WTF is that ticking noise???

Hey Gang,

I heard a wierd ticking, or tapping noise in the 5.2 the other day. If I didn't know better, I'd say it sounded like a valve tap. It's speed changes in relation to the RPMs, like a VT would, but it only taps under throttle. It's perfectly silent at idle.

The 5.2L V8 was rebuilt just a year ago, with only 10-12K on it.

Possibly a lifter failing to pump up. If you're lucky, changing to a different brand or weight oil may help - maybe even try synthetic.
