I have searched and can only find threads about the tapping noise on start up. Mine has been making a tapping noise since it was almost new. It does not do it on start up but rather after it has warmed up. I first noticed it while in a line at a dive up window. You could hear it echo off of the building.
This sounds like a lifter noise. I had a Vortex Muffler put on a few days ago and the muffler guy let me watch as he started the AV and raised it back up on the lift to check for leaks. We noticed the noise a lot more from under the AV and it sounded like there were two tapping noises, one from the bottom of each side of the engine! They are not a knock, just a tapping sound. They don't seem to be getting any louder (about 9,000 MILES)
I have taken my service manager out to listen to it at least twice and he just says "Yea, these engines are not as quite as they used to be"
Sorry for the long post but I want to know if anyone else is having this noise. I have read about some users changing their PCV valve. Did that cause any tapping noise?
