I'd say mine is loud. and it's a hydraulic flat tappet...being the first engine I've built, I thought something was wrong, I expected the hydraulic to be quiet, but it sounds like a sewing maching running at full tilt under the hood.

someone said that it was normal and sounded fine. 4,000 miles later, they seem to have been correct!



Sorry guys but hydralic cams should be quiet. If your valve train is noisey then I bet there's too much lash and it won't last long like that. There's should be zero valve lash when the motor is running and there is oil pressure when properly adjusted. That excludes Roades lifters or the rapid bleed down lifters.

Just saying...
