Good evening,
I have a 2003 Honda CRV EX 4awd and I noticed between 10 to 20 mph I heat a knocking or pinging noise from either the valves or something in the top of the engine. I'm a 100% sure its from the engine and it only happening in the lower speeds. When I get to 27 - 30 mph it goes away. Has anyone else have had this same noise issue? Here is a list of what I did to isolate this issue.
(1) I replaced all of the plugs. Same noise.
(2) used 93 / 92/ 91 octane gas. Did not make a difference same noise.
(3) Replaced the spark plug seals. Not sure if it was oil getting into the engine. No difference.
(4) pcv changed.

Please anyone help.
Thank you in advance.
