I've got an 02' TA with a built 346, and a turbo.. I was out playing around last night and was coming to a stop and down shifted and accidently went to 1st instead of 3rd, and I pulled into the parking lot and noticed a tapping noise. The tapping noise speeds up when I bring the RPM's up. and slows down when the RPM's slow down. Any ideas at what It might be, and how I can check it out..? Thanks....

Well, I pulled the valve covers and the push rods. Man these things are pretty. lol. anyway, they look fine. I rolled them on my super expensive glass breakfast table, and they seem to be fine.. The springs seem to be fine as well. I was told that if I pulled the lifters that I may not be able to tell which one is bad. Is this strue.? Thanks guys..

A fuel injector can tick also. Try a mechanics stethoscope to pinpoint it.

Well, I'm pulling the motor as we speak. The push rods and springs looked ok. I used a mechanics stethoscope and the noise was more like a metallic tapping. The oil pressure was an issue way before all of this. For some reason, when the car warmed up the oil pressure would sometimes drop to "0" if I came to a quick stop. Yeah, scarry.. I wanted to change the rear main seal, and shim the oil pump, so now is a great time to do that. lol.
