Does anyone have a hydraulic flat tappet setup that is noisy at idle?  I'm noticing noise from the passenger side and I don't remember hearing it last summer.  I'm concerned I have a bad tappet or something which might explain a periodically rough idle.

Are you running an adj. valvetrain? i've heard from some that were running the comp cams & lifters that they were having a noisy idle :shruggy:, i've run the XE274H & 2 XE284H without to much noise, just pull the VCs & scope things out ;)
