Description:
Sounds like a cat purring with a mallet.
Much stronger than lifter noise
Sounds internal and rhythmic
Does not occur when engine is cold, only when hot.
It happens in neutral and in gear
Occurs mostly between 2k and 3k rpms
Does not occur at wot
Does not occur when decelerating.
Only happens when accelerating or decelerating casually (light throttle)
At first I was leaning towards worn rocker arm components but it was bad this morning when I got to work.
I'm taking the valve covers off when I get home. I hope I don't have to drop the pan.
Thanks.
