What Causes Engine Knock 

Dude woke up and decided to make the greatest, more concise video on engine knocking on RU-vid. Really good video

Good explanation and in a very short time. Thanks!

Always wanted this visual explanation! Well done sir. Thank you!

This video has helped me so much and understanding an engine, even though it was very little information. Thank you.❤

Thank you Mr Pacino

For anyone who is asking! Can this be fixed?!? Yes, I've replaced rod and main bearing on an 88 dodge ram and it ran just fine after I replaced the bearing.

This is rod knock, not engine knock. Engine knock is the air fuel mixutre igniting when it shouldn't. Usually, this is caused by too much cylinder pressure or not enough octane, and this causes a knocking or pinging sound. Many modern vehicles have knock sensors that can detect this and the ecm can retard ignition timing to prevent catastrophic engine failure.

Thanks a lot brother

This man is the opposite of a yapper, every word had meaning

Around how much would this cost to be replaced if so

I have a 2018 Camaro and replaced the engine because of engine knock and 2 months later today it started knocking again

Or could I possibly send u a video of mines I’m a dad just got this and my new job I loose this truck I loose a lot I’m trynna get to the bottom of this

I have a Mercedes B200 2008 that recommends octane 91 fuel and higher but I've been using the lower grade octane (85 or 88) since I bought the car in 2009. Is it good or bad? Should I switch to higher octane or its too late?

Is this a serious problem or could be repaired?pls tell me

Is this expensive to fix. Can i fix this myself under car remove oil pan?

My engine cut off cause of this & im trying to save it
