Yup - change engines! :lol:
Seriously, I hated that sound. Stockfish told me the valvetrain tapping/ticking was just the way it runs, but it always unnerved me.I believe it's just due to the design of the valve seats and such... but I don't know that to be a cold, hard fact.
I've never heard a "new"ish engine make that noise (and mine made that noise at 55k), and I've never heard it again. My 2.0L Duratec never made that noise and my 3.0L Duratec V6 doesn't make that noise. It's probably a CVH/SPI head design peculiarity.
