😂YES! I definitely replayed it seven times or more times! and then turned on the captions and he definitely says Donald Trump's and the captions say it too!?! What is he trying to say? Or is he literally making a joke cuz I'm trying to learn lol And I don't think Donald Trump had anything to do with the engine knocking or not 😂🤷♂️
Dear Ratchets, I honestly don't know what I'd be doing with my car if it wasn't for you. You've helped me so much over the last 5-10 years, your videos are always comprehensive; understandable and often funny. I've undertaken many DIY car repairs confidentially and successfully thanks to you, including but not limited to, spray-painting (re-clearing; blending; sanding/polishing and so on). Thanks so much , keep up the amazing work, we all appreciate you more than words could ever describe!
Its way cheaper to replace the engine than to rebuild it. The down side to this is that you dont know what problems the used engine might have. Rebuilding an engine will let you know everyting is ok.
Strange thing about running a lean condition is, it ends up using more fuel. You'd think if it's running lean it'd be less, however you end up mashing the throttle open more to compensate for the lack of power and in turn makes it use more fuel.
Most other channels just blame the lean mixture or the low octane fuel but you've done a great job putting together a comprehensive list of causes that contribute to engine knocking.
Very informative. I feel much more capable of tracking down my ping in my Ford 4.2. I just bought it and I'm not sure if the plugs have ever been changed. 128,000 miles. But I will go through this process. Thank you. Donald Trump is the greatest President in American history.
I got a 2013 Chevrolet impala and with direct injection i had a pinging noise when i accelerated, i added that Berryman B-12 AND it really helped that pinging. I assume i had carbon build up . Very interesting video 👍
This video was super informational and explained in very easy to understand and terms! Thank you for explaining so comprehensively what can cause engine knock, I feel much more confident going into the mechanic now instead of just driving up and saying 'there is a concerning noise, fix it!'
Would be great if all engine knock problems were as simple as old plugs. Good list of possible causes. For the purpose of evaluating fuel trims for rich or lean condition, it should be check at varied engine speeds and loads. I recently switched from 87 octane in my Ecotec, GDI engine to 91 Octane, Top Tier fuel and it significantly reduced my positive long term fuel trims. Before it would run nearly 10 percent, but now it is 2-3, with STFT fluctuating between -2 and + 2. This is consistent through all engine loads.
donald-trumps the ignition timing...good one and great videos aside from trump as well also is there any way to 'revive' a car's performance without spending a ton of money? (due to age)
I don't think I'm an expert by any means; however, there are always ways to do thing less precise to pinch a penny. The question is more of, is it worth it. For example: Block-sanding a head and block for a blown head gasket instead of having it milled. I personally doubt there is a noticeable performance difference for daily commuters, but, due to the larger imperfections, my logical side doesn't doubt -some- power loss on the high end side. Mind you, block-sanding is a f*** ton more labor on your part, imho. Though I can prove neither of these claims either way. Just can't afford to, nor have the time, to find 2 engines of the same type with identical starting power outputs; both with blown head-gaskets only; have one milled and block sand the other; then rebuild and dyno. Even then, I would be willing to bet the power loss delta would be so minimal, you wouldn't really know which was which on paper.
Donald Trump's the timing. You can't mix politics with a subject that the majority of people have questions about and will probably watch you video. Unsubscribed
Thanks for the video. I add a couple bottles of Gumout with PEA to my vehicles gasoline occasionally to help clean up the intake valves and combustion chamber. I also use it in my old carbed motorcycles and it does a good job helping to keep the carbs from plugging up. I also use it in the gas of my 2 stroke FI boat motor where it solved an engine miss. I also mix some with the gas in all of my gas powered lawn tools to keep the carbs clean. Chevron Techron does a good job too I've heard.
The fellow doing these videos is magnificent. I believe I've learned more, via an easier fashion, regarding engines from him than from anyone else. That's not to say that there aren't a lot of good fellows on the innerweb putting out good stuff, I mean to say that this fellow is just that much better. Great presentation! Thank you so much for teaching me stuff for free!
Great video. It explain and or answered my questions. I've looked for videos about knocking and couldn't find any explaining or showing or even detailing it to me like this. Great video.
But what causes engine knock at startup that last only 2 to 3 seconds then smoothes out and everything quite .. especially happens at cold startups when the cars been sitting for hour or 2 .
Thanks for the video! Based on what I understand here with my Toyota v6 I'm going to simply try higher octane fuel as a 'dumb' diagnostic to see if it helps. Of course this doesn't fix the problem, but gives me some time before I have to worry about fixing it. Then I'll probably do some Seafoam, easy to do and not a whole lot of effort (possibly will clean out carbon.) Then after I've wasted my time and gas money on that I'll go after the real problem which I'll bet is probably EGR, spark plugs, or lean fuel.
Love your videos! That scanner definitely is not for the everyday joe 😂 Expensive!! That’s what ya need to do all the mechanics stuff though. The cheap ones will not do all the stuff this one will.
My engine had 300k on it. Just bought it. It didnt knock when i bought it but today i changed the oil and turned it on. It knocked, and knocked in nuetral, but when i drove it stopped then after driving around the block the knock stopped. Update I think its an EGR problem or something. Like a diaphragm that isnt working properly till it heats up and it may be messing with the o2 sensor bank 1 Update pt.2 The bank 1 sensor one replaced from a junker, it killed the code, the deep wierd knocking sound was coming from a rectangular unit behind the EGR valve. It had lost all of its screws and blown open. I bailing wire tied it back together and now have an egr code but the sound stopped
I had to rewind and rewatch a few times to confirm what I heard but OMG the joke about the computer retarding the timing was hilarious. I screamed in laughter 😂😂😂
My car make sound like trrrrrr trrrrr tarrr with acceleration. And check light for knock sensor on off. I have changed 3 knock sensor it works for one day then again that problem. When check light turned off there is no knocking when on then again that sound. Plz help me
Been having issues on my new to me truck a Silverado with 133k keeps throwing a knock sensor code already changed the maf which was at 1ish g/s at idle . Cleaned the intake manifold and I’m going to change the spark plugs next hopefully that was my issue 😢
I have a 2006 Chrysler 300C 5.7 that is heavily modded (2009+ cylinder heads, 2009+ intake manifold, headers, cam, MDS/EGR delete) currently untuned. It only runs if the MAP sensor is unhooked at startup. You can plug MAP back in while its running, but then I hear a knocking/pinging noise. I'm guessing due to detonation. Between all the mods and EGR not able to be used (there's no way to hook it up and make it work with the new heads) that's probably why I heard that sound. It went away when I unhooked the MAP sensor again. Plus the heads also increase compression to about 12:1 or so. Its probably a combination of several factors, Fuel/Air/EGR. I just wish my tuner would stop dicking around and send me my tune.
if detonation sound is caused by wave fronts colliding then why preignition sounds the same? in cars with two spark plugs per cylinder why don’t the wave fronts make any knocking sound. self ignition after soark ignition causes the mixture to burn faster amd messes up timing but retarding timing helps.
Hi friend. I believe what you are trying to describe is called pre-ignition which is different from detonation. Pre-ignition is when you have a secondary source oh heat such as carbon deposit that would cause the fuel and air mix to ignite while the spark plug is off. Detonation is when you have two or more pockets of compressed air and gas mix that would ignite at the same time within the same cylinder. Since the two explosion have and fight for the limited space their collision will cause what’s known as a knock.
My car wont start and i dont hear anything when i turn the key the right pressison and i tried the other pressison i did not hear anything its probley from the engine, Sparkplug and Battery And Its Shows That I Have 0 Fuel And The Arrow Form The Fuel It Shows Emety My Dad All Ways Put The Diesel Oil Beacuse This Is The Oil For My Car But When I Turn The Key Over The Correct Pressison You Can't Hear The Engine It Wont Start ?!?!?!?!? I Am Confushin!!!!!
My car only start knocking when I put it on any gear and push the accelerator and when I release the accelerator then there is no any knocking noise, At idle condition doesn't matter how much I accelerate it remains smooth, problem occurs when I accelerate with gear in running condition and there's no noise from transmission but only from engine when I accelerate to run the car with gear
I thought detonation happened before the ECM or distributor commanded spark ignition. Not after. That’s why it’s so bad. Because the piston position is still a long way away from being where it needs to be and the explosion of fuel tries to send it back the wrong way. Another term used to be pre-ignition. And advanced timing also causes it.
question..my car have a knocking issue at high RPM(engine check is on)specially if i ran my car at the highway.. ,but on low RPM it's fine..any suggestion what is the problem with my car..please help,thanks🙏

hi i have a 2008 ford fiesta 1.4 tdci.. every time i press the gas pedal down, there is a noticeable single knock. this happens in 1st, 2nd and 3rd gears, not in 4th or 5th. it isn't just when changing gears, it's every time the gas pedal is pressed. took it to 2 mechanics, and after almost a week at each place, neither have any clue what it is. they said it sounds like it's coming from behind the dashboard. any ideas?
Does spark plug knock goes away with acceleration or it will still be there? Cause I don't know how it sound like. Do you have a video of the sound when accelerating?
any body help puegeot 207 1.4 petrol 2011 car runs beutiful for 10 or 15 minutes and then a loud nock will start and continue, and the same thing hapens all the time.after letting it cool down any ideas anyone / /.
I am your old subscriber , plz tell about cases of 1 or half second knocking or rattling sound on engine startup. It is suzuki swift 2012 , 1.3 non vvti engine, my radiator become empty few days ago for few min, but heat gaige not goes up. So i suddenly stop car and replace radiator and car was ok, after 10 days this rattling sound start comming on cold start up for just 1 or half second.
I replaced my rocker box gaskets and new spark plugs and gaskets 4 days later I start the engine up the engine was knocking 2 times then it stopped if I go really fast you hear it knocking then I slow down it's ok every time I start it I hear it knocking that would be something about the spark plugs, can you let me know please or someone. I will need to take off my inner take manifold and I don't want to do that again it sounds like I need to take it off
that was a total subliminal message about 5:42...I heard it...I had to replay it several times but im sure it said Donald Trumps ignition timing? Im reading other comments and I know they know that I know what I heard...very cool.....lol
Good diagnosis and remedy. Too bad you can't cook. But someday I can teach you. But I'm busy inventing a 20ft pry bar to remove the balancer off a Honda accord.
Dude you are the Best. Excellent teaching. Now i have a more detailed idea about what to check in my car that is knocking. I realiza i never change the spark plugs. Easy solution. Thanks
Guys I need help I have a 2004 mustang and sounds like I have a rod knock cause the engine knocks when it runs but I think I could have a head gasket problem cause when it drives the coolent boils and over heats
Are you located in San Diego? Please, I’m having a hard time to diagnose the knock in my engine. Let me know how to gent in touch with you the get an estimate for a diagnose. I live in Irvine so I could drive down to you.
I'm trying to determine if my knock is from this or my flex plate/torque... My knocking mellows out when I put the truck in neutral... But when I'm idling at lights,etc it's really loud. Thoughts?
I have a really bad knocking noise in my 2009 dodge caliber inside my motor and my oiled was over filled pass the line by like quarter and oil was leaking on the side where the fan belt at …..
what if you hear a slight knock rattle ping when driving but not when parked. my van only has 9k miles and the sound is ever so light. ua-cam.com/video/BS1489q8b3s/v-deo.html

What cause to lost power on a 2003 ford ranger 3.0 liter. the warmer it get the less power. No codes. I have check everything i can think of need help.
I enjoyed the video, but if I'd been diagnosing that fault, pretty much the first thing I'd have done is pull out those plugs and had a look at them, but that would have made a very short video.
Thank you for uploading this video it's the most comprehensive coverage on what could cause a P0325 code available on UA-cam. I recently had my head gasket replaced on my 2005 honda civic lx special edition. Three days after getting it back I'm getting a P0325 code thanks to you I at least have some steps to take before I spen a ton more money.
Yeah, great video. He obviously meant 'it trumps the ignition timing' or 'overpowers the ignition timeing'. Why would a trump supporter even be mad at this? Lol?

Its way cheaper to replace the engine than to rebuild it. The down side to this is that you dont know what problems the used engine might have. Rebuilding an engine will let you know everyting is ok.
Change all of the sensors while doing it.

Strange thing about running a lean condition is, it ends up using more fuel. You'd think if it's running lean it'd be less, however you end up mashing the throttle open more to compensate for the lack of power and in turn makes it use more fuel.
Was thinking about that just now!
very impressed thanks man u look tired tho, get some rest big brugh thanks for the links,yr great.
Most other channels just blame the lean mixture or the low octane fuel but you've done a great job putting together a comprehensive list of causes that contribute to engine knocking.
Clintoning of the knock sensor would be devastating
If you're using a private email sensor, there could be some knock.
What about Urmamasnuking lil Brain brandon ?
Or the spark plugs. They gotta stay dry
How do you not have a before footage of the engine knock, how are we supposed to fully understand what is sounds like. This video is not good

You can check a knock sensor by taking a hammer and tapping on the intake manifold if the motor stumbles for a second the knock sensor is working

that was a total subliminal message about 5:42...I heard it...I had to replay it several times but im sure it said Donald Trumps ignition timing? Im reading other comments and I know they know that I know what I heard...very cool.....lol
Good diagnosis and remedy. Too bad you can't cook. But someday I can teach you. But I'm busy inventing a 20ft pry bar to remove the balancer off a Honda accord.
Dude you are the Best. Excellent teaching. Now i have a more detailed idea about what to check in my car that is knocking. I realiza i never change the spark plugs. Easy solution. Thanks
Uh- 15 degrees BTDC is more advanced than 5 degrees - that’s not over advancing that’s regarding timing
Where are you located so I can take my car to yiu! I’ve done everything and nothing fixes. 23k miles 15ZL1 Camaro
Guys I need help I have a 2004 mustang and sounds like I have a rod knock cause the engine knocks when it runs but I think I could have a head gasket problem cause when it drives the coolent boils and over heats
Are you located in San Diego? Please, I’m having a hard time to diagnose the knock in my engine. Let me know how to gent in touch with you the get an estimate for a diagnose. I live in Irvine so I could drive down to you.
As a partial Trump supporter, I still found that funny. Well executed. Other than that, thanks for the vid, great and helpful info as always.
One word: alcohol. Lots of alcohol.
Discretesignals Have you ever run alcohol in an engine? The only ratio you need to know is "a shitload to 1".
177SCmaro sorry I accidentally responded in the wrong place
I'm trying to determine if my knock is from this or my flex plate/torque...
My knocking mellows out when I put the truck in neutral... But when I'm idling at lights,etc it's really loud. Thoughts?
Ever figure out what it was ?
I have a really bad knocking noise in my 2009 dodge caliber inside my motor and my oiled was over filled pass the line by like quarter and oil was leaking on the side where the fan belt at …..
Well apparently Donald Trump can fix more than the economy; He can also fix your engine knocking too!!! Lol 😂
what if you hear a slight knock rattle ping when driving but not when parked. my van only has 9k miles and the sound is ever so light. ua-cam.com/video/BS1489q8b3s/v-deo.html
Ty for the info! I'm gonna go to school for auto engineering! This helps a lot! Please make more diagnostic videos! Have a blessed day:)
hey you didnt cover rod & bearing knocks
My prius gen3 is knocking for 5-10 seconds when cold start? and it won't knock in evening when is hot day. any suggestions?
All the negatives or thumbs down are from non-tech / techs, looking at how to repair a ranger in their bay, and mad that you are giving techy secrets out lol... They can't make money on this repair now because you perfectly explained how to repair it.... 🙂👍 Whos the man....Youdaman
No, all the negative thumbs down are from Trump supporters who got their feelings hurt over his ignition timing joke.
@@supersabrosinho 😆 Trump Supporters are not fazed... Only Kevin's and Karen's
How can you diagnoses other causes of knocking, like rods?
What cause to lost power on a 2003 ford ranger 3.0 liter. the warmer it get the less power. No codes. I have check everything i can think of need help.
Trump 2024.
Many Thanks! Except I was looking forward to hearing what the knocking sounds like.
Love the Donald Trump joke you threw in there. Keep them up. And the videos of course
91 octanes? dafuq is that? normal gas is 95 and premium is 98 where do you get those 91? from an old scooter?
I enjoyed the video, but if I'd been diagnosing that fault, pretty much the first thing I'd have done is pull out those plugs and had a look at them, but that would have made a very short video.
Tonyv1951 disagree, other people might be experiencing other issues resulting in the same problem. Video was very informative. 👍🏼
Over advanced timing, carbon build up, lean air fuel mixture and hotter running engine cause pre ignition.
Hahahaha retards the timing!!!!! Well done friend I’m dying
Thank you for uploading this video it's the most comprehensive coverage on what could cause a P0325 code available on UA-cam. I recently had my head gasket replaced on my 2005 honda civic lx special edition. Three days after getting it back I'm getting a P0325 code thanks to you I at least have some steps to take before I spen a ton more money.
a bad Knock sensor Donald trumps it!! 😂
👌
👋🇬🇧👋🇪🇺😥
lol uhh "...Donald Trump's the ignition timing"? Almost didn't catch that one.
Trump supporters feel some type of way about this video 😂😂😂😂
Yeah, great video. He obviously meant 'it trumps the ignition timing' or 'overpowers the ignition timeing'. Why would a trump supporter even be mad at this? Lol?
Brotha To The Night I’m a trump supporter,maybe you wanna elaborate because that joke went over my head
It doesn't bother me
I do see a lot of triggered pussies whining in the comment section though
Well I'm feeling a tad hungry, and it's a few degrees too warm in here but otherwise I'm good thanks ;P
This video is fantastic. Watch and learn all the stuff from Ratchets and Wrenches channel and you'll be a damn good mechanic, or at least you'll able to work on your own car. The best quality explanations on the subject. I really need to get that scanner. ;p
Hey like your show the phrase Donald Trump did you come up with that or is it been an auto World for sometime already
