OUCH that doesent sound to good.
But it seems to be louder at the back of the Engine.
And it is kind of strange that it suddenly stops for a while.
The first thing i comes to my mind is, check the bolts to the torque converter to see if one of them is loose.
I had that problem on a previus car , i feared the worst but it was only one bolt that came loose.
That sound also come and goes as the bolt turns.
That bolt caused a crack in the flexplate, but i rather have that than a bad rodbearing.
Just an idea to check this, its a lot easier than a rod bearing.
Hope for the best
