That, I also believe and, in fact, have "tuned" my engines many times to just remove enough "ping" that I couldn't hear it.<br />

I'm already topped out on pump gas. I'm bordered on maximum timing, and it only pings when I'm lugging it, which I<br />
define as hard acceleration coming out of a turn at around 2000rpm in too low of a gear. at higher engine speeds, it<br />
doesn't ping. this leads me to believe it's a combination of timing and my driving style. you've always said that<br />
performance & economy are not necessarily bed partners. I'll do you one better and go as far as to say that<br />
performance and longevity are not bed partners. if I continue to drive this engine on <strong>the</strong> border, allowing pinging on<br />
occasion, I think I'll end up toasting <strong>the</strong> rings from <strong>the</strong> excessive heat over time, for a second time. anyway, I'm<br />
about to just call it and say this is <strong>the</strong> best I can do, and that I can ei<strong>the</strong>r have driveability and longevity while<br />
sacrificing a negligible amount of power, or go <strong>the</strong> o<strong>the</strong>r route...<br />
I have also experienced <strong>the</strong> hard ping under lugging or low RPM load. This ping is <strong>the</strong> one that seems to sound <strong>the</strong> loudest and<br />
most damaging. Although ping at higher RPMs is probably just as damaging.<br />

<strong>the</strong> way I took his final statement about how an engine should ping was not in saying that you should actually drive it<br />
pinging, but to downshift so that it does not. this is <strong>the</strong> part I find applying to my situation. maybe this is that "certain<br />
condition" that my girlfriend's bro<strong>the</strong>r in-law was talking about, though his take was that it's okay.<br />
Driving <strong>the</strong> engine "pinging" any time is not good.. period.<br />

anyway, most of this post was about what <strong>the</strong> causes are, <strong>the</strong>n a statement about how and why to fix <strong>the</strong> problem.<br />
Yes, you see his multiple contridictions.<br />

no sir, I'm not going to try to convince you that pinging is okay. I fully respect your knowledge and experience even<br />
though you're humble about it, and I'm with you; I don't think it's okay under any situation and is simply and<br />
indication that something's off, ei<strong>the</strong>r timing, carbon, lean mixture or you're just plain driving wrong.<br />
OK, we agree that "pinging" is NOT "OK" and it indicates a problem, it can damage an engine, and it also reduces power.<br />
Quote:<br />
I'd like to find some good, reputable reading on <strong>the</strong> long term effects of pinging, though I'm pretty sure that running<br />
my last engine too lean is what burned up my rings.<br />
I think you've answered your own quest for "reputable reading".... you done better, you've experienced it for yourself.<br />
Hey...Guess what I bought Sunday?????<br />
