You can put your earmuff right on the valvecover for a quick hear see but I use a stethoscope numerous times throughout the course of a dyno session and if it doesn't sound like a sewing machine under the covers-somethings wrong. Even a solid cam that is adjusted right and happy will sound like this. p.s. I'm starting to hate hydraulics for anything but the most mild of applications. So here's Brian covering all of his bases, dyno test and all. He ships the engine and customer installs it and bam minor but annoying problem right out of the gate. Yup seems about right. This trade....this trade. J.Rob

Every now and then we have a lifter that does this, however usually it does it before we ship the engine. I put an honest 1-2 hours on an engine during break in, and tuning session at a minimum....I like to also try and let the engine sit overnight and resume testing the next day. I've found this really helps with things that might go wrong so we can make changes before we ship the engine. Sometimes you win, sometimes you don't...but I stand behind our engines, and if there's a bad lifter, we'll make it right!
