Re: 350 ticking noise but only at idle. What would it be?

thanks for those responses guys.

An update- I drove the truck on my lunch break and when i got back to my parking spot i could hear the noise again. So, i got out a new 5/16 hose that i had and got under the truck and put one end of the hose on the oil pan and one end on my ear and the noise was not any louder at all. Then i put on the flexplate cover and same, not any louder. Next, i put the hose right on the weep hole opening on the very bottom center of the weep hole cover and wow it was twice as loud right there. So its coming from inside the flex plate cover....

I also was listening to the engine as i shifted from drive to neutral to reverse and back and forth a few times. When the trans engages to reverse the noise gets more prominent. I can make the noise by shifting thru the gears like this. So probably next step would be pull the cover? Is it safe to drive like this or should i just park it? The engine and trans feel fine, but i also dont want to hurt anything
