If you rev her up and the ticking doesnt increase, it might be an exhaust leak. I had a truck that did that and I thought it was the lifters but it was a hole in the pipe next to the firewall.

Depending on where it is and how big/small a hole makes a big difference as to the sound it makes.

Let us know what u find. Good luck
