High pitched engine pinging noise
 

At the beginning and at 11~13 seconds there is this high pitched pinging sound, can anyone explain what it is ? i recentlly installed a stillen gen3 cai and had the battery disconnected, and also a slight rattly at 2k rpm (probably the intakes hitting the plastic wall)

Your video link isn't working. When you use the YOUTUBE tag, you just need the video ID (see bold portion of URL).



Sounded like normal VVEL chatter to me. It sounds different than it did before you installed the intakes?

Haha thnks for pointing that out , But yeah it sounds amplified, is the vvep chatter supposed to be like this ? *note that a high pitched continuous background whine are the fans in the parking lot, the sound that appears at 11~13 sec if u listen closely is the one (sounds like sonar pinging)

If the noise bothers you, try using an ester oil.

FSM might provide helpful hints...

I got a constant pinging/ringing in my head/ears :ugh2:

Try using Nissan Ester oil or Royal Purple Synthetic motor oil that will help reduce the noise.

I hate it when the voices in my head have a staff meeting. :shakes head: Now, I have a new voice in my head that every couple of days, says "Low Battery". One day, it's in my left ear, then a day or 2 later. It's in my right ear. :confused:
