Re: What does Ping sound like?
Theres a product out there called seafoam, can be found at lots of auto
stores, that the people on the Nissan Z message forums swear by to get rid
of carbon buildup and it "can" smoke like something else while doing the
treatment (do it at night if your concerned about the neighbors calling the
fire department).
I tried it in on my Z and the first treatment sent plumes of smoke into the
neighbors open garage up on the hill, he also happens to be the local
sherriff in my small town, but he didnt complain about it.
The second treatement yielded much less smoke, did it solve my pinging
problems in my Z, Not a Chance! That would have been too easy.
As for knocking, I dont think knocking at it's early stages sounds like a
coffee can full of marbles but more like what the name implies a knock, like
someone knocking on your door. I had a knock in my Z's lower end and
finally had to replace the motor. The tech thinks it was the piston rod
connections being loose causing the knock, I didnt bother to tear down the
motor as it was cheaper for my Z to just buy a jdm import used motor from
japan.
Good Luck,

Knock as I'm describing it is a combustion related noise, it's basically
fuel exploding too early. Other things can knock (rod knock) and even
some "knock" can be created if you drive a knocking/pinging engine hard
enough (i.e. break it).

Hmmm... I don't know how one could possibly detect this. After I
crank up Eminem on the stereo I can't hear any engine sounds
whatsoever. ;-)
