Ted, mine has somewhat loud, but harmless lifter noise too. I'll leave them alone for the time being.
But I'm gonna do this very soon: replace the 2 engine shocks. I've already replaced the motor mounts, but I can still feel a tad vibration of the engine body transmitted thru the car's chassis. "Blame" it on my creamy smooth idle, and my desire for a vibration-less wait at the stop-lights.
