OMG...Lifter tapping??

I have a 340 w a hydrolic MP.509 w only 2000 mi. on it and if it sits for a period of time (1 mo. or so) it will tick for a little while until the lifters pump back up. How long did you let your car run? This is pretty common and nothing to worry about if it goes away. The lifters that are left w spring pressure on them while engine is shut off for a period of time will bleed back
