Default tapping noise at idle

I think if it was an oil pressure issue you would possibly have advance and retard issue for the intake cam since they are driven by oil pressure.



Hope this helps, I can only do so much over the interwebs.


That might explain the fuel odors I’ve been smelling then if it is the purge valve lol


Just to clarify though, is it the pcv valves at the front if the engine you’re talking about or the actual purge valve on the canister? Cause i replaced pcv with new oem like a month ago
