In Reply To	Do you hear it at idle or all rpms? I only heard posted by MikeH(Twin GT35BB Incon Z) on May 23, 2003 at 10:57 PM
Message	is usually heard as the rpm is fluctuating. Just barley raising the rpm off idle than letting it go back to idle will make it knock. How ever a bad lifter can also react in the same way But, as the bearing gets worse you will start to hear it even when the rpm is kept at a constant value, say 2000 or 3000. YO FRANCE, STICK IT UP YOUR ASS!!! Fred 95 300TT SGP Stage..Who knows..lol Dynoed 539.4 RWHP, 481.2 Lbs. Torque Pump Gas @ 17 Lbs. of Boost NO NOS!! If you're 20 and a liberal, you're excused, you're naive. If you're 40 and a liberal, no excuse, you're just stupid!!!
