....this might change your mind. Pulled my upper off for a P&P this afternoon. It's largely in good shape, except for the #6 long runner. Check the last pic. This is from an early-year 2000, so it's got the hideously-overactive PCV (aka "turbo-suck"). Nothing really spectacular, just thought you folks might wanna see some pics. Surprisingly, the #6 plug was actually pretty clean, not fouled at all.
