IF my car were to have rod knock how would i know...would it make the knocking sound all the time even when the car is not moving or would it only make it while i drive and at certain rpms or would it be a constant knock the whole time?? plz let me know.

 

more then likely always here it. the sound will vary between rpm's. prolly should NOT drive it if you are hearing a knock.

 

 

you will hear it all the time and definetely should not drive it, you will end up causing a lot of damage....
