Default 2001 lifter rattle

Got my Dynatech Supermaxx LT's installed last night (finished). 2001 Coupe - Car hasn't been run for probably a month or so, and the back end has been up on jackstands slightly higher than the front end.

When I started it up, The Drivers side lifters seemed to "tick" or rattle for the first 2 - 3 minutes - First I thought it was a terrible exhaust leak, but finally figured it must have been lifter rattle since it went away -

Anyone know why this would have happened? The car has sat for longer periods of time w/ no lifter rattle on start up, and it has less than 4 miles on the oil change - so I thought it was strange.

Just curious as to cause.

I wonder if the lifters lost oil and had to pump some back in to quiet down? Just a guess!

that was my thought, although it was just an un-educated guess. I just couldn't figure out why that would happen.

Thanks for your input.

Trust me, we’ve all experienced this at one time or another. Seems like every other oil change it happens, where a lifter bleeds down, gets a pocket of air and won't fill back up with oil right away. Sometimes you have to rev it a bit to fill the lifter again.

Have also heard that valvetrain noise is amplified w/ headers due to thinner header material vs heavier cast-iron of stock manifolds.

Glad to hear that my "revving" to hear the headers didn't durt the lifter, but might have actually helped solve the problem. THANKS!!!
