Sometimes. It depends on what is causing the knocking.
friend
start staying naked while you are in your room. they will probably start knocking after they walk in after a few times.
I get knocking & ping noise coming from the fuel injectors
by stepping on the remote or knocking down the set!
by passing the ball back and not droping it
no, change your spark plugs
threaten them by saying "I'll tell if you do it ." if he keeps doing it then tell. he will get in trouble. he will magically stop.
Try buying a higher grade of fuel first. Some vehicles require more octane to stop them from knocking. You might also consider putting in some injector cleaner with the first upgrade of fuel to see if that helps and cleans out the injectors.
Learn how to catch the ball... It's not that hard, it honestly isn't.
A higher octane gas or an after market octane booster. But, if your car/truck is knocking, then something is wrong, either your timing is too far advanced or something more in depth..
Sounds like your lifters are bad and might need ajusted or changed, it could be your cam not looping.
