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!

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.

[jamesmeny]

You just answered exactly what my car has been doing for a while. Time to change the spark plugs! Thanks for the video!

[adiansbane]

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!'

[maryhoffman]

You have no idea how happy I am that I found you. Thank you for sharing your knowledge!

[IrAbynormal]

Thank you for uploading this video it's the most comprehensive coverage on what could cause a P0325 code available on YouTube. 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.

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!

Thank you for putting out your information on engina. I have a 2001 Chevy, Tahoe. And it just started knocking. I never have any time to work on it but your information. Help me to narrow it down. Thank you

[KingLess]

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.

[williamwhite]

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.

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 👍

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.

[oscarbolo]

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

[DcPichy]

[udayhomeful]

[chandamwila]

Thanks my mechanic.My Toyota Hiace 1rz engine had this problem recently and was fixed by correcting the ignition timing.The distributor was over advanced.thanks good video.

[dannyhuynh]

You would make a great mechanic teacher for a tech college. So thorough and easy to understand. 👍

[aboelsofalabed]

Honestly I like the way how you explain every thing thanks a lot man

[Ranger]

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
