of the spark off position 4. The spark may be weak and not igniting the fuel 5. Fuel may not be getting to the spark 6. The spark plug may be incorrect or bad especially if it is an aftermarket Torch. There are many reasons, i would suggest you subscribe and watch as many small engine repair channels as possible and cut a few lawns to generate some cash to invest in tools. Also ask for tools for Xmas i think you just may make one heck of a small engine repair technician buddy.
Is it ok to run without water
it doesn't hurt it you do it for a short time, but if running for long periods of time, the water should be hooked up. These pumps have oil in them, which does lubricate them.
Many of the operators manuals for pressure washers will say not to run the engine without the water hooked up and while running do not run without engaging the gun trigger to engage the water gun for more than 2 minutes at a time. Some also say to start with the gun trigger engaged while it is not necessary on others. When asked this question by customers we always tell them to refer to their owners manual or if they do not have one we check for one online for them. We have tested many like Jake did for short periods of time to ensure the engine runs without damage but we also have hoses and wands to hook up to test under load conditions.
👍👍👍
Thanks Pete!
It’s a little trouble to remove water pump but better than running it dry and destroy a pump
Also pump may allready bad and they will sue you for new one
After many years, I've never noticed a pump go bad just by running it dry for a very short period of time here and there. My own generac pressure washer would be a good example. I've never been sued either lol
I only put 10w 30 sny oil in them now
2:30 A stuck exhaust valve would not make a backfire through the carb.
At 2:30 I was referring to compression at the spark plug hole, if there's no compression but the piston and rings are good, you could have compression escaping through the intake or exhaust valve. A leak down test would prove that, or just pull the ohv cover as I did in this video.
Most likely bad gas
Thank you !
