10 is KINDA low on a hydraulic roller motor. the lifters will tend to pump down a bit at idle. but if its shooting RIGHT up off idle like as soon as you touch the gas its bouncing up your good. if its sluggish to 1500 or so and then its up around 35-40 get a mechanical gauge. not a aftermarket in dash POS a real mechanical gauge that a garage would use to check it and do so. and if its still reading low and sluggish do a pump before you start getting a rod knock or top end chatter.
