My Van started making a ticking noise when idle and moving slow, stops ( or at least I can’t hear it) when we reach speeds over 30mph, had timing belt replaced recently, checked oil, ac has been replaced
You need to take it to a shop so a mechanic can listen to it with a mechanic’s stethoscope to narrow down wher the sound is coming from. You might could use a length of garden hose yourself, see if you can narrow down the location. Theres so many possibilities that it would just be guessing until you narrow down what’s causing it.
Did the mechanic adjust the valve lash when the timing belt was replaced? I had the same issue on my Accord V6 before the timing belt was replaced. The valve lash was adjusted when the belt was replaced and the noise disappeared.
