Driving around last night and noticed a fast "ticking" sound coming
from my engine compartment. Not audible from the inside of the car. Popped the
hood and it seems as though the side of the engine closest to the firewall is
where the sound is coming from. Very loud, lots of ticking/tapping/rattling. I'm
thinking that all the valves in the rear bank are tapping/going bad??? That
sound right or does that not make sense at all? Now it "kind of"
sounds like a diesel, but not altogether. There's no loss of power, seems to
running smoothly, no stalling, no leaks, only mod done in the engine is a
Is this the beginning of a cam failure? Any thoughts? I have 6,000 mi left on my ESP. I hope that if it goes, it goes before then!
