Made the 2.5hr drive back to my parents for thanksgiving and I noticed an odd droning coming from the motor. Sounded kinda like maybe one of the intake valves has a more distinct close than the others when listening to the intake tube. I'm almost wondering if one of my lifters collapsed while on the interstate and it bent a pushrod. I honestly don't know. I noticed on a drive today it was a bit down on power but it doesn't have a full out missfire like I've noticed in the past when I've bent pushrods. I changed the fuel filter thinking maybe it wasn't allowing enough fuel to get to the IP causing it to retard timing or something but it didn't really help any. Any other ideas other than pulling the valve covers and checking it out? Like I said it idles good other than the droning vibration.
