Not a serious problem unless it doesn't go away in 60 seconds or so.
Synthetic oil will help (so I hear, don't use it myself on my I5's).
Are you using a filter with an anti-drainback valve? That will help
a LOT. Sometimes, lifters get old and clogged up a little, especially
if your oil suffers from not enough changes. Viscosity effects it, too.
Even if the lifters need to be replaced, it's not a hellacious job.
They are about $15 each, for 10, and an hour to replace (?)
