I have slight knocking noise
on my 3gm30
It is less obvious in certain rpms.
What ca be the cause of this?
I have two theories.
1 a half bad injector
2 Could a worn con rod bearing cause this noise
Or am I just paranoid.
is it normal with "diesel knocking sound"
I know that a diesel
sounds different than a gasoline engine
, but what is ok?
The noise is worse on start and cold engine
Is there any sound recording of a good running gm somewhere?
Thanks. Hope you do not find my questions to weird.
