can someone enlighten me on the subject of ping??? i have never heard it i dont think??/ is it that rod knocking noise, is it a miss noise?,what is it??? ive been working on cars for a long time now and i can honestly say i have never heard the noise a car makes when its pinging. can someone help me figure this out??

 

Grab a tin can, put some rocks in it, shake
That's about as close as I can think of.
It's not a tick, it's not a knock, it just sounds like a bunch of "ping"'s and usually occurs under heavy load (3/4 throttle or more). (FYI, PING = Pre-Ignition)

 

thanx

 

You will know when you hear it, trust me. It is not a pretty sound.

 

ping sounds just like the name implies. Light ping will literally sound like a metallic 'ping' thats actally a shock wave traveling tyhrough the engine from colliding flame fronts. If you listen closely, sometimes on a hot day in traffic with regular in the tank, you might be able to hear an occasional ping when you go to accelerate.

 

What causes it... how do you avoid it, or get rid of it?

 

Too much timing, overheating, too much compression. Most likely if you have it the timing is too high. Just back it down until it doesn't ping anymore.
