Re: hydraulic valve lifter noise

You may be experiencing exactly what I was.  Check the original post 
RE:Annoying Engine Tapping.  The noise probably isn't your lifters, but 
that vaccuum pump located on the side of the engine.  If you look under 
the hood, you'll see what I'm talking about - It's a little bigger than a 
softball and located right next to either the second or third cylinder 
from the front.  Look under there while you have someone crank the car up 
- the noise should be a little heavier than a lifter.  If this is the 
problem, it's not a real problem.  And I don't think there's an easy fix.

Hope this helps.
