Hello, I’ve got a 94 with the 4.0, haven’t had it long so not sure about it’s history…So it has been running fine with no real noise until I tuned it up and changed the oil, after I did that it started ticking, it will come and go so I can’t really pin it down, checked the plugs and wires and all have good connection, messed with it this morning and it all the sudden stopped for the time being….sounds like it’s coming front the front of the engine…..any I sight, I attached a video of it running
